Phase adjustment- 0˚ to 180˚
This control allows you to "delay" the phase of the subwoofer's output
signal up to 180˚ to correct for any possible mismatch & resulting
cancellation between the subwoofer and your main speakers/amplifier.
To adjust, simply listen to the system with music playing. Then rotate the
knob from one end to the other and listen for a change in low frequency
output. The correct position will have a greater amount of apparent low
frequency output.
Auto turn on function
With this function in the "auto" position, your CHT-15 can be safely left
with the main power switch on continuously. The subwoofer will turn
itself on automatically when an audio signal is present. If no signal is
present for approximately 10 minutes, the unit will switch to standby
mode. While in standy mode, your subwoofer will draw very minimal
power. This function can be disabled by leaving the switch in the "on"
position.
High pass crossover switch
This switch selects the frequency for the high pass crossover. This
crossover is functional on both line-level and speaker-level outputs.
Smaller speakers with limited low frequency output may prefer the higher
100Hz setting which will reduce the low frequencies sent to them. Larger
speakers with greater low frequency output may be able to handle the 80Hz
setting without strain.
Power switch
The master power switch is located on the right half of the unit. This rocker
style switch is the main on/off for the unit. This switch should be set to
position 1 for on (up), 0 for off (down).
Line-level connection
Figure 1, on page 5, shows connection to a pre-amplifier's main outputs
and returning them to your amplifier inputs.
When installed in this fashion, your satellite speakers will be crossed over
at 80/100Hz which removes the lower bass from your amplifier and
speakers, enabling them to do a better job reproducing high frequencies.
