•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. 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.

This gives the PA1235 great flexibility for use in many applications, such as driving surround sound speaker systems, in addition to multi-room.

•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.

•Remote Master ON/OFF. Allows the entire PA1235 to be powered ON and OFF by a positive DC voltage ranging between 5 and 30 volts (16mA @ 12V). Specifically, it permits the 12 Volt common CO (Control Output) on the Xantech ZPR68 to power one or more PA1235's ON and OFF automatically with first zone ON and last zone OFF commands.

•Default settings. As received from the factory, Volume level is set to 1 Volt for 35 Watts output, Balance is centered and Mute is OFF, for all channels. Also, pressing the LEVEL (System) RESET switch 2 times within 1 second, restores all factory defaults. The PA1235 will always return to last set values (volume, etc.) after main power shut down or after any power interruptions.

•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.

PA1235 PANEL AND FEATURE DESCRIPTIONS

1.Front Panel. 19" x 5-1/4" panel designed for mounting into a standard 19" Rack Panel.

2.Rack Panel Handles.

3.POWER Switch. When pressed to the IN position, power is applied to the PA1235 [provided the rear panel master AC LINE ON/OFF Switch, item 17, is placed in the ON (I) position]. This is the MANUAL ON position. When pressed again, it releases to the OUT position (MANUAL OFF), turning the unit OFF.

PA1235 specifications

The Xantech PA1235 is a cutting-edge multi-zone power amplifier designed for both residential and commercial audio applications. Renowned for its impressive performance and reliability, the PA1235 offers robust amplification for distributed audio systems, fulfilling various audio needs in different environments.

One of the main features of the PA1235 is its power handling capabilities. It delivers 35 watts per channel across six channels, ensuring that every zone in a multi-room setup receives adequate power for optimal sound quality. This makes it suitable for powering a variety of speaker types, from in-ceiling speakers to outdoor sound systems. Its architecture allows flexibility in system configuration, making it easy to distribute audio throughout a home or business.

The PA1235 employs advanced Class D amplification technology, which maximizes efficiency while reducing power consumption and heat generation. This not only makes the amplifier more environmentally friendly but also enhances longevity and reliability. The lightweight design of Class D amplifiers allows for easier installation, especially in complex multi-zone environments.

Another characteristic of the PA1235 is its multi-zone functionality. Users can easily assign audio sources to different zones, allowing for personalized control of audio in various spaces. This feature is particularly valuable in commercial settings, where different areas may require distinct audio content or volume levels. It offers seamless integration with existing automation systems, thanks to its compatibility with various control protocols, facilitating a user-friendly experience.

The amplifier also features adjustable gain controls for each channel, allowing users to fine-tune the audio output for different speaker types or acoustic environments. Additionally, the built-in protection circuitry ensures that both the amplifier and attached speakers are safeguarded from overload or short-circuit situations, thereby enhancing overall system durability.

With its combination of power, efficiency, and versatility, the Xantech PA1235 is an ideal choice for integrators and audiophiles alike. Whether used in home theaters, restaurant sound systems, or corporate audio solutions, it provides high-quality audio performance that meets the demands of modern audio requirements, making it a prominent player in the audio amplification market.
