admin — Sat, 09 Apr 2011 14:10:37 +0000

This beast of a receiver is one step below Denon’s flagship AVR-5308ci.

The Denon AVR4310CI 7.1-Channel Multi-Zone Home Theater Receiver with Networking Capability and 1080p HDMI Connectivity
delivers 9 amazingly clean channels of amplification without breaking a sweat. The GUI-driven menu takes a little getting used to, but after 4 or 5 uses, the menu becomes second nature. There’s a plethora of inputs and outputs, and the capability to handle 3 subwoofers coupled with 9 channels for front, front height and/or width, surround, surround back and center channels allows for enormous flexibility with room for future expansion. There are 6 HDMI inputs (with one in the front panel behind the flip down door).

Built-in WiFi allows for integration of other networkable sources in your home with no mess or fuss. Having Napster and Rhapsody online access built-in is extremely convenient and very easy to use. Satellite radio (XM and Sirius) can be handled by this beauty as can HD radio. With the USB input, you can playback photos or audio. Freely assignable amplifiers allows for bi-amping, bi-wiring and multiple zones (up to 4) throughout your home. This receiver can even control your iPod on-screen via the USB digital direct connection.

The initial setup process is quick and simple, thanks the Audyssey MultEQ XT Room Equalizer that allows the receiver to setup all of your speakers’ time and frequency response, for up to eight positions which is very handy if you have more than one person frequenting your listening area.

The Advanced AL24 Processing Multi Channel features improved dynamics, so my sources sound phenomenal. The 1080p HDMI output via Anchor Bay’s advanced VRS processing (using the ABT-2010 chip) and excellent scaling capability makes all of your sources look simply superb! Even your analog sources can be unconverted and scaled to 1080p!!

As usual, Denon’s Dynamic Discrete Surround Circuit (D.D.S.C-HD) provides for amazing sonic detail and extended range, with Burr-Brown 24-bit/192-kHz digital-to-audio converters for all channels, rather than just the front two. Dolby TrueHD and DTS-HD Master Audio decoders ensure amazing reproduction of your favorite Blu-Ray discs. As a bonus, you get dual HDMI outputs if you want to output to other rooms or to handle situations where you might have both a video projector and an HDTV flat panel in your theater.

The “ci” designation means that Denon AVR4310CI 7.1-Channel Multi-Zone Home Theater Receiver with Networking Capability and 1080p HDMI Connectivity
supports custom integration features if you choose to do some advanced setup or are having the receiver professionally installed/integrated into your home.

Multi Zone Stereo System

admin — Tue, 13 Jul 2010 04:13:52 +0000

Multi zone stereo systems have become very popular. There are several ways to distribute music throughout your home including wired and wireless, powered and non-powered and this article provides an overview of the various systems. In some cases, you can use your stereo receiver or home theater receiver as the center of the system or install a dedicated multiroom music system.

Here’s How:

Multi Zone Receiver with Single SourceThe simplest multizone system consists of a Speaker A/B switch that’s probably built into your stereo or home theater receiver. Install speaker wires between the receiver’s Speaker B terminals and two additional speakers in another room and you have a multizone audio system. It is also possible to connect the receiver to more speakers if you install a speaker switcher with a selector for each room. Multi-zone means multiple rooms and multi-source means the ability to listen to different sources in different rooms simultaneously.
Multi-Zone / Multi-Source ReceiverIf you own a newer multichannel home theater receiver you may be able to take advantage of its built-in multizone/multi-source features. Many receivers have multiroom outputs that can provide two-channel audio (and sometimes video) to as many as three separate zones. In some models, the audio output is speaker level so all that’s necessary is speaker wire and two speakers in each of the rooms; or the audio output is line level (unamplified signals), which will require line level cables between rooms plus an amplifier and two speakers.
Advanced MultiZone / Multi-Source Control SystemsA multizone control system is essentially a switch box that allows you to send a selected source (CD, FM radio, tape, etc.) to a specific room in your home. The control system can be a device that sends a line-level signal to an amplifier in the remote room(s), or it can have built-in amplifiers that send speaker level signals to the selected rooms(s). All of these types of systems allow you to listen to different sources simultaneously in different zones and are available in many configurations from four to as many as eight or more zones.
Whole House Audio NetworkingIf you are fortunate enough to own a home with network wiring already installed, you’ve already got a huge advantage. The same type of wiring used to interconnect a computer network system can distribute audio signals to multiple zones. This type of wiring is known as CAT-5e (Category Five-Enhanced) and is capable of distributing audio signals, though it cannot be used simultaneously for a computer network and audio distribution.
Using a Computer LAN to Distribute AudioAs mentioned, you can’t use the same CAT-5e cables as your computer network to distribute audio, but you can use your computer to distribute audio over your CAT-5e network in the form of MP-3 digital audio files or Internet radio. This is a low-cost solution especially if you already have a computer network installed.
Wireless Music DistributionIf you don’t have a pre-wired home and retrofit wiring is too much to consider, there is another solution – go wireless. As wireless technology has improved, so have the options for wireless distribution of music. The most common wireless technology is Wi-Fi (Wireless Fidelity). No doubt you have heard the term used for the wireless networking of computers. The same technology is now finding its way into home audio.
Wireless Music AdapterThe simplest way to have wireless music distribution is to install a digital media adapter. This adapter, connected to your PC, sends a Wi-Fi signal to another adapter connected to your multizone home theater receiver, enabling you to listen to music in a remote zone that uses your computer as a source.

