Amplifier remote power on (blue)
This line can also be used to control an automatic
antenna, with the same proviso on current sourcing as
above. Note that the antenna will extend whenever the
empeg is switched on, regardless of whether the tuner,
digital audio or auxiliary source is selected. Some empeg
tuner modules may have a dedicated antenna control
output which would be preferable for this application.
Mute input (green)
This 12V input is used to automatically mute or pause the
audio output. This is primarily intended for use with an in-
car cell phone.
Audio
There are two pairs of audio outputs on phono (RCA)
connectors, with an output level of approximately 3.2V
RMS. The 1V line inputs can take audio from other head
units or portable CD/DAT/Minidisc players and route it
through the empeg Aux channel.
The microphone input is suitable for connection to a
passive condenser mic or an active DSP mic.
Digital
The empeg car’s serial port docks with the car mounting
cage, allowing connection to permanently fitted in-car
computer equipment. The connector provides transmit,
receive, flow control, ground and +12V outputs on a 9
pin RS232 connector.

If this connector is not used, care must be taken to
ensure that it is insulated due to the 12V output
present on pin 4.
This line is used to turn the external amplifiers on. It
should NOT be used to power the amplifier, as it is a
low current line, which can supply a maximum of 1
amp at 12V – this should be connected to the
amplifier’s ‘Remote’ line, with the amplifier drawing
its power from a direct battery feed.
