OWNER'S MANUAL
FRONT PANEL CONTROLS
1. Power
The front panel power switch switches the AMPSUB210 on or off. Red
LEDs behind the faceplate indicate power status. Whenever the amplifier's
power switch is in the "ON" position the ring around the button is illuminated.
2. Signal LED
When the amp is "Active" (receiving signal) the side lenses become
illuminated and the signal LED shows green. During "Standby" status (no
signal) the side lenses are not illuminated and the signal LED shows orange.

7. Line 1 Input
A switching input that can be used if a second source is desired and will
take over when a signal is present and has at least a 5mV level. Whenever
there is no signal at this input, or a signal with less than 5mV level, the
amplifier switches back to the Line 2 or "primary" input.
8. Speaker Level Input Line Select
Switches the input of the speaker level input to Line 1 or Line 2.
9. Speaker Level Input
Can be used to connect a source with speaker level output instead of line
level outputs. Use the Speaker Level Input Line Select to route the source
to Line 1 or Line 2.
10. Line 2 Input/Output
The primary line level input and output for a single source connection.
11. LFE Input
Optional connection to LFE output from your receiver. Bypasses amplifier
volume control, use receiver to set levels. Also set Variable Crossover
full clockwise position (500Hz) and Subsonic Filter
woofer's F3 point, or between 9 and 12 o'clock if woofer specs unavailable.
See block diagram (figure 5) on page 5.
12. Soft Limiter Switch
When "ON" reduces extreme signal peaks which may damage your speakers
and cause audible distortion.

Blinks red during signal clipping or protect. For clipping: reduce volume
slightly. For protect: check speaker wires for shorts or extreme low
impedance (< 4 ohms).
4. Subsonic Filter
Set between 5Hz and 50Hz to filter out unwanted lower frequencies.
5. Variable Crossover
Sets crossover frequency between 40Hz and 500Hz.
6. Volume Control
Adjusts amplifier volume.

14. Power Mode
Sets the power on option of the AMPSUB210. Set it to Normal for manual
power on/off. Set to Auto-On for signal sensing. Set to Trigger if the 12V
Trigger input is used.

Light Bar Display Control
Turns light bar display on front panel on or off. Does not control Signal/Clip
LEDs or power button light ring.
16. Speaker Output
Dual internally bridged speaker output terminals. If connecting two speakers
they must be minimum 8 ohms each. DO NOT BRIDGE.
17. Mains Power Inlet & Fuse Holder
Accepts IEC type line cord. A fuse in the integrated holder provides safety
to

protection from fault conditions: replace fuse with one of same type
and rating only.
18. Mains Voltage Selector
Voltage selection switch is preset to 115V (USA). For use in areas which
require 230V contact your dealer. Fuse must be of type and rating marked
on amplifier for use at local mains voltage.
