Contemporary Research 232-Amp+W Stereo Mixer/Amplifier with Mounting Wings
Key Features
  • Full RS-232 Control and Status
  • Drives Stereo Speakers at 16W @ 8 Ohms
  • Drives Stereo Speakers at 20W @ 4 Ohms
  • One Stereo Input, Two Mono Inputs
The 232-Amp+W from Contemporary Research is a compact, programmable mixer/amplifier that ships with integrated mounting wings, aimed at integration with flat-panel displays and video projectors. This versatile amplifier features a stereo 1/8" line-level display/projector audio input, two 1/8" mono aux inputs, and two stereo speaker outputs each capable of 16W RMS at 8 Ohms or 20W RMS at 4 Ohms. The aux inputs mix levels with the stereo input and can be set to mute or lower other inputs when active, which is ideal for wireless microphones and paging applications. The 90% efficient Class-D amplifier utilizes a switch-mode power supply and operates with very little heat, and draws almost no power when quiet.

Contemporary Research 232-Amp+ Overview

The 232-Amp+W from Contemporary Research is a compact, programmable mixer/amplifier that ships with integrated mounting wings, aimed at integration with flat-panel displays and video projectors. This versatile amplifier features a stereo 1/8" line-level display/projector audio input, two 1/8" mono aux inputs, and two stereo speaker outputs each capable of 16W RMS at 8 Ohms or 20W RMS at 4 Ohms. The aux inputs mix levels with the stereo input and can be set to mute or lower other inputs when active, which is ideal for wireless microphones and paging applications. The 90% efficient Class-D amplifier utilizes a switch-mode power supply and operates with very little heat, and draws almost no power when quiet.

Full RS-232 control and status allows for integration with custom control systems. In addition to setting master gain and input levels, the commands can also set max and minimum gain, and aux input threshold and ducking levels. Installers can adjust the performance manually in the field using the on-board switches and level potentiometer. The 232-Amp+ ships with a power supply and two 5-pin captive screw terminals.

  • Full RS-232 control and status is available, allowing integration with custom control systems
  • Master gain and input level settings
  • Drives stereo speakers at 16W per channel @ 8 Ohms, 20W per channel @ 4 Ohms
  • Mixes one stereo line input with two mono inputs
  • Mono inputs can "duck" other inputs, with programmable ducking on/off, threshold, timing, and mute levels
  • Features programmable input levels, maximum and minimum gain, and volume (volume affects stereo input, mono inputs are fixed)
  • UL 2043 plenum rated
  • Mounts on projector pole when combined with optional CR tuner and PoleCat pole mount
  • Offers field adjustment with onboard DIP switches and level potentiometer
  • Integrates via 2-way RS-232 with three options:
  • Connect to data link on new iC-Net tuners for interactive volume control
  • Control from AMX, Crestron or other custom control systems
  • Daisy-chain RS-232 control with a 232-series tuner (Amp is Device 1)
  • Links 12 VDC power to CR tuner to provide single power source for amp and CR tuner (less Watts at 12 VDC)
  • Connects speakers and control from captive screw terminals
  • Includes 3 A 18 VDC power supply, and captive-screw control terminals
  • Integrated mounting wings simplify surface mounting
  • Compatible with optional PMT-1 Pole Mount for 1RU CR tuners, SMA Surface Mount for AV Tools, RK-1 Rack Kit to mount 232-Amp alongside CR analog 232-series tuner, and RK-3 Rack Mount Kit for mounting up to 3 AV Tools across in 19” rack, 1 RU, back edge pre-drilled for rack kit
