1. Gain - Sets the overall level of the amplifier, which is used to match the output of the

subwoofer to the rest of the speakers in the system. Gain adjustment does not affect line

out pass-through level.

2. Low Pass Frequency Adjustment - Adjusts the 24 dB/oct low-pass crossover

frequency from 30 Hz to 200 Hz. This adjustment will allow you to properly integrate

the subwoofer with main or satellite speakers. It is recommended to experiment with

different settings until the smoothest transition between subwoofer and speakers is

achieved. If you are using a source that already creates a low passed, line level (RCA)

subwoofer output (like a sub out jack on a receiver), it is important that you only use

the low pass filter adjustment on the receiver or on the DTA-100LF to avoid interaction

between these filters. If you choose to use your receiver's low pass filter adjustment, set

the FREQ knob on the DTA-100LF to its maximum setting of 200Hz.

3. Phase - The phase adjustment dial allows you to compensate for differences in

the acoustical and electrical characteristics between the subwoofer and the main

system speakers. The relative locations of speakers in the system can cause significant

disturbances in speaker interaction due to time delay issues, or the destructive phase

interferences that can occur at certain frequencies. Experimentation with this dial in

conjunction with altering the location of the subwoofer can dramatically improve

system integration.

4. Power LED - The amplifier can be turned on by either the main power switch or

AUTO ON. When the indicator LED is red, the amplifier is in standby mode. When the

LED is blue, the amplifier is fully active.

5. EQ - The EQ adjustment knobs enables you to custom-tailor one band of parametric

equalization for their subwoofer, which can be used to add boost to the low-end of the

response, or can be used to cut out an excessively loud room resonance. The FREQ knob

selects the frequency for the filter between 10 to 80 Hz. The bandwidth knob selects how

wide or narrow the filter is (the higher the bandwidth, the broader the effect). The level

knob can be used to add up to 5dB of boost or 11.5 dB of cut.
