Connecting ButtKicker low frequency audio transducers to your A/V Receiver

The amplifier driving your ButtKicker transducer(s) needs to have a signal source, we recommend using your AV Receiver's "Subwoofer Output" (which will include the .1 or LFE channel, and possibly the low frequencies of all the other channels).If a subwoofer is currently connected to the Subwoofer Output an RCA "Y" splitter can be used to run the one signal to both the subwoofer and the BKA1000.

Please consult your ButtKicker product manual and/or Quick Start Guide for detailed instructions.

If your A/V receiver uses speaker wire connections for the subwoofers and/or speakers you can use the Speaker Level Interface Adapter to connect to the receiver. The Speaker Level Interface Adapter connects to the subwoofer output at one end with speaker wire and leads into an RCA "male" jack at the opposite end.

If your A/V receiver does not have a subwoofer output (because of a proprietary cable being used for the subwoofer) you can still connect the center channel speaker or other speakers. In this case ensure that low frequency sound is being sent through the selected channel so that the ButtKicker transducer receives signal. If a speaker channel is unavailable some A/V receivers may have a line level output to connect to. If no such connections are present (this occasionally occurs on low-end "home theater in a box" type systems) there is unfortunately no way to connect to the A/V receiver. In this case please contact the manufacturer for suggestions on connecting external audio devices.

I get a "buzz" or "hum" from my speakers now. It's always there, even if the sound is turned all the way down. What's my problem?

Your home theater system has developed a "Ground Loop" which is caused by having more than one ground connection in the system. Most likely, your cable TV combined with the ground of the ButtKicker power amplifier power cord is causing interference in the audio system. Any other electronic device with a grounded power plug might cause the problem as well.

You can eliminate the problem in your system by adding a "RCA Ground Loop Isolator". Plug one end of the ground loop isolator into the RCA input on the back of the ButtKicker power amplifier and then plug the RCA cable coming from your A/V processor into the other end of the ground loop isolator.

I have my ButtKicker power amplifier turned up all the way, but I want even more intensity! How do I do this?

Most A/V processors have an option to increase the output from the subwoofer channel. Turn up this output to get more audio signal to the ButtKicker Power Amplifier. This may require you to turn down the volume of your subwoofer so that it is balanced with the rest of your system.

My floor is carpeted. Do I really need to use the rubber isolators?

Yes! The isolators will not only maximize the effect of your ButtKicker transducer(s), they are also important to support and level your couch and to make sure that the effect is contained within the couch.

Information For Drummers

The following are considerations when using a ButtKicker low frequency audio transducer with your kit. The ButtKicker Concert series is recommended for use by bass players, drummers and other musicians.

ButtKicker Concert Mounting:
When mounted directly to the throne seat, the ButtKicker Concert will of course deliver the most direct kick, but some thrones' seats are too small for direct mounting of the ButtKicker unit. A small platform isolated from the floor with rubber feet can be constructed on which the ButtKicker unit is mounted and the throne is set.

Signal Source:
A large factor on the signal is kick drum head tuning (loose vs. tight; low vs. high, etc.). You do not change your playing habits or drum tuning in order to advantage of the ButtKicker transducer.

A tap off the kick drum mic signal used by the sound system can be taken for the ButtKicker transducers's feed.

Pickups / Triggers:
The pickup's position on the head is a large factor on both the level and frequency content of the output signal.

A pre-fader aux send can be used to send a signal to the ButtKicker Concert. This allows a mix of whatever drum mics you want to feel, though most other drums may have little usable program content within the ButtKicker Concert's range.

Signal Processing:
No signal processing is necessary to energize the ButtKicker Concert, but some circumstances may warrant extra measures.

If the signal contains a lot of "garbage" between beats from other picked up stage noises, you may want to gate the signal. (Compliments of Jeff Kathan, drummer for the Paul Rodgers band)

Your kick drum signal could easily include infrasonic (below the hearing range) signals which are not relevant to your need and could cause excessive excursion within the ButtKicker Concert. This is not damaging, but it could result in lack of control, and the possible missing of complete beats. These infrasonic signals are influenced by head tuning, other sound sources in close proximity, etc. Eliminate the infrasonic signals by passing them through a Hi-Pass filter.

