Bluetooth Module Bypass Mode
Bluetooth module will be completely bypassed. Tone controls will not work in this
mode. This mode will result in slightly better audio quality and latency.
Outputs
Along with the typical speaker outputs on the KAB-2150 (2-channels), the amplifier also features an I2S
Digital Output and an Analog Line Output (not available in Bluetooth Bypass Mode) for connecting
powered subwoofers, cascading amplifiers, etc.
•
Speaker Output - The KAB-2150 has two speaker output, and are stable down to 4ohm,
which means it can power most speakers. This also means it can power impedances of
speakers greater than 4ohm, however the efficiency will go down as the impedance goes up.
Do not bridge the speaker outputs. This amplifier is not intended to be bridgeable.
•
I2S Output – The KAB-2150 has an I2S digital output, which can be useful for cascading
external amplifiers to the KAB-2150. For example, you could connect to the Bluetooth of the
KAB-2150 and use its two channels of output, but cascade another I2S amplifier and use the
KAB-2150's Bluetooth signal.
•
Analog Line Output – There is an analog output on the KAB-2150 as J30. Because it is
analog, this means that RCA jacks or an AUX jack can be directly wired to it as a line level
source to feed another amp (the KAB-2150 comes with an AUX jack harness that will plug
into this port). This could be useful to create a line output for feeding a subwoofer amplifier
to create a 2.1 system. This output does not work in Bluetooth bypass mode.
o This output is affected by tone controls and master volume control
o This output will work via a Bluetooth signal or an analog signal via J103BT_LineIN.
o This output will not work in Bluetooth Bypass Mode.
Out of the box, J103 will have a black jumper bridging the "KEY" and "BT_R" pins
on the J103 aux connector. Remove this to attach the aux port. However, it
must be replaced if you are not using the aux port. If you do not have the
jumper or the aux port in J103, Bluetooth will not connect.
Bluetooth will turn off once something is plugged into the aux port. To use
Bluetooth, the aux port must be empty.
The switch must be set to "BT_R" for this mode
– Bluetooth will not work in this mode, and the
