SECTION 1 - DESCRIPTION
1.1 System Overview
The JA35-100 audio summing amplifier is a six channel bulkhead mounted isolation audio amplifier with separate
level controls for each channel. It provides two summed output channels with individual level controls, and two
emergency bypass channels for critical audio sources.
The JA35-100 is set up on a per-installation basis using a configuration cable and a PC running the (ProCS) product
configuration tool to download system configuration settings via the configuration connector.
1.2 Features Overview
All JA35-100 internal settings are quickly adjusted using the proprietary ProCS (Product Configuration Software). The
configuration commands set the level of non-volatile digital control potentiometers to control audio signal levels and to
non-volatile expander latches which are connected to audio gates to control the audio signal routing.
The JA35-100 audio summing amplifier provides differential receive audio inputs for high common mode noise
rejection.
The JA35-100 has two modes of operation: Normal Mode and Emergency Mode
1.3 Inputs and Outputs
