ARC SUB10/DS-10 CONTROLS AND THEIR FUNCTION

1. Volume Control - adjusts the level of volume of the
subwoofer relative to the rest of the system.
2. Power LED - This light will be RED when the unit is
plugged in and not receiving a signal; when the unit
receives a signal, the light will cycle to GREEN. If no
signal is received after 5 minutes the light will cycle
back to RED (standby) until a signal is present again.
3. Crossover Frequency - This controls the highest
frequency the subwoofer will reproduce. It allows a
seamless transition from the subwoofer to the
satellite speakers. When the control is at the "50"
position, very few high frequencies will be heard.
This position is best suited to large main speakers.
For most applications, the control should be set
somewhere near the mid position. For listeners using
very small speakers, best results will be obtained
with the control at the "150" position.
4. Low Level Input Jacks - These left and right Line
Level Inputs are normally used when the receiver/
processor has line-level "pre-amp out " or "subwoofer
out" jacks.
5. High Level Inputs - These High Level Inputs are for
receivers that do not have line-level "pre-amp out"
or "subwoofer out" jacks. When a pair of main or
satellite speakers are attached to the OUTPUT
terminals, frequencies below 180 Hz are attenuated
by the high-pass filter.
