Connections
Input - Using a stereo or mono RCA cable, connect the LFE OUT, Sub OUT or
other line level audio output to the DTA-100LF's LINE IN. Since the LINE OUT
sends a full range audio output and is not affected by the built in EQ, crossover,
or subsonic filter, the DTA-100LF can be placed either before or after a full range
amplifier or powered speakers.
Output - Using 16AWG (minimum) 2-conductor stranded speaker wire, strip
approximately 1/2" of shielding from each end and twist together so that there
are no loose strands that can cause shorts and damage the amplifier. With the
amplifier powered off connect the prepared wire to the appropriate + and -
terminals on both the amplifier and an unpowered subwoofer. Verify that the
amp and subwoofer are connected using the same polarity to experience the full
power of the DTA-100LF.
Operation
Power - To power on the DTA-100LF toggle the POWER ON/OFF switch. If the
AUTO-ON switch is ON the amplifier will begin working immediately.
Automatic Power Sensing - For ultimate control in any installation the internal
amplifier has three different power settings. When set to "OFF" the amplifier will
remain in STANDBY, but audio will still be pass to the "LINE OUT". When set to
AUTO (middle position) the amplifier can sense 8 mV signals on the RCA line-
level inputs and automatically switch the amplifier from STANDBY to ON. The
Amplifier will automatically return to STANDBY when no audio has been detected
for fifteen minutes. When set to "ON" the amplifier will remain on and will not
enter STANDBY.
Crossover - The low pass filter adjustment sets the frequency at which audio
content will pass to the DTA-100LF Speaker Output. A low pass filter means that
the frequencies below the target frequency will be unaffected, and the higher
frequencies will be removed. Removing higher frequencies will allow the amplifier
and connected subwoofer to produce clear distortion-free audio. Adjust the low
pass filter frequency between 30 Hz to 200 Hz so there is a natural sounding
transition from the main speakers and the connected subwoofer. This value will
change depending on the size of the speakers and subwoofer being used.
Phase - The phase setting is used to compensate for the subwoofer's location
relative to the main speakers, and create a smoother transition from the main
speakers to the connected subwoofer.
