My amplifier will not power on
1. Ensure that your DC power supply is within the specified voltage range required for the amplifier
and is making good contact.
2. Ensure that your DC power supply is a center positive power supply to match the DC jack
included with the amplifier.
3. With power removed, carefully look over the board for any visibly damaged components. If any
are found, do not plug the amplifier back in.
4. If you have a standby switch connected, toggle the switch. If your switch is working backwards,
such that turning the switch off turns the amplifier on, with many switches you could swap the
wire connections to the switch to change the behaviour of the switch
5. Make sure that there are no wires touching that should not be, such as speaker wires shorted
together. Make sure that nothing is on top of the amplifier, like a loose screw or nut.
I have connected my speakers, but I'm not getting any sound
1. Make sure your KAB-2150 is set in the appropriate input mode using the on-board switch and
you have connected your AUX jack to the correct port. If using Bluetooth, make sure you have
the jumper inserted into J103 (see Input Modes above). Without this jumper, Bluetooth will not
connect.
2. Check your audio source is working properly, such as a phone, laptop, etc. Try a different audio
app on your phone to make sure it is not the current app that is having problems.
3. Check the wiring of your speakers. Carefully follow the + and – signals labelled on the board and
on your speakers, and make sure they are making good connection.
4. Check the volume level of your audio source. If using a streaming service, make sure audio is
actually streaming and the service is not buffering or stalled.
5. If using Bluetooth, make sure you are connected to DAKAB. If you have multiple Dayton Audio
amplifiers, make sure you are connected to the correct DAKAB Bluetooth Signal.
I cannot connect to the device's Bluetooth
1. Check that your amplifier is powered on and not in standby mode.
2. Try restarting the device you are trying to connect to the amplifier, such as a phone or laptop.
3. Decrease the distance between the amplifier and the Bluetooth audio source
4. Attach any included antennas to your amplifier. If you built your amplifier into a metal case, this
antenna will need to be externally located in most cases.
5. Attach the pairing button to the amplifier and hold it for 2-3 seconds to unpair any previously
paired devices. The amplifier might already be attached to a different Bluetooth device. Do not
hold the button down for longer than 5 seconds.
6. Remove all power from the amplifier board for at least 10 seconds and then repower it
7. If the board originally came with a jumper/jumpers that you removed when installing a volume
control or line input plug, reinstall the jumper according to this guide.
8. Try a different Bluetooth source device to ensure that is not the problem.
9. Make sure your device is not in standby from an attached standby switch.
