You may obtain a copy of the BB-50 Speakercraft Manual here:

As you can see from the diagram on PDF page 5, there are no termination points for the Speakercraft MKP or MODE keypads (which is what I assume what you are asking about when you say "Controllers for MZC-66")

There are however four independent methods for remotely powering your BB-50 on.

· Video Signal

· Audio Signal

· Powering up another device that is plugged into the BB-50

· Sending the DBB-50 and DC or AC trigger voltage.

These are described on PDF page 9. You need to set some toggle switches on the rear of the unit to get the desired effect.

Buzzing in speakers on Carlsbro Marlin 8400 Power Amp


If your volume is down and there's a hum, then it could be that your capacitors in the power supply are blown. Also there could be a problem with the bridge rectifier, possible that there's 1 or more diode's defect. Any technician can reapir that.

Hope it helps,
