ButtKicker BKA1000-4A - Power Amplifier 120 volt version Manual

Front Panel Controls

Power Switch

The Power Switch connects the AC line to the amplifier circuits. Check the amplifier connections and verify the AC line power source before engaging the Power Switch.

Power Light

Red indicates presence of AC power, but no signal. Green indicates presence of both AC power and signal; power is applied to all the amplifier circuits and the amplifier is ready to operate. After 20 minutes of no input signal the amplifier will revert to a low power Standby condition.

Filters

Low Cutoff Switch

Switches the Low Cutoff Filter in and out of the circuit. The filter's slope is set at 12dB per octave.

With the Low Cutoff in the ON position, frequencies lower than 25 Hz are filtered out. This is ideal for musicians who do not need nor want the ButtKicker to respond to any frequencies below 25 Hz.

When the Low Cutoff is in the OFF position frequencies below 25 Hz are passed on to the ButtKicker. This is ideal for home theater use and the low frequency response the ButtKicker has become known for.

High Cutoff Switch

Switches the High Cutoff Filter in and out of the circuit. The filter's slope is set at 12dB per octave.

With the High Cutoff in the ON position, frequencies above 40 Hz to 160 Hz are filtered out - only frequencies below 40 Hz to 160 Hz are passed to the ButtKicker based on the position of the High Cutoff Frequency control.

This is ideal for home theater use when only low frequencies are wanted. Conversely, when used by musicians, leaving the high cutoff switch in the OFF position enables the ButtKicker to respond to all frequencies in its natural working range of 5 - 200 Hz.

High Cutoff Frequency Control

Controls the frequency at which the High Cutoff circuit begins its filter action. The Variable High Cutoff Frequency control allows you to set the high cutoff frequency from 40 Hz to 160 Hz.

Volume Control

Controls the output level. Set this to balance the ButtKickers with the sound system when using the amplifier to power ButtKickers.

Rear Panel Controls

Line level Input

RCA / phono jack. This input should be used for the preamp output of a consumer home theater surround processor or stereo preamp with nominal signal levels of 160mVolt.

High Level Input

1/4 / phone jack. This balanced, TRS input should be used for professional level outputs; i.e. mixing consoles and other equipment with nominal signal levels of 1.25Volt (+4dBu).

Speaker Output Binding Posts

Power amplifier bridged output. Used for attaching speaker wire to the ButtKicker or other speakers. Turn the amplifier off before connecting to the Speaker Output. Wire sizes of 14 gauge and larger are recommended. Binding posts will accept banana type connectors.

Power Connector

Used to connect the supplied power cable to the amplifier.

You must use the supplied cable to avoid potential safety hazards. Also, for added protection, the amplifier may be plugged into a surge protector, rather than directly into the 120v outlet. Use of a non-grounded power cable or defeating the supplied grounded (3 prong) cable will void the warranty and may cause electrocution.

Fuse Holder (integrated into Power Connector)

Fuse: T15AL 250V for 120V 50/60Hz AC input. A spare fuse is also contained in fuse holder for your convenience and is located immediately below the power cord outlet on the rear panel (see Photo).

Helpful Hints / Troubleshooting

The amplifier has no output

The amplifier has both thermal and output protection circuits. The amplifier is designed to disconnect power from its output terminals when an unsafe condition exists to protect the amplifier and whatever is connected to the amplifier's output. To reset the amplifier; turn the amplifier to the off position (power switch down; no red or green light will be visible), unplug the power cable from the electrical outlet, verify proper output wiring and adequate ventilation for the amplifier, re-plug the power cable to the electrical outlet, then turn the amplifier to the on position.

There is a hum in the sound system when the amplifier is connected

This can be caused in certain circumstances when a sound system has two separate contacts with earth ground. This is usually caused when a cable TV feed is connected to the TV which is then connected to the sound system. This condition can be verified by disconnecting the cable from the TV (eliminating one of the grounds) and playing a DVD or CD to verify the proper operation of the ButtKicker. If disconnecting the cable TV solves the problem, then using an inline ground isolator is recommended. Visit www.thebuttkicker.com for more information or contact an electronics retailer. PLEASE NOTE that if you are using the ButtKicker Wireless Link, a hum will never be the effect of a ground loop. If you experience a hum while you are using the Link, disconnect the Receive unit from the wall and the amplifier for 10 seconds; then reconnect. This will reset the Link and may eliminate the hum.

PLEASE allow two inches (5 cm.) of clearance around the amplifier on all sides for proper ventilation.

The BKA1000-4A will power two 4-ohm ButtKicker LFEs when wired in parallel. However, there is more heat generated by the amplifier in this situation, so please allow extra ventilation space for the amplifier. Three or four ButtKicker LFEs may also be powered by using the BK-QCP or by following the wiring instructions in the FAQ section of our website.
