Rear Panel
1. BLUETOOTH ANTENNA
2. AUTO ON CONTROL
This is a handy feature when using the DTA-100ST in conjunction with other
audio equipment.
It will safely turn off the amp when audio stops and will turn it back on when audio
is detected. (please see pg. 6 for a more detailed explanation)
3. LINE INPUT (AUX)
4. PRE OUT
Stereo RCA jacks allow for connecting the DTA-100ST to other audio equipment.
This signal level is controlled by the volume knob and will output whatever input
is selected. It is not affected by the High Pass Filter (HPF).
5. HIGH PASS FILTER
This will help remove low frequencies from the connected speakers to protect
from high-excursion. This feature is also particularly handy when using an external
subwoofer so that the main speaker and subwoofer outputs do not affect each other.
6. SPEAKER OUTPUT
Using insulated 2 conductor wire to connect to speakers. The polarity, positive
(+), and negative (-) for all speaker and amplier connections must be consistent
so both the left and right speakers are in phase.
NOTE: The speaker outputs are not bridgeable.
7. AC POWER INPUT
The DTA-100ST is capable of operation in 110V and 220V regions. The internal
power supply will automatically sense the power input and operate appropriately.
8. MAIN POWER SWITCH
Turns the device on and off.

Connecting Speakers
The amplier can power speakers with a minimum impedance of 4Ω, using speakers with
a lower impedance can cause damage to the amplier. Use high quality two conductor
speaker wire and your choice of connector to connect your speakers to the binding posts
on the rear of the unit.
Connect the DTA-100ST’s left speaker terminals marked “L-” and “L+” to the corresponding
“-” and “+” terminals on your left speaker. Repeat the same process for the right channel.
NOTE:Never connect the negative terminals together or to ground. The DTA-100ST is not
designed to operate in a bridged mode and attempting to do so may damage the amplier.
Operation
Bluetooth Operation
When switching to the Bluetooth input, the indicator light will ash to indicate that the device
is ready to pair. If the last connected device is within range it will connect automatically.
Otherwise, look for the DTA-100ST in your device’s setup menu and initiate pairing.
The DTA-100ST will automatically disconnect after 15 minutes of silence and
enter standby.
AUTO ON Function
For ultimate control in any installation, the DTA-100ST has an auto sensing function that
can turn off the amplier when not in use and turn it back on when audio is detected.
When the DTA-100ST is in standby the power indicator will illuminate red. To activate this
function, toggle the AUTO ON switch. Otherwise, leave the switch in the ON position for
normal operation.
When using the AUX input, the DTA-100ST will enter standby after fteen minutes of
silence. The amplier will turn back on when music is played again. The power light will
change to white and the AUX input light will light up again. The DTA-100ST will remain in
standby until audio is sensed on the line inputs, or the front panel controls are used.
While using the Bluetooth input the DTA-100ST will unpair from the connected device after
fteen minutes of silence and enter standby. The power light will illuminate red and the
Bluetooth light will ash to indicate that pairing mode is active. The DTA-100ST will remain
in pairing mode until a Bluetooth device connects or the front panel controls are used.
