MicroBass-III Series

Safety Information

Please read all enclosed safety precautions, before connecting or operating this product.

Verify Line Voltage and Amperage Before Use:

Your new MicroBass Series amplifier has been factory configured for use with:

120 Volt/60Hz 15 A circuit for USA/Canada.

230 Volt/50Hz 10 A circuit for UK/Australia.

240 Volt/50Hz 10 A circuit for Europe.

100 Volt/50Hz 15 A circuit for Japan.

220 Volt/50Hz 10 A circuit for Korea.

Connecting the amplifier to a line with specifications other than indicated above can create a safety or fire hazard and may damage the amplifier. If you have any questions about the voltage requirements for your specific model, or about the line voltage in your area, contact your dealer before plugging the unit into a wall outlet.

Verify AC Circuit Capacity Before Use:

The high power output of your amplifier may require heavy current draw under full-load conditions. To insure proper performance and avoid potential safety hazards, we recommend connection to line circuits with amperage specified “as above”. Connecting multiple amplifiers to the same circuit, or connecting the amplifier to the same circuit used by other heavy-power devices, such as high-wattage lights, may cause circuit breakers to trip. It is always a good idea to avoid using any audio equipment on the same AC circuit as equipment with motors, such as air conditioners or refrigerators. This will lessen the possibility of power variation and electrical start-up noise affecting your sound.

AC Power Cord:

To avoid safety hazards, use only the power cord supplied with your unit. If a replacement cord is needed, make certain that to use a standard IEC compliant cord. Damaged power cords should be replaced immediately.

Connecting to AC Power:

When setting up, make certain that the AC plug is easily accessible. If mounting in a rack, ensure that the AC mains can be easily disconnected by a plug or by an all-pole disconnect switch on or near the rack.

Disconnect When Not In Use:

If you do not intend to use the amplifier for a considerable length of time, disconnect the plug from the AC outlet. Just switching the unit off does not mean that it is fully disconnected from the AC Mains. To isolate the unit from the AC mains, you must disconnect the power cord from the unit and the AC outlet. When disconnecting the power cord always pull from the plug, never pull from the cord.

Do Not Open the Amplifier Enclosure:

There are no user-serviceable components inside this product. Opening the amplifier enclosure may present a shock hazard, and modification to the product will void your warranty. If liquid enters the unit, or any metal object such as a paper clip, wire, or staple accidentally falls inside the enclosure, disconnect the unit from the AC power source immediately and consult an authorized service station.

Unpacking:

The carton and packing materials used in shipping your new amplifier were specifically designed to cushion it from the shocks and vibration that occur during transport. We suggest that you save the carton and packing materials for use in shipping, in the event you move, or the amplifier needs repair.

MicroBass-III Series

GK Philosophy

I have never seen the point in doing things the way others have done them. I also have not been very interested in following the latest fad. I am a Stanford educated engineer who worked his way through school as a musician. Like all musicians, I have lugged amplifiers up stairways and into car trunks, always wondering why these things had to be so heavy, bulky, and hard to handle.

As I am the principal innovator at GK, our products reflect my attitudes and life experiences. I don’t model my designs after other manufacturer’s products (as some of our competitors are proud of reciting). Instead, I believe new and old problems are best solved with new solutions. Having taken our own path, GK products enjoy a unique, unmatched sound, allowing the artist using them every opportunity to make an original statement.

Having supported my products for over thirty years, I have learned from the story they tell. Gal- lien-Krueger is a reflection of that story, and has a commitment to support that legacy. Just as the products I created thirty years ago are still telling their story, the products we create today will be talking to us tomorrow.

If your MB Series amplifier or combo is missing any items, or if you encounter problems while setting up your new equipment, please contact your local dealer, or us as soon as possible at:
