IMPORTANT SAFETY INSTRUCTIONS

READ BEFORE OPERATING EQUIPMENT

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 any 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 the third prong are provided for your safety. If the provided plug 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 plugs, convenience receptacles, and the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service 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.

WARNING
Do not ingest the battery, Chemical Burn Hazard (The remote control supplied with) This product contains a coin/button cell battery. If the coin/button cell battery is swallowed, it can cause severe internal burns in just 2 hours and can lead to death. Keep new and used batteries away from children. If the battery compartment does not close securely, stop using the product and keep it away from children. If you think batteries might have been swallowed or placed inside any part of the body, seek immediate medical attention.

POWER STATUS INDICATOR [Orange LED Fault Indicator)
If Power Status Indicator displays an orange LED, the amplifier has experienced a problem and entered a fault mode.

THERMAL PROTECTION
This occurs if the amplifier’s internal temperature becomes too high. The Power Status Indicator will change from Green to Orange, and output from amplifier will stop. Once the internal temperature has lowered sufficiently, the amplifier will resume normal operation and output.

DC PROTECTION
If the input signal to the amplifier is too high and excessive clipping occurs, the amplifier will enter this mode. The Power Status Indicator will change from Green to Orange and output from amplifier will stop.Unplug the input connection to the amplifier. Reset amplifier with the power button, lower amplifier volume. Check the signal source and lower its output level as well if necessary.  Reconnect input connection. Amplifier will resume normal operation and output 1f signal levels have been lowered sufficiently. If the amplifier does not exit fault mode, remove all output and input connections then power on amplifier. If the amplifier remains in fault mode, contact support. If the cause of the orange light is still unclear after reviewing this information, remove power and disconnect all input and output connections from the amplifier. Wait at least 30 minutes before reconnecting AC power and attempting to power on again. If the amplifier remains in fault mode, contact support.

Amplifier Operation {From Left to Right]

IEC TYPE POWER CORD RECEPTICAL
Attach one end of power cord here for operation.

FUSE HOLDER (INTEGRATED INTO THE POWER RECEPTICAL)
Fuse:T2A. A spare fuse is also contained in the fuse holder for your convenience. Pull straight out after removing power cord. Both the active fuse and the spare fuse are removed.

POWER SWITCH
Disconnects amplifier from AC power. Set this switch to the OFF position to consume no power.

USB INPUT
USB audio input, connect using included USB Type C Male to USB Type A Male cable. Best used with ButtKicker® HaptiConnect™ software.

LEFT & RIGHT LINE LEVEL INPUT (RCA)
RCA/phono input jacks. Input sensitivity of 50mV. Connect both Left and Right to sum stereo signal to mono.

LINE LEVEL OUTPUT (RCA)
RCA/phono output jack. Use to “daisy chain” signal to a second amplifier.

SPEAKER LEVEL OUTPUT BINDING POSTS – Bridged
Used for connecting to the ButtKicker® BK-GT-PRO transducer. Turn the amplifier off before connecting to the Speaker Output.

FRONT PANEL

Amplifier Operation – Front Panel [From Left to Right)

POWER
Power on or off the BKA-PRO The power indicator LED will illuminate green when the amplifier is on and red when the amplifier is off or in standby mode, activated after ~ 20 minutes without signal

POWER STATUS INDICATOR (Red/Green LED)
Red indicates two possible modes. (1) the amplifier is in Off mode, or (2) the amplifier was on, but reverted to Standby mode after 20 minutes of not receiving input signal. If the amplifier is in Standby mode [Red], and an input signal is reapplied, the amplifier circuits will automatically energize and the indicator light will turn green. Green indicates that all amplifier circuits are energized and ready to function. After 20 minutes of no input signal, the amplifier will revert back to the low power Standby mode. In Standby mode 2 pushes of the power button will turn the amp Off [Red). then On [Green).

CLIP INDICATOR LIGHT (Red LED)
Illuminates when maximum output is approached .

SIGNAL INDICATOR LIGHT (Green LED)
Illuminates when a signal passes through the circuits to the amplifier’s output terminal.

LOW FILTER CUTOFF PUSH SWITCH
Pushing this button engages the low-cut filter which reduces all frequencies below 25Hz [-3d8) at a rolloff rate of 12d8 per octave.

HIGH CUTOFF FREQUENCY
Displays the frequency above which frequencies are rolled off.

REMOTE
IR Sensor for the included remote control.

HIGH CUTOFF FILTER PUSH SWITCH
Engages the High Cutoff that rolls off the higher frequencies [-3db, rolloff rate of 1 2d8 per octave).

VOLUME
Displays the volume level (intensity) of the amplifier.

VOLUME MINUS(-) & PLUS(+)
Adjust the volume level [intensity) of the amplifier.
