operating and maintenance (servicing) instructions in the literature accompanying the appliance.

The lightning ﬂash with the arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the products’ enclosure that may be of sufﬁcient magnitude to constitute a risk of electric shock to persons.

IMPORTANT SAFETY INSTRUCTIONS

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

8. Do not install near heat sources such as radiators, heat registers, stoves, or other apparatus (including ampliﬁers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or third prong are provided for your safety. If the provided plug

• TO PREVENT ELECTRICAL SHOCK, MATCH WIDE BLADE PLUG TO WIDE SLOT, FULLY INSERT.

does not ﬁt into your outlet, consult an electrician for replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at the plugs, convenience receptacles, and at the point where they exit from the appliance.

11. Only use attachments or accessories speciﬁed by the manufacturer.

12. Unplug the apparatus during lightning storms or when unused for long periods of time.

13. Refer all servicing to qualiﬁed personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

MAGNETIC FIELD: !!CAUTION!! Do not locate sensitive high-gain equipment such as preampliﬁers or tape decks directly above or below the unit. Because this ampliﬁer has a high power density, it has a strong magnetic ﬁeld, which can induce hum into unshielded devices that are located nearby. The ﬁeld is strongest just above and below the unit. If an equipment rack is used, we recommend locating the ampliﬁer(s) in the bottom of the rack and the preampliﬁer or other sensitive equipment at the top.

7. Line 1 Input A switching input that can be used if a second source is desir ed 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 to full clockwise position (500Hz) and Subsonic Filter slightly lower than your woofer’s F3 point, or between 9 and 12 o’clock if woofer specs unavailable.

OWNER’S MANUAL

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.

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.

RCA INPUT/OUTPUT

10&7

Line 1 Line 2

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.

re 6. RCA Inputs

Figure 3. 12V Trigger Figure 4. Power Mode

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.

To Speaker

The built in delay of 4 seconds will automatically, in most instances, accommodate the nature of the source connected to the “Line 1 IN” RCAs. 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.

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.
