MINI AMPLIFIER

Model: DA30 User Manual

The Dayton Audio

DA30 is the ideal ampliﬁer for commercial audio installations; such as classrooms, where a small, low wattage

ampliﬁer is required. This Class D ampliﬁer can sit on a desktop, or can be mounted on a wall or under cabinets using the included

mounting brackets. In stereo mode the DA30 delivers 2 X 15 W and in bridged mode 1 X 30 W. Two stereo audio inputs increase

versatility; 2-RCA or a single 3.5mm jack. Separate Treble and Bass controls allow the sound to be tailored to the room. The DA30’s

Auto-On feature means the unit will not sit idle wasting power when not in use.

CONNECTION

(1) Set the MODE switch to Bridge Mono or Stereo

(2) Connect your Speakers using the detachable “Phoenix” connector

(2a) For stereo operation connect the Left and Right speaker wires to the corresponding terminals

(2b) For bridge-mono operation connect the positive speaker wire to the L+ and the negative speaker wire to the R+ terminals

(3) Connect a source device to the INPUT terminals; 3.5 or RCA*

(3a) 3.5mm male plug to the 3.5mm jack

(3b) 2-RCA plugs to the two RCA jacks

(4) Connect the power supply to the 12 VDC input

*NOTE: When connected, the 3.5mm input will override the RCA inputs.

OPERATION

Once input and output connections are made it is time to use the DA30.

●Press the POWER button to turn on the ampliﬁer. A green LED indicator shows the ampliﬁer is ready to use, a red LED indicator

shows the ampliﬁer is in the “Auto-On” state to conserve power.

●Turn on the source device and set the source output level. A green LED indicator shows the ampliﬁer is ready to use, a red LED

indicator shows the ampliﬁer is in the “Auto-On” state to conserve power.

●Adjust the VOLUME on the DA30 using the rotary volume control; turning clock-wise will increase the volume level.

●Adjust the BASS and TREBLE to set the audio to a more realistic tone using a small ﬂat-blade screwdriver.

●Adjust the BALANCE so the sound is evenly distributed through the room using a small ﬂat-blade screwdriver.

After 10 minutes of inactivity the DA30 will go into the “Auto-On” state.

mounting to a desktop, ﬁrst remove the feet from the bottom of the ampliﬁer and discard.

TROUBLESHOOTING

If the DA30 does not turn on with a source connected and playing try these troubleshooting tips:

●Does the source device have a 3.5mm output (such as a PC or laptop)? Connect headphones to the headphone jack and

check for an output signal.

●Does the source device have RCA line output (such as a DVD player)? Connect a known working ampliﬁer and speakers to the

line outputs to check for a signal. Refer to the DVD player manual to switch output to L&R stereo line level if necessary.

●Check the power switch, when depressed the DA30 is in “auto-on” mode and the power indicator should be lit.

●Check the power supply; verify it is plugged into a working receptacle and is ﬁrmly plugged into the 24 VDC power jack.