What Does Amplifier Classes Mean?

admin — Thu, 17 Jun 2010 11:32:15 +0000

The different circuitry design within an amplifier can be determined by classes. The audio amplifier’s class refers to the output stage of the amplifier. There are several classes:

Class A - Class A amplifiers produce very low distortion. The distortion is the lowest when the volume is low. However, Class A amplifiers are extremely inefficient, thus they are not suitable for designing high power models like most multi zone amplifier in the market.

Why do they manage to produce low distortion? The transistors in Class A amp are biased in a way that they are only half working when the amplifier is idle (at this point the semiconductor devices are most linear in behavior). From this, a lot of power is wasted even though there is no audio from the device.

Due to the working mechanism of Class A amplifier, they are often used for signal level circuits. Premium Class A audio amplifiers are sometimes used by the choosiest audiophiles.

Class B: Class B amplifiers are meant for lower cost circuit designs. Sound quality is not a priority. However,do bear in mind, Class B amplifiers are more efficient than Class A amplifier. However, distortion is rife when signal level is low (the term is called “crossover distortion”).

Class B amplifiers is selected when design cost is emphasized. This class of amp is formerly used in pocket transistor radio, clock radio and anything portable whereby sound quality is not important.

Class AB: This class is widely used in home stereos and normal audio amplifiers. Class AB amplifiers boast about the best of Class A and Class B. Think of the efficiency of Class B and the better distortion performance of Class A amplifiers.

In class AB amplifiers, distortion would deteriorates when the signal gets lower. They usually make use of pairs of transistors which are biased slightly “on”. The reason is to eliminates crossover distortion which happens in Class AB amps.

Class C: Never used for audio circuitry and usually operate the output transistor in a state that produces tremendous distortion. Class C amplifiers are most commonly found in RF circuits whereby such crude signal is acceptable. They are extremely efficient though.

Class D: This class of amplifier is the most employed in Multi Zone Amplifiers and Multi Zone Audios. Class D amplifiers use a different method of amplification as compared to earlier classes mentioned.

Class D amplifier operates the output semi-conductor devices as switches (On or OFF) which is vastly different from Class A,B, AB and C operate in the linear mode. Class D amplifier‘s input signal is compared with a high frequency triangle wave, resulting in the formation of “pulse width modulation (PWM) type signal. This type of signal is also known as ‘digital’ signal by layman.

PWM signal would go through a special filter which removes all unwanted high frequency by-products of the PWM stage. The output of the filter would drives the speaker. One of the major advantage of using a Class D amplifier is its high efficiency or low power wastage.

Too Cheap To Buy A Multi-Zone Amplifier, Use A Speaker Selector

admin — Fri, 11 Jun 2010 14:10:08 +0000

The speaker selector is not just a piece of pretty accessory in the audio system. Please be warned that multiple sets of speakers usually can not be hooked directly to a standard audio amplifier without some sort of impedance matching device. This article is written specifically for those of you who still wants to use your old amplifier to distribute multi zone sound instead of investing on a new multi zone amplifier. Bear in mind, if several sets of speakers are run from one set of speaker terminals the amplifier will usually overheat and shut down, and may blow the output stage.

The correct solution is to use either an impedance matching speaker selector with the protection-mode enabled. Curiously, most speaker selectors are made with a dangerous feature: a switch located right in front, to disable the protection. If the protection is accidentally switched off while running multiple pairs of speakers the amplifier will shut down, may blow output fuses, and very well may damage the output stage of the amplifier. As a result, I would advise you to always leave the switch on, irregardless.

One rule of thumb, only put one speaker per pair of terminals (usually red and black) on the amplifier. Do not try to use a surround amp to feed several rooms with one room on the center, one room on the rear surrounds etc. This is due to the way a surround receiver distributes the sound as you may end up with only the voice in one room and only the music in another! The correct hookup for a surround receiver puts surround sound in the main room and sound from the left and right main speakers is distributed.

