Genesis servo-bass amplifiers



My question is directed at owners (past or present) of the following Genesis models: 1.1, 201, 350, & 350SE.

Have any of you experienced problems with the bass amp shutting down due to transient overloads?

The bass amps included with these speakers have a protection circuit which may trip due to either a transient or thermal overload. Each failure mode is described below:

Transient Overload:
- Amplifier runs cool to warm to the touch but protection circuit trips excessively
- Often occurs with electronic music (e.g. rap/hip hop) on particular tracks only
- Amp will immediately turn back on but may trip again moments later
- Minor reductions in volume (-3dB) typically have no effect (amp will still trip)

Thermal Overload:
- Amplifier runs hot to the touch during heavy use and protection circuit trips
- Amp will not turn back on until it cools down (may take up to 30 minutes)

I'm wondering if anyone else has experienced the transient overload case, and if they've found a way to eliminate it.

I understand that the thermal overload case means the amplifier is at maximum power, and the only way to fix it is to turn the volume down.

No, not a hiccup in 2 years. I'm running at a 65 setting and often play really loud and I've never felt the amp get warm. Probably something wrong with the bias adjustment or a bad output transistor. Do a search and find a good tech because GAT charges a first born.
Hi Ngjockey,

Which Genesis model do you have?

Do you listen to a lot of electronic music (i.e bass from computers, not real instruments)?

Thanks for the response,

350's with BG ribbons and 1600W amp.

There's your problem, the electronic "music" ;)
What bass cables are you using? I had several problems with my bass towers when using the older audioquest cables from the bass amp to the bass towers. Several times through any music I would even see the woofers bounce in and out in an awkward fasion. If you do have the older cables I would suggest you upgrade them.
