Instructions

1. Connections

The subwoofer is provided with both line level inputs via a pair of phono
connectors and hi-level (speaker level) inputs on a pair of binding posts. Only
one type of input should be used at any one time. The rear panel also features
the mains power input, voltage selector, fuse, remote trigger input and standby
indicator LED. The rear panel input connections are shown in Fig. 1 below:

Audio Input Options
Line Level Inputs: These should be used to connect your subwoofer to preamp outputs or integrated
amplifier preamp outputs. For stereo use, use both connections. In a 5.1 system, only connect to one
input. Either left or right is fine and will give the same results.
Hi-Level Inputs: These should be used to connect your subwoofer directly to a stereo pair of speakers,
either via the amplifier outputs or the loudspeaker input terminals themselves. Take care to maintain
correct polarity throughout.
Control Input
The subwoofer is also provided with a trigger input on 3.5mm mini-jack so the subwoofer can be
remotely powered up. The 'tip' pin of the mini jack should be connected to trigger signal and the 'ring'
to ground.

2. Functions/Settings

All functions/settings on the C1 Sub are controlled via a rotary encoder on the front display panel of
the unit and shown in Fig.2 or by the supplied IR remote control. Pushing the encoder knob cycles
through the settings and turning the knob clockwise/anticlockwise increases/decreases the function
value respectively. From the IR remote, Left/Right cycles through the settings and Up/Down
increases/decreases the function value respectively. Below is an explanation of the functions/settings.
