3.5 Signal connections
The preamp inputs of the ROM amplifiers feature high-grade RCA connectors; connect the
preamp (line) outputs of your audio source with the RCA preamp level inputs of the amplifier.
Use heavy-duty RCA signal cables designed for mobile applications, like the SIGNAT
Platinum series.
Run the patch cables carefully, maintaining as much distance as possible from power,
speaker, and accessory wiring. Make sure the RCA plugs fit tightly for a secure connection.
SIGNAT ROM amplifiers feature BIC (Balanced input circuitry). The input sensitivity of the
amplifier can be adjusted to the output voltage of your radio using the "GAIN" control.
Remark:
Please avoid any use with "open" (disconnected) input jacks; BIC requires a properly
connected input to the audio source.

Speaker connections

WARNING:
Never connect the speaker leads to the vehicle chassis (ground).
Ensure that all the speakers are connected in phase, i. e. positive to positive and negative to
negative. With most speakers the positive connection is marked "positive" or it is marked with
a (red) dot.
