Overview
|
- 12 internal individual amplifiers can power up to 6 audio zones, 12 speakers
- Internal amplifiers can be driven individually or bridged to suit almost any application
- Use a single source for all zones or a different audio source on each zone
- Volume on individual zones or all zones can be controlled via infrared (IR)
- LED status indicators on the front panel of the amplifier
Essential Info
The most essential component of any whole-home audio system is the amplifier. This 12 channel amplifier will provide enough power for large applications with control of up to six different zones (pairs of speakers). Each channel ( speaker) is powered by a 35 Watt amplified output, enough to deliver for a full spectrum sound experience. However, this versatile device also allows for the internal amplifiers to be bridged, creating greater audio output for specific channels. A single source (TV, iPod, MP3 player, CD player, turntable) can be connected to the "Common Bus" so that each zone has the same audio output. Alternatively, the amplifier is flexible enough to let each zone be fed audio individually via a "Local Inputs" from differing zones or sources; this means you can have audio from your TV on in the home theater, music from your iPod or MP3 player on throughout the house, and sound from your CD player on in the backyard. Volume control can be set manually on the amplifier for the entire system or for each zone individually. Another option is to install a volume control between the amplifier and your speakers. For advanced setups, the amplifier features built-in in infrared (IR) control capability, letting you use an IR System to remotely control volume from each zone. It also features LED status indicators that will let you know which zone or zones are active at all times; you can conserve energy by turning off zones that don't need to be active. The 12-Channel, 6-Zone Power Amplifier with IR Control is perfect as a shelf top or rack-mount component, and provides a great foundation for audio distribution and control throughout any home or office. Please Note: Speakers, volume controls and IR systems sold separately. Variations of this amplifier sold separately are: 12-Channel, 6-Zone Power Amplifier without IR Control
6-Channel, 3-Zone Power Amplifier with IR Control
4-Channel, 2-Zone Amplifier without IR Control

12-11-10-9-8-7-6 Output Flexibility
Each of the 12 amplifiers can be driven singly or bridged to allow several channel and power output capabilities. This gives the 12-Channel, 6-Zone Power Amplifier with IR Control great flexibility for use in many applications, such as driving surround sound speaker systems in addition to multi-room speaker systems. It can be configured into seven power packages as follows:
Twelve 35-watt amplifiers - 12 total
One 150 and ten 35-watt amplifiers - 11 total
Two 150 and eight 35-watt amplifiers - 10 total
Three 150 and six 35-watt amplifiers - 9 total
Four 150 and four 35-watt amplifiers - 8 total
Five 150 and two 35-watt amplifiers - 7 total
Six 150-Watt amplifiers - 6 total
Status LED Indicators
These indicators, one for each channel pair, provide the following status information:
They show Power ON/OFF and Standby ON/OFF conditions.
They flash Amber 5 times during power up, then turn steady Green when Power On Mute releases.
On power down, they flash Amber once, then go off.
This action occurs whether the unit is powered ON and OFF by the POWER switch or by a DC voltage applied to the REMOTE MASTER ON/OFF CONTROL terminals
They will go Off when the Standby OFF IR command is received. Sending a MUTE OFF command will restore operation. Also, LEDs blink with Volume action.
A Mute command will cause them to blink Green (Red if Volume is within 5 dB of Max-V). Mute is released when any other PA1235 command is sent.
Changing an IR Code Group will cause them to blink Amber, confirming the change has taken effect.
When the volume level is increased to a range within 5 dB of MAX-V, the LED color changes from Green to Red. NOTE Red indicates that volume is approaching maximum , not an indication of power output level.
Individual ON/OFF of Amp Pairs
Permits Standby ON/OFF control of individual channel pairs. Specifically, it permits the STATUS outputs (12 Volts On/Off) of Xantech ZPR68 zones to switch the Standby of the PA1235 channel pairs (CI) On and Off with zone ON and OFF commands.
Volume Setting Capabilities
Once installed, you have the option of using the volume control of the amplifier as the sole volume control for a zone or the whole system. The volume control can also be used to adjust the amplifier volume to a desired fixed level and use the volume action of a connected preamp instead. Additionally, a maximum volume setting can be established, which allows the amplifier to be set to deliver a controlled maximum sound level into a zone when the volume is ramped to maximum. This acts as a volume limiter for the system (e.g. to prevent the kids from over-driving wall speakers, etc.).
Low Impedance Capability
Each amplifier is 4-Ohm safe under music conditions in stereo mode and 8-Ohm safe when bridged. This means, for instance, that you can drive two pairs of 8-Ohm speakers in stereo mode in each zone.
Local or Common Bus
Each stereo pair can be fed audio individually via their LOCAL inputs from differing zones or sources. In addition, a single source can be fed, via the COMMON Bus, to some or all stereo pairs as desired. This flexibility permits the installer to drive as many as six rooms in stereo as a single zone system, or six rooms in stereo as a six zone system, or divide them up for a combination of both.
STEREO, MONO and BRIDGED Modes
In STEREO mode, the two amplifiers operate independently of each other for 35 Watts of output each, except IR control of Volume, Max-V, Mute, Standby OFF/ON and Balance functions is common to both. In MONO mode, left and right input signals are summed internally for Mono output from each of the two amplifiers. Also, either the Left or Right input may be used if the source is already a Mono signal. In BRIDGED mode, the two amplifiers are bridged for a single channel of high power output (150 Watts @ 8 Ohms). Either the Left or Right input may be used to drive the resultant single channel amplifier.
Speaker Terminals
These plug-in 4-terminal screw type connectors permit speaker wire sizes up to 12 gauge.
IR System
Since the 12-Channel, 6-Zone Power Amplifier has an IR control system for each amplifier pair, it can be configured so that each individual room, in a multi-room system, can have Line Level Volume, Mute, Balance, and Standby ON/OFF action via IR or Smart Pad control. This eliminates the need for speaker level volume controls and their attendant power losses and reduced sound quality. A basic Common IR Bus system using a low cost approach requires that a dedicated remote be used in each room that has an IR receiver; that is, remote commands for Volume, etc., are specific for each room. A basic Dedicated IR System can be setup so that each remote room has a Dedicated IR path going to the amplifier pair that controls it. The IR bus is not connected in common, it eliminates the need for dedicated remotes, allowing you to carry the same remote(s) from room-to-room; that is, remote commands for Volume, Mute, etc., will work in any room from the same remote.
