JA94-R62A Dual Audio Controller - Remote Mount - Mixing Amplifier
1.1
System Overview
The JA94-R62A Dual Audio Controller - Remote Mount - Mixing Amplifier is a derivative of the JA94-001A and all data
contained in the JA94-001A Design Specification is applicable to the JA94-R62A except as described in this
document.
The JA94-R62A sums up to 6 channels of audio for each of the Mixer 1 and Mixer 2 outputs.
The JA94-R62A sums 2 channels of audio to the Mixer 3 outputs.
The JA94-R62A provides a passive emergency mode that directs the Mixer 1 Input 1 and Mixer 1 Input 4 to the Mixer
1 Output.
The JA94-R62A provides a passive emergency mode that directs the Mixer 2 Input 1 and Mixer 2 Input 3 to the Mixer
2 Output.
The JA94-R62A is set up on a per-installation basis using a configuration cable and a PC running the product
configuration tool to download system configuration settings via the configuration connector. To facilitate future
customizations and certification, neither software nor complex electronic devices are used in the JA94-R62A design.
1.2
Features Overview
All audio input and output levels are adjustable using the configuration tool ProCS (Product Configuration Software) to
write configuration commands via the JA99-001 configuration cable to the configuration connector. 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 JA94-R62A supports up to 6 audio inputs for mixer 1 and 2 outputs.
The JA94-R62A supports up to 2 audio inputs for mixer 3 outputs.
The JA94-R62A has two modes of operation: Normal Mode and Emergency Mode.