Missing a beat? ...especially on the hard beats? See "Signal Processing, Hi-Pass".

As always, your feedback is welcomed by us, and considered important to us.

How to Determine How Many Isolators You Will Need

Isolators come in different weight capacities.

All isolators are designed to be partially compressed in application and therefore, numerous models are made with varying weight specifications. This specification (, RDB-120, RDB-220 RDB-375)indicates the amount of weight (in lbs.) that each isolator is designed to support (per isolator) for greatest efficiency.

Calculate the total weight to be carried by the isolator, including platform, chairs and people. Divide this weight by the total number of isolator feet to be used (i.e. a minimum of 3, a usual number of 4, more when necessary). This will give you the weight per isolator. Pick the isolator model closest to your calculated weight. Enjoy!

Are there Any Current Product Recalls?

There are no current recalls at this time.

A recall was issued a number of years ago for the BKA-1000 amplifier for this serial number range:
BKA1000-4A-A0005570 --- BKA1000-4A-A0005815

What is a ButtKicker low frequency audio transducer and how is it different than other devices?

ButtKicker brand low frequency audio transducers utilize a patented magnetic suspension which is different from any other speaker or shaker and can be used couches, theater seating, platforms, and any type of structure. ButtKicker transducers accurately reproduce the "feeling" range of many natural and man-made sounds, such as earthquakes, thunderstorms, rocket launches, waves, explosions, tornadoes, volcanoes, dinosaurs, sound effects and all styles of music.

Different from other shakers or tactile transducers that use voice coil technology, ButtKicker transducers are much more powerful, more musical (linear) and offer true infrasonic or low frequency response with their resonant frequency of 9 Hz and range of 5 - 200 Hz.

One ButtKicker transducer will easily replace 2 - 4 or more of the other types of shakers previously available, and perhaps more importantly; it is virtually indestructible and maintenance free.

If you are looking to delight and electrify yourself and others with an affordable and easy to use solution, now is the time to incorporate ButtKicker brand low frequency audio transducers into your design and to "Feel what you've been missing!"

How Do I Know What Will shake?

The ButtKicker is an excellent low frequency transducer, but what it drives (your platform/floor/furniture) will have a direct influence on the total system response. Good low frequency response is a combination of both the ButtKicker transducer and the surface/platform driven by the ButtKicker transducer. The platform, whether it is a suspended wood floor, or a platform built under your furniture, needs to be able to move/shake at low frequencies. A tight (usually small) platform may vibrate freely at higher or midrange frequencies but not have the freedom to move for the low frequencies.

Considerations for Home Theater Risers & Platforms

Many home theaters have more than one row of seats, with the second and third rows being built upon risers. These risers, for ButtKicker transducer applications, have two purposes; raise and support the seats and occupants, and allow vertical platform and seat movement.

Height for the ButtKicker brand transducer:

ButtKicker brand transducers can be mounted above or below the top surface of the riser. If above, consider people traffic, furniture placement. If under the surface, some simple framing can be done to avoid the extra room needed under the riser. As always, keep in mind any maintenance that may become necessary.

Think "suspension."

In essence, you're constructing a floor above the room's floor. Build the riser similar to a suspended wood joist floor to give the riser its greatest low frequency response.

The major differences between a riser and real floors are the suspension points and tie points (to other external structure). The riser should be free floating (not tied into any adjacent walls), and suspended by short sides only. Use vibration isolators on the short dimension to support the riser from the room floor.

The greatest flex of the riser will be along its long dimension, the riser's short dimension will offer much less low frequency flexibility. Therefore, when possible, avoid any support along the long dimension.

Just How Much Power Can the ButtKicker brand Transducer Handle?

Each transducer has a specificed maximum and minimum power handling (RMS values). Unlike conventional voice-coils underpowering or overpowering a ButtKicker transducer will not cause permanent damage. However, greatly over-powering a ButtKicker transducer will cause the intergrated thermal switch (75C) to trip and the unit will need to cool before operation resumes.
