232-Amp Stereo Mixer/Amplifier

View larger image

The Contemporary Research 232-Amp is a compact, programmable mixer/amplifier aimed at integration with flat-panel displays and video projectors. The versatile amp features a stereo line-level display/projector audio input and two mono aux inputs, and outputs stereo sound at 16/32W RMS. The aux inputs mix levels with the stereo input, and can be set to mute or lower other inputs when active, ideal for wireless mics and paging applications. The Class D amplifier is highly energy-efficient, using 90% of DC power for amplification, operating with very little heat, and consuming almost no power at all when quiet.

When combined with a CR tuner and PoleCat™ pole mount, the 232-Amp serves as an integrated AV tuning/audio solution for video projector installations. The optional SMA bracket (shown above) mounts the 232-Amp to the top of CR tuners, and a single RS-232 port can control a 232-series tuner and amp. IC-series tuner/controllers provide integrated IR remote control of the tuner, amp, and projector, with central control and management from Display Express Web-based software.

Full RS-232 control and status is available, allowing 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 performance manually in the field using onboard switches and level potentiometer.

• Drives stereo speakers at 8W watts per channel @ 8 ohms, 16W @ 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)
• Mounts on projector pole when combined with CR tuner and PoleCat pole mount
• Interfaces with 25/70v paging systems with PAG line-level adapter
• 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)
• Mounts on projector pole when combined with CR tuner and PoleCat PMT pole mount
• Links DC power to CR tuner to provide single power source for amp and CR tuner
• Connects speakers and control from captive screw terminals
• Attaches to top of CR tuners with TMT bracket, next to CR tuners in new RK-1 and RK-HD1 rack kits, or mount in RK-3 rack kit
• Includes 4 A 12VDC power supply (domestic only), and captive-screw control terminals
• Options include:
  • SMA Surface Mount for AV Tools
  • PMT-1 PoleCat pole mount for AV tuners
  • PMT-2 PoleCat pole mount for HDTV tuners
  • PAG Paging/Line Adapter for 25/70V paging speaker input
  • SA-216A Ceiling Speakers
  • CS-206SB Wall Speakers
