1. Gain Controls – These controls are used to match the input sensitivity of the amplifier to the particular
source unit that you are using. The controls are factory set to 1Vrms.
2. Bass Boost – This equalization circuit is used to enhance the low frequency response of the vehicle’s
interior. With up to 12dB of boost and centered at 40Hz, the Bass Boost can be adjusted to meet your own
personal taste.
3. RCA Input Jacks – RCA type input jacks for use with source units that have RCA or Line Level Outputs.
A source unit with a minimum output level of 200mV is required for proper operation. However, this input
will accept levels up to 8Vrms.
4. RCA Output Jacks – These RCA outputs allow for a signal to be sent to other amplifiers in a daisy-chain con-
figuration.
5. Speaker Level Inputs – This input will allow the RT251D to operate from source units with speaker-level
outputs. Output speaker leads from the source unit should be tied directly to the wire harness provided
with the amplifier.
Wire harness color codes:
Grey / Black = Source unit right negative (-)
White / Black = Source unit left negative (-)
Solid Grey = Source unit right positive (+) Solid White = Source unit left positive (+)
With the Smart-Engage™ auto-turn-on circuit, a remote turn-on wire is not necessary when connecting
the speaker-level input wire harness to a high powered source unit. The amplifier will automatically turn
on when music is received.
