5) Phase Setting:

Use to correct subwoofer frequency arrival times. Can only use when in “Low Pass” setting.

7)Volume Setting:

Set based on the input level and power rating of your load.

4)Bypass/Lowpass: Set to Bypass to use as a 2 channel or 2.1 channel amplifier. Set to Lowpass to use as a 1 channel or subwoofer amplifier.

6)Crossover Setting: Room equalization for subwoofer frequencies. Can only use when in “Low Pass” setting.

B)Turn the phase knob to zero and place the meter in the listening position.

C)While the system is playing the 50Hz tone, read the meter.

D)Rotate the phase knob until the meter reads the highest possible.

E)Take note of the position for future reference.

6)Crossover Setting:

As a rule of thumb:

A)If you are powering the THOR In-Wall SUB10, the Q10B tactile transducer, or a large subwoofer (12” - 18”), set the crossover to 50Hz - 100Hz.

B)If you are powering a MQB-1 tactile transducer, a 10” subwoofer, or small front speakers, set the crossover to 70Hz, or the 9 o’clock position.

C)If you powering a small subwoofer (8”) or small speakers, set the crossover to 100Hz, or the 12 - 2 o’clock position.
