Connecting the SUBAMP

Caution: All connections and switching must be done with the amplifier turned off. Connect the power cord last to ensure that the amplifier is off during all the connections and set up.

Cabling considerations

  • RCA line-level cables - Use high-quality RCA cables that feature low impedance with adequate shielding and high-quality connectors.

  • XLR audio cables - Use high-quality XLR cables. For best performance, the XLR cable should be fully balanced providing separate conductors for Positive, Negative, and Ground signals. The cable should also be shielded.

  • Speaker wiring - Use 14 gauge stranded two-conductor speaker wire or better. Connect the appropriate conductor to each screw terminal, observing correct polarity.

Connecting the audio input and speaker cables

  1. Connect audio out of the source (for example an AVR) to the input of the amplifier. Connect stereo RCA cables to L and R or a mono cable from a SUB or LFE output to the L (LFE) input or XLR cables to the BALANCED L and R inputs or a single XLR cable from a SUB or LFE output to the L (LFE) input.

  2. Connect the speaker wire for the subwoofer on channel 1 (SUBAMP700/1200/2400) and the subwoofer on channel 2 (SUBAMP2400 only). Make sure to keep the polarity of the wires straight, connecting + to + and - to -.

  3. If connecting another amplifier, you can connect RCA or XLR cables from the OUTPUT to the INPUT of the other amplifier.

12V DC trigger

  1. Connect the 12V trigger output of another device to the 12V trigger input of the amplifier using a high quality mono cable.

  2. If connecting another amplifier, you can connect another mono cable from the TRIGGER DC 12V OUT to the IN on the other amplifier.
