OPERATION

SET-UP FEATURES

The MB Quart Q 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.

R.E.A.D. (Realtime Electronic Amplifier Display)

The READ display gives the user a visual detailed status of all the settings on the amplifier. You can use the SELECT button to scroll though these settings without causing any changes.

Also, making changes to any of the settings will immediately be shown on the READ display.

EXAMPLE: Turning the adjustment wheel for the LEFT X.OVER will bring up the display for the left crossover. Also, the LED below the adjustment wheel will light showing that an adjustment is being made to that setting.

ADJUSTMENTS

Loosen the phillips 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 needed to maintain the integrity of the amplifiers sensitive components. The performance specifications listed in this manual cannot be guaranteed under such conditions.

LOAD IMPEDANCE

This optimizes the output section to match the speaker impedance. With the switch in the up position, the impedance is set to 4 (ohms). With the switch in the down position, the impedance is set to 2 (ohms). The setting on this switch should match the impedance of the speakers connected to the amplifier. Failure to do so may cause damage to the speakers and/or amplifier.

FRONT END BYPASS

The front-end bypass 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 Q 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, the READ display will not report the gain or crossover values and any adjustments made to these settings will cause the unit to display “Front End is bypassed!”.

CROSSOVER (X.Over)

Frequency Switch

Placing the switch in the HP position (Up) sets the amplifier to the High Pass mode, enabling frequencies above the cut-off point to pass.

Placing the switch in the LP position (Center) sets the amplifier to the Low Pass mode, enabling frequencies below the cut-off point to pass.

Placing the switch in the AP position (Down) sets the amplifier to the All Pass mode,

preventing any crossover adjustment, allowing all frequencies to pass. Adjustments made to the Multiplier switch or Adjustment Wheel will cause the unit to display the frequency setting as “N/A”.