One recommendation for wiring up a surround receiver is as follows. Run the speaker selector from the front left and front right outputs on the amplifier. Hook your front left & right speakers to the first speaker switch on the speaker selector. You will need to rebalance your surround system by running the pink noise test as the speaker selector will decrease the output to the left and right speakers by a small amount. This allows running the main speakers & the other speakers connected to the speaker selector without one set being louder than the others. If your speaker selector has volume controls, you need to make sure when you use your surround system for movies the volume control is at the same setting it was when doing the pink noise test. You may hook the speaker selector to the ‘b’ speaker switch on the amplifier if speaker volume balance between your main left & right speakers and the rest of the speakers is not an issue.

Another variation is amplifiers with a direct speaker output for zone 2, 3, etc. These are set up to drive 1 pair of speakers, and must be used with impedance matching if more pairs are to be used. The zone outputs allow a second (or third etc) source, for example CD in one room and radio in another.

An impedance matching speaker selector provides multiple outputs from one input, and protects your amplifier from damage. Speaker selectors come with 4-12 outputs. As long as your amp has enough power, you can push as many sets of speakers as you want. Simply connect the speaker selector to your ‘A’ (or ‘B’) outputs and the rest of your speakers on the speaker selector. You can purchase speaker selectors with volume controls for each individual speaker. Another option is in wall impedance matching volume controls, which require no speaker selector. Most of these are set with jumpers at install time, providing the correct matching. If you want to run more pairs of speakers than the speaker selectors or volume controls are made for (usually 12 pairs max. depending on the hardware) you probably want a second amplifier to run the second set of volume controls (or speaker selector) from.

The music signal to your speakers is called alternating current (or AC), because it varies polarity and voltage. This is in comparison to a battery, for example which produces a steady, or DC current. You may picture current as the amount of water flowing in a pipe (the wire) and voltage as the water pressure. AC current can be imagined as a flow that reverses direction and DC as a steady flow in one direction. The analogy is not exact but is close enough to get a picture of what is happening. Standard house current in the US reverses direction (polarity) at an interval (or frequency) of 60 times per second, measures as 60 Hz (Hertz).

Your speakers have a certain amount of resistance to current. Imagine the resistance as a constriction in the pipe, limiting the flow. They have a DC resistance, termed the voice coil resistance, and resistance to AC is called impedance. Resistance and impedance values are measured in Ohms. Impedance is a complex sum of dc resistances, plus the resistance to various AC frequencies caused by capacitance and inductance (normal properties of electrical and electronic devices).

It is usually specified for speakers as nominal impedance, and is referenced to particular frequencies . However, just think of it as resistance to AC for practical purposes. This is usually rated at either 8 or 4 Ohms. Most home amplifiers prefer an 8 ohm impedance. Each time another speaker is added in parallel the impedance is reduced. Visualize several pipes connected together to the same pump, obviously the flow from the pump increases (up to the limit of the pump’s capability). The amplifier is the pump. Two 8 ohm speakers reduce the impedance to 4 ohms, four 8 ohm speakers reduce the impedance to 2 ohms, and so forth.

An amplifier expects (most require) a certain amount of resistance to current flow. The lower the impedance, the more current flows through the output stage of a typical amplifier. This usually flows directly through a transistor (or other amplifying device) and damages the transistor or protective resistors in the output stage. If you get lucky it only blows an output stage fuse. The moral of the story is always use an impedance matching speaker selector, (or volume control) and your amplifier will always see a safe impedance load.

ADA PTM 1645 16-Channel Multi-Zone (8 Zone) Power Amplifier

admin — Sat, 09 Jan 2010 12:57:22 +0000

The PTM-1645 is the pride of ADA. Also known as the “work horse” when it comes to multi-zone sound. While other sixteen channel power amplifiers exist in the industry, none of them come close to the PTM-1645 with respect to performance, size and value.

First and foremost, the PTM-1645 sounds amazing and is one of the main reasons ADA sits atop of the industry when it comes to multi-zone sound. Able to drive eight independent zones, the “work-horse” is also stable down to 2 Ohms – making it capable of driving four pair of 8 Ohm speakers per zone.

In addition, when adding a pair of speakers to a zone (2 pair of 8 Ohm speakers), instead of sharing power between the two pairs, the PTM-1645 nearly doubles it’s output. The PTM-1645 also occupies only two rack spaces (3.5 inches in height) and because it is force-air cooled from side to side, it is specifically designed to be installed in very tightly packed racks. As for value, the PTM-1645 is built like a tank and designed to outlast other electronics out there.
