Subwoofer Amplifiers

Owner's Manual

��

The following list describes the rear panel of the amplifier and control functions (refer to fig. 2 on previous page).

�� These RCA type terminals are for the pre-amp level input signals coming from a processor or

preamplifier.

Important! Use either the Line Level inputs or the “Speaker Level” inputs separately. DO NOT use both, as

damage to the receiver and/or the Subwoofer Amplifier may result.

Warning! DO NOT connect an amplified or speaker-level signal into these inputs.

�� These RCA type terminals carry the same signal that goes into the line inputs. These terminals

are used if an output signal is needed elsewhere in your system. These outputs are full-range outputs.

�� These 100Hz high-pass speaker outputs are for your satellite/main speakers. The

built-in crossover limits the frequencies below 100Hz from being sent to your satellite/main speakers. You may use

these speaker outputs only when using the “Speaker Level” input terminals (#11). Connect your satellite/main

speakers (observing the proper polarity) to the binding posts labeled “Speaker Level Out.”

Note: These connectors are not powered by the Subwoofer Amplifier.

�� These connectors are for the amplifier or speaker-level audio output from an amplifier

or receiver.

Important! Use either the Line inputs or the “Speaker Level” inputs separately. DO NOT use both, as damage to

the receiver and/or the Subwoofer Amplifier may result.

�� This is the amplified audio output of the Subwoofer Amplifier. If the Crossover Switch

(#5) is in the “on” position, the audio output will be limited to the lower frequencies selected by the Frequency

Control (#6). If the Crossover Switch (#5) is in the “off” position, the audio output will be full-range. An impedance

load of 4-16 ohms may be connected to this binding post. Please follow the instructions in the connections section

of this owner’s manual for proper wiring information.

�� This knob adjusts the brightness of the indicator lights on the front panel.

�� If your model features this capability, this switch allows you to select between

110V A.C. (60Hz) or 220V A.C. (50Hz).

Warning! If the voltage setting does not match the A.C. power supplied, damage to the Subwoofer Amplifier may result.

�� This is the power fuse access.

Warning! In the event the fuse must be replaced, the replacement fuse must match exactly the original fuse value.

If the replacement fuse is not of the same value, damage to the Subwoofer Amplifier may result.

Caution! Before replacing the fuse, disconnect the power cord from the power receptacle.

��

Amplifier is not connected to constant A.C.

power outlet.

Make certain that the amplifier is plugged into

an unswitchable A.C. power outlet.

Subwoofer(s) is/are not connected to amplifier

correctly.

Make certain that subwoofer(s) is/are conn-

ected properly (refer to the connections section

of this manual).

Amplifier is not receiving an audio signal from

Pre-Amp/Receiver.

Make certain that there is an audio signal from

Pre-Amp/Receiver and that audio connections

resemble those in the connections section of

this manual.

Electrical short in wiring.

Verify that all connections are complete and

secure, with no stray wires contacting other

terminals.

If problem is in wire itself, replace suspect wire.

Amplifier fuse might be blown.

Replace fuse( if fuse is not readily accessible,

consult your authorized RBH dealer.)

Warning: Before replacing fuse, please see

the rear panel features/controls section (#14)

of this manual.

��

Bad connection(s) to non working subwoofer(s).

Electrical short in wiring.

Verify that all wires are properly connected.

Verify that all connections are complete and

secure, with no stray wires contacting other

terminals.

If problem is in wire itself, replace suspect wire.

If one subwoofer is damaged due to being

overdriven, then it may have a negative effect on

another subwoofer used in a series connection.

Check each individual subwoofer to verify that

each is still operational.

��

The + and - polarity of the subwoofer wire might

be reversed on the subwoofer.

Check the entire system for proper polarity.

Crossover frequency not adjusted correctly.

Adjust crossover frequency by turning the

Crossover Frequency Control clockwise until

desired sound is obtained.

Crossover switch is in the wrong position.

Check Crossover On/Off switch for correct

setting.

6. Crossover Frequency Control: The variable crossover frequency control allows you to set the point of

the low-pass frequencies being reproduced by the amplifier anywhere from 40Hz-180Hz. Try an initial setting of

the crossover frequency control at the midway (12 o’clock) setting. Increasing the crossover frequency will

produce more mid-bass output from the amplifier.

7. Master Volume Control: This dial allows you to adjust the output level of the subwoofer to match the audio

system. For an initial setting, turn the volume control up one quarter of a turn (9 o’clock) position). The volume

control may be adjusted while listening to match the subwoofer output level with the rest of the system.

�� The volume control should be at the minimum setting (all the way counterclockwise) before plugging

the amplifier into an A.C. wall outlet.

Caution! Do not open the amplifier, attempt any modifications or repairs. There are extremely high voltages present

and any servicing must be referred to RBH Sound or an authorized qualified technician.

Attention! Opening the amplifier will void warranty.

Warning! To prevent shock or fire hazard, never permit moisture or any liquid to get into the amplifier. If an accidental

spill occurs, immediately shut off the power, unplug its A.C. power cord and seek a qualified technician for repair.

Caution! To reduce the risk of electric shock, do not remove the cover (or back). No user serviceable parts inside:

refer servicing to qualified personnel.

All safety instructions should be read before this amplifier is operated. Please retain these safety instructions for future

reference. All warnings on the amplifier and in this manual should be adhered to.

�� The amplifier should be situated so that its location or position does not interfere with its proper

ventilation. The amplifier should not be situated on a bed, sofa, rug or similar surface that may block the ventilation

openings, nor should it be placed in a built-in installation such as a bookcase or cabinet that my impede the flow of air

through the ventilation openings.

�� The amplifier should only be connected to a power supply of the type described in this instruction

manual or as marked on the amplifier. Precautions should be taken so that the grounding or polarization means of the

amplifier are not defeated.

�� Power supply cords should be routed so that they are not likely to be walked on or pinched by items

placed upon or against them, paying particular attention to wall receptacles and the point where they exit from the

amplifier.

��The amplifier should not be exposed to dripping or splashing and objects filled with

liquids, such as vases or plants, should not be placed on top of or next to the amplifier. Care should be taken so that

objects do not fall and liquids are not spilled into the enclosure through its ventilation openings.

�� This amplifier should be serviced by a qualified technician when:

The power supply cord has been damaged; or

Objects have fallen or liquid has been spilled into the amplifier; or

The amplifier does not appear to function normally or exhibits a marked change in performance; or

The amplifier has been dropped or the enclosure is damaged.
