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 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 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.

Warnings and Cautions

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

CAUTION: TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT, FULLY INSERT.

CAUTION: RISK OF ELECTRIC SHOCK. DO NOT OPEN. [ATTENTION: RISQUE DE CHOC ÉLECTRIQUE. NE PAS OUVRIR.]

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. [ATTENTION: POUR RÉDUIRE LE RISQUE DE CHOC ÉLECTRIQUE, NE RETIREZ PAS LE COUVERCLE (OU LE DOS). AUCUNE PIÈCE RÉPARABLE PAR L'UTILISATEUR À L'INTÉRIEUR. RÉFÉRER L'ENTRETIEN À UN PERSONNEL QUALIFIÉ.]

The lightning flash with arrowhead symbol [⚡] within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle [❗] is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

Earth symbol [?]: The apparatus shall be connected to a mains socket outlet with a protective earthing connection.

WARNING: DO NOT OPERATE THE BATTERY COMPARTMENT.

The remote control contains a button cell battery. If the battery compartment does not close securely, stop using the product and keep it away from children.

If batteries are swallowed, they can cause severe burns or death in as little as 2 hours. Seek immediate medical attention.

Remote Control Operation

The remote control duplicates the functions of the amplifier's front panel controls.

POWER BUTTON

Duplicates the Power Button on the front panel of the amplifier.

VOLUME

Duplicates the Volume dial on the front panel of the amplifier.

EQ Control

Low-Cut: Push to turn the Low-Cut Filter on/off. This filter reduces all frequencies below 25Hz (-3dB) at a rolloff rate of 12dB per octave.

High-Cut: Push to turn the High-Cut Filter on/off.

High Cut Hz: Use these buttons to set the High Cut Filter Frequency.

Amplifier Operation - Front Panel

Controls and indicators on the front panel (from left to right):

• POWER: Powers the amplifier on or off. The power indicator LED illuminates green when the amplifier is on and red when it is off or in standby mode (activated after ~20 minutes without signal).
• POWER STATUS INDICATOR (Red/Green LED): Red indicates Off mode or Standby mode. 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 all amplifier circuits are energized and ready to function. After 20 minutes of no input signal, the amplifier reverts to low power Standby mode.
• 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: Engages the low-cut filter, reducing frequencies below 25Hz (-3dB) at a rolloff rate of 12dB 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 filter, which rolls off higher frequencies (-3dB, rolloff rate of 12dB per octave).
• VOLUME: Displays the volume level (intensity) of the amplifier.
• VOLUME MINUS (-) & PLUS (+): Adjust the volume level (intensity) of the amplifier.
• POWER STATUS INDICATOR (Orange LED Fault Indicator): See page 11 for Fault Statuses and solutions.

Amplifier Operation - Rear Panel

Connections on the rear panel (from left to right):

• IEC TYPE POWER CORD RECEPTICAL: Attach one end of the 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.
• 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 the 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.
