4.7 Music Inputs
The music inputs are noise rejecting and have a nominal input impedance of 600 Ω . The max. rated input
level is 1.5 Vrms. The MUSIC LO must be connected to the music source along with MUSIC RIGHT and
MUSIC LEFT. If MUSIC LO is not connected, music volume will be low (or inaudible), noisy, and
distorted.
4.8 Receiver Audio
RECEIVER AUDIO OUT is a 40 mW audio output that is intended to drive a recording device or an audio
panel.
RECEIVER AUDIO OUT supplies 40 mW (4.9 Vrms) into a 600

load, and is generally connected to the
audio panel (if used). This output can also drive a recording device. When driving a recording device the
output level will typically need to be reduced. The output level is controlled through configuration mode.
RECEIVER AUDIO OUT is the summation of the receiver audio, COM sidetone audio, intercom audio,
and AUX audio.
