Connection and operation of the ADA120 is simple and straight forward. Please read the
following instructions prior to powering on and connecting your amplifier to speakers.
1. Power LED.
Blue LED indicates the unit is receiving power and is fully operational.
2. Power / Volume control.
This control turns on the unit and adjusts the volume
level of the amplifier. When the unit is turned on the power LED will become fully
illuminated. To turn the unit off, turn the control fully counter clockwise until it
“clicks” to the off position. It is normal for the power LED to slowly dim and then go
completely out when the unit is first turned off.
3. Headphone Jack.
The ADA-120 also doubles as a headphone amplifier that
will drive any headphone easily and delivers colossal sound stage and effortless
dynamic range. The 1/4” stereo jack allows connection of larger home and studio-
style headphones. An adapter is available so that smaller 3.5 mm personnel
style headphones can be used. Note: When headphones are plugged into the
headphone jack the speaker output connections are disconnected.
4. 3.5 mm Audio Input.
The unit features a convenient front mounted 3.5 mm stereo
input for quick connection of iPods, MP3 players, and other portable audio devices.
Note: When a device is plugged into the 3.5 mm audio input the rear mounted RCA
input jacks are disconnected. This allows the user to permanently connect a device
to the rear RCA audio inputs and switch to a portable device by simply plugging into
the front mounted input.
5. Power Connection.
The ADA-120 operates on 24VDC and MUST be used with a
power supply that can provide at least 5A. A world compatible (100V-240V) switch
mode power supply is included with the unit. The power connection on the unit is a
2.5mm x 5.5mm jack with center pin being positive. Note: If an inappropriate power
supply is used and the unit is damaged, the warranty will be voided.
6. Speaker Outputs.
The speaker output connections utilize high current binding
posts that are spaced on 4mm centers and are compatible with standard double
banana plug connectors (sold separately). The connections are colour coded for
easy polarity identification. Screw-on connectors will accept 10AWG-18AWG.
7. RCA-Type Audio Input.
RCA-type line level input for permanent connection of
larger devices such as CD players, PCs, and DVD players. An RCA to 3.5 mm
adapter is available for added connection flexibility. Note: When a device is plugged
into the front mounted 3.5 mm input, the RCA input jacks are disconnected.
