This 6-Zone home audio multizone 12-channel amplifier is a 12-channel audio distribution amp that can be configured for six stereo 4-8 ohm zones, six stereo 70/100V constant voltage zones, or three high powered 8-ohm bridged zones. It supports any combination of stereo, bridged, and constant voltage zones. It delivers 30 watts per channel into 8 ohms, 50 watts per channel into 4 ohms, or 100 watts into 8 ohms in bridged Mode. Each zone can be controlled using the included IR remote control or RS-232 computer control. The RS-232 section is bidirectional, with an easy to configure command structure. It can be configured to automatically send Zone status updates or respond to queries to confirm Zone status and settings.

This Digital to Analog Audio Converter converts Digital Coaxial or Digital Optical (To slink) audio signals into stereo analog audio signals for connection to an external device, such as an amplifier, using standard RCA audio cables.

Simplify the task of running distributed audio for restaurants, hotels, or anywhere large areas need background music and/or paging address systems. Connect hundreds of speakers covering acres of area without the need for large equipment racks.

A constant voltage speaker system differs from a traditional 8-ohm speaker system in that it uses a step-up transformer at the audio source to raise the voltage and lower the current on the transmission line. At the speaker end, a step-down transformer converts the signal back to a normal speaker level voltage. This reduces power loss during transmission, which allows for the use of longer speaker wire runs using smaller gauge wire.

Additionally, a constant voltage speaker system allows for the use of multiple speakers on each channel, without the need for complicated impedance calculations and configurations. In a constant voltage system, all speakers on a given channel are connected in parallel and the complicated impedance calculations are replaced by simple wattage calculations.

For example, if you want to connect two speakers per channel in a traditional 8-ohm speaker system, you must either connect them in series, which results in an overall 16-ohm impedance, or in parallel, which results in an overall 4-ohm impedance. In the first case, the 16-ohms impedance effectively halves the output power of your amplifier, resulting in lower overall volume levels. In the latter case, the 4-ohms impedance means that your amplifier will have to work harder and must be rated as stable at 4 ohms. Adding a third speaker to the mix would complicate it further, producing either a 24-ohm or 2-ohm overall impedance. Note that very few amplifiers are stable under 2-ohm loads, so that is usually not an option.

On the other hand, with a constant voltage system, you consider first the RMS output wattage of the amplifier. This should be reduced by 20% to compensate for insertion loss. For example, if using a 100-watt amplifier, the total load from speakers should not exceed 80 watts.

This amp features three combination XLR/TRS balanced/unbalanced inputs, which can be set to accept a standard microphone input, a microphone input with +48V phantom power, or a line level input. It also has two unbalanced stereo RCA line level inputs. It has four independent 120 watt amplifiers, which can drive 4-ohm loads or a 70V or 100V constant voltage speaker array. A Media Player is included, which features a built-in FM tuner and an mp3 player, which can playback files from a drive connected to the USB port or an SD™ card inserted in the SD/MEDIA slot. It includes thermal, short-circuit, clipping, and overload protection circuits, as well as a ground lift switch. It can interface with external phone systems for telephone paging.

Spread Your Music Everywhere. One of the most popular trends in Home Audio is whole house audio distribution. Unfortunately, true multi-zone distribution systems are normally built into only the higher end receivers or require an expensive audio distribution network. Monoprice brings everything within reach of the average homeowner by offering a wide selection of Home Audio Distribution accessories. A Key element of any home audio distribution system is a speaker selector. The speaker selector allows you to distribute your source signals to several sets of speakers distributed throughout your home. Additionally, a good speaker selector like our 2-channel A/B selector listed here, will allow you to have different source audio sent to different rooms so that someone in one room can be listening to something different in another room. Most importantly, a speaker selector provides impedance matching, which ensures that the additional speakers do not overload or damage your amps. The Monoprice MSV-2 is a dual source 2 zone speaker selector with built in independent volume controls for each source. This device can handle up to 100 watts per channel. It supports a frequency range of 20Hz to 20kHz. Accepts wire gauges up to 14AWG and maintains load at 8ohms. Installation is straight forward and simple. This is part of making your dream sound system into a reality.

The wall plate controller connects to the multizone amplifier using Cat5e or Cat6 cable (Cat6 preferred). It features an infrared eye, which can propagate single-band IR remote control signals to individual IR transmitters connected to the master controller. This allows you to control the source devices from each zone using native remote controls. The controller features lighted, soft-touch buttons for comfort and ease of use.
