CAUTION AVIS LFE IN Limiter ON OFF On Off Light Bar Display 15 16 17 18 4 5 AMPSUB210 OWNER’S MANUAL 7 9200 North Decatur St. Portland, OR 97203 • 503.286.9300 • 5 REAR PANEL CONTROLS The AMPSUB210 can be turned on and off independently via the power switch on the front panel, by signal sensing, or remotely by a triggered DC input. Switch 14 , located on the lower edge of the rear panel of the amplifier, selects turn-on functions of the AMPSUB210. If you would like to control the unit’s power on / power off status manually from the front, place the switch in the “Normal” position. If you would like to control the unit’s power-on / power-off status by means of signal sensing, place the switch in the “AUTO ON” position. If you would like to control the unit’s power-on / power-off status by a DC remote trigger, place the switch in the “TRIGGER” position, and connect the remote triggering cable from your triggering device to the jack labeled “IN” next to the switch. When using 12V Trigger or Auto On mode, the unit’s power button will be pushed in and the status LEDs will be illuminated orange in standby condition. Use a 3.5mm phone plug (in the “IN” connector) to make this connection: the tip of the connector is (+) positive, and the sleeve of the connector is (-) negative. A second jack in the same block is labeled “OUT”. This allows for remote turn-on of other devices when the AMPSUB210 is powered on. Use the same polarity for the terminals of this plug. Please read the owner’s manual for any devices you are attempting to connect in this manner to ensure compatibility. Note: The front panel power switch must be in the “ON” position for the 12V triggers or “Auto ON” features to operate. There are 2 pairs of RCA inputs on the back panel of the AMPSUB210. These RCA inputs are labeled as “Line 1 IN” and “Line 2 IN”. They are also designated with an “R” or an “L” as Right channel or Left channel inputs respectively. “Line 2 IN” should be used as the “primary” or normal input for various line level sources that may be available to the amplifier. “Line 1 IN” is a switching input that should be used when a second local source is connected, and will take over as the selected input whenever a signal with a minimum of 5mV of level is present. Whenever there is no signal at the “Line 1 IN” RCAs, or a signal with less than 5mV level, after a 4 second delay, the input will revert back to the normal Line 2 input signal. SPEAKER LEVEL INPUT The AMPSUB210 provides a pair of speaker level inputs for those applications where either of the sources has only speaker level output signal available. The switch routes the speaker level signal to either the Line 1 or Line 2 input. Figure 3. 12V Trigger Figure 4. Power Mode Figure 6.

As an example, if the “Line 1 IN” source was a CD Changer, the delay should be enough to prevent switching back to the “Line 2 IN” source while the changer moves from one disc to another. FRONT PANEL CONTROLS The front panel power switch switches the AMPSUB210 on or off. Red LEDs behind the power button lens indicate power status. Whenever the amplifier’s power switch is in the “ON” position and the amplifier is in “Active” status the Signal LED is illuminated green. If the amplifier is “ON” but in “Standby” status the Signal LED will illuminate orange. 10& RCA INPUT/OUTPUT V Line 1 Line 2 Speaker IN V Line 1 R L Line 2 AMPSUB210 OWNER’S MANUAL 15 LIGHT BAR DISPLAY Light Bar Display On Off Figure 7. Light Bar Display Control This switch controls the lighted bars on the front of the amplifier. These bars light red when the amplifier is in operation. If the amplifier is visible and a low light setting is desired use this switch to turn off the light bars. The other LED indicators on the front panel as well as the power button lighted ring are not affected by this control. SPEAKER TERMINALS Terminals are provided for two subwoofers. Connect the speaker’s positive (red) terminal to the amplifier’s positive (red) terminal, and the speaker’s negative (black) terminal to the amplifier’s negative (black) terminal. NOTE: Use the appropriate gauge speaker wire when connecting speakers to the AMPSUB210. If using two speakers they must be a minimum of 8 ohms each. DO NOT BRIDGE. The speaker terminals are internally bridged. -+ Use Class 2 Wiring Mi...
