The Footcontroller MUTE switch activates the MUTE feature in both Front and Rear outputs simultaneously.
SLAVE: The SLAVE feature provides a padded signal that is derived from the Speaker Output and captures the entire sound of the preamp and power section. This is useful for large venue applications, where multiple BIG BLOCK or other slave amplifiers are
strung together for additional power to drive more speaker enclosures.
LEVEL SLAVE OUT
The SLAVE may also be used as a send signal to feed outboard processing racks in a dry/ wet setup where processing is done after the BIG BLOCK 750 and then fed to a Stereo power amplifier for separate control of the wet sound. This works very well and is similar to what is done in the recording environment where a dry
signal is blended with another channel on the console that is only the processed (wet) version of the same sound.
NOTE: Once a signal has been taken from the SLAVE, you can not feed the signal back into the BIG BLOCK Effects RETURN jack or INPUT. Doing so will cause a feedback loop resulting in a high pitched squeal, much like a microphone held up to a monitor. You must go into an external amplifier or device once a signal has been taken from the SLAVE.
NOTE: Always start with the SLAVE LEVEL at 7:00 (off) and increase the level slowly to prevent damage to ears, speakers and the input stage of external processors.
NOTE: The SLAVE is not optimized for direct interfacing into recording consoles or live mixing boards. For this application it is best to use the DIRECT OUT.
SPEAKERS: These two sets of outputs are responsible for delivering the mighty power of the BIG BLOCK to your speaker enclosure(s) of choice. We would like to suggest that if you have not already auditioned one of our many incredible new Bass Enclosures, that you do so at your earliest convenience. They have been designed to deliver the ultimate tone and maximum power from your amplifier and we feel confidant that like us, upon hearing them, you will find the competition disappointing.

OUTPUT
SUGGESTED LOAD
2 OHMS MINIMUM
Two styles of speaker connectors have been provided so that any type of cabinet configuration may be interfaced with the BIG BLOCK. NEUTRIK brand
Your BIG BLOCK was designed so that it will deliver its maximum power (750 watts RMS) at an impedance load of 2 Ohms and it can do so without worry of overheating. However, feel free to use any combination of cabinets with a combined load above that impedance with no worry of damage to the amplifier. At higher impedance loads (4 or 8 Ohms) overall power will be diminished, but this works out in your cabinets favor as some cabinets may not be rated to take the full assault of the awesome power available in the BIG BLOCK output section.
NOTE: It is possible to use the DIRECT OUT for recording direct to consoles with no load present (no Speaker cabinet connected) on the SPEAKER OUTPUT without worry of damaging the amplifier.
That covers the features of the BIG BLOCK Rear Panel, and now with the combined understanding of the controls, you should be able to dial with confidence as you search for your signature sound. We wish you many years of inspiration and musical fulfillment from your new amplifier. From the entire MESA Family, CHEERS!
