Overview
The IC-52B is the most versatile Audio Intercom ever built. Yet it is also the easiest to integrate
into your design. Configuration Templates support every common application. Follow the
Setup and you’re done. If there is not a template for your application, give us a call; we will be
pleased to assist you to configure the IC-52B into your design.
The audio quality of the IC-52B is superb. Noise and distortion are very low. Selectable
equalization optimizes voice communications. The Automatic Level Control assures optimum
performance. There are separate controls for Audio Level, and Reach. Once set, the Audio
Level remains constant over wide dynamic input range. The independent Reach Control allows
for optimized accommodation of the input signal level. The user may wander throughout the
room, and still be heard at a nearly constant level without any operator adjustments!
Hands-Free operation is easily achieved with the IC-52B. The selectable Voice Operation
(VOX) operates flawlessly. Electronic switching takes less than 3mS. Setup indicators make
adjustments easy
The IC-52B incorporates two selectable Notch-Filters to reduce acoustic feedback. One filter
has an optimized frequency range to compensate for poor room acoustics. The other has a
higher frequency range to reduce microphone to wall/glass resonance.
In every way the IC-52B is the Universal Audio Intercom Amplifier Solution. The logic interface
has a plethora of Inputs and Outputs. However standard functions require few wires. The
Indicators are comprehensive, yet a simple. The interface is fully configurable, with jumpers,
however common functions are preset. Audio controls are on the IC-52B front panel.
Line Level, 0dBm Outputs may be configured for Paging, Monitoring or Logging
Jumpers allow for Audio Signal Selection, and Keying
The Tech Works PA-BUSS Line Level Output is fully configurable.
Pre-emptive Music is accommodated using the Tech Works PA-402 Power Amplifier
Modular Construction makes the IC-52B ideal for integrated designs. The unit is small; mounting
is flexible, and easy. Power is from a Universal Plug-in D.C power adapter. All I/O is through
Euro-Style connectorized barrier strips.
The IC-52B has major improvements, over its predecessor:
Universal Microphone/Line Inputs
Phantom Power now 22 Volts Current Limited (used to be 10 Volts)
Gain Structure change; Rotary Microphone Gain Control, Trim-Pot Speaker Level
25 Volt, 10 Watt Speaker Outputs
Line Outputs, inbuilt, no Option PCB required
PA-BUSS Output Connector, Easy Connectivity to other Tech Works Products
Privacy Tone removed
