5 Channel Operation
This illustration shows how to use your 6 channel amplifier as a 5 channel unit by taking
advantage of the mono bridging capability on all NAUTIC amplifiers.
1. Interconnect Cable Checklist:
- 1/2CH & 3/4CH: Connect the Inputs of channel pair ½ to a suitable stereo source
with quality RCA cables. Repeat these steps for 3/4CH.
- 5/6CH: Connect a mono line Input via Y-adapter from a mono source or single
Left or Right RCA from a stereo source. This has been detailed on previous pages
for reference.
IMPORTANT: Do not connect Left and Right stereo signals together to achieve a mono
signal as this will damage the output stage of the source and possibly the input stage of
the amplifier therefore voiding your warranty.

- POWER LED: Indicates the powered up and turned on condition
- PROTECTION LED: Indicates a high voltage, low voltage, short circuit,
hard clip, over heating or DC fault condition.
- MODE: "2" indicates one set of RCA's are being used. This will also pass signal to channels 3/4 and 5/6 through
1/2 inputs. "4" indicates connecting 2 sets of RCA's to 1/2 and 3/4 inputs. "6" indicates connecting 3 sets of
RCA's to channels 1/2, 3/4 and 5/6.
3. Crossover frequency control checklist:
N/A for full range operation.
4. Line Level:
Refer to section "Setting up systems after installation for best performance."
2. Filter Switch:
- 1/2CH: FLAT
- 3/4CH: FLAT
- 5/6CH: LOW
3. Crossover frequency control checklist:
N/A for full range operation. 5/6CH set to 80Hz.
4. Line Level:
Refer to the section "Setting up systems after installation for best performance."
5.Speaker Connections:
Connect the subwoofer - to Ch6- and the subwoofer + to Ch5+. Connect the remaining
speakers in standard stereo wiring to CH1/2 & CH3/4.
IMPORTANT: Minimum final loudspeaker impedance presented to the amplifier is
4-Ohms in mono operation and 2-Ohms in stereo operation.
