5) Phase Setting:
Use to correct subwoofer
frequency arrival times.
Can only be used when in
“LOWPASS” setting.
7) Volume Setting:
Set based on the input
level and power rating of
your load.
To set the phase:
A) Send a 50Hz continuous tone signal through the speakers and the
subwoofer at the same time.
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.
7) Volume Setting:
Always start at MIN position and slowly increase the volume to reach
the desired sound level.
6) Crossover Setting:
Sets the 3dB down maximum
frequency range. Note that the
amplifier must be set to “LOWPASS”
for this feature to work.
