INSTALLATION
OPERATION
SET-UP FEATURES
The MB Quart R Series amplifier offers a wide range of selections for the user to create a listening
environment that meets your personal preference.
Before making final adjustments, read through the descriptions for each feature to get the best results.
ADJUSTMENTS
Loosen the allen screw holding the small cover in place over the controls. Tilt
the cover up and away from the amplifier. After making adjustments, always
ensure the cover is in place to prevent accidental changes to the settings.
NOTE: Failure to follow these instructions may result in a loss of sonic
quality. This is caused by premature activation of the protection
circuitry to maintain the integrity of the amplifiers sensitive
components. The performance specifications listed in this manual
cannot be guaranteed under such conditions.
FRONT END DEFEAT
The front-end defeat switch is responsible for rerouting the signal around the signal processing circuitry
within the amplifier. This feature was designed for use with external processors to provide the purest possible
signal path through the amplifier.
With this configuration, the MB Quart R Series amplifiers are able to provide lower distortion and better
signal reproduction due to the reduction in the number of components in the signal path. Bypassing the
crossover will also eliminate the typical phase shift associated with the analog filter transform function. While
the Front End Bypass is turned on, all adjustments made to the gain or crossover will be bypassed.
