(Please note: If you intend to use the

BA260, BA460, BA2100 AND BA2150

in the Tri-mode

configuration, it is necessary to set the crossover control to the “FLAT” setting in order to
receive full range output)

The “BA” amplifiers are equipped with a built-in crossover network allowing you to select
the crossover type (i.e. Low-Pass or Hi-Pass) and the desired crossover point. For example
if you wish to drive a pair of subwoofers, you can select the “Low Pass” setting on the

amplifier to filter out high frequencies. This will send only low frequencies to your
subwoofers (see example settings below).

Select the crossover type on the

amplifiers side panel.

(Low-pass is selected in this example for subwoofers)

You can add up to 12dB bass boost by

increasing the Bass Boost control.

Select the crossover

point for your speakers.

DJUSTING THE X-OVER AND BASS

Fine tune the amplifier's input sensitivity.

T h e g a i n s e n s i t i v i t y c o n t r o l f o r t h e “ B A ”

amplifier is located on the side panel. This gain control

has been included to allow adjustment to properly

match the output of the radio. This is one of the most

misunderstood adjustments. By rotating the control in

the clockwise direction, the amplifier‘s input will

become more sensitive and the music will play louder. This is

not a volume control and you will not get more power out of the amplifier in the maximum

position! It may seem to deliver more output, but actually the system is only playing louder

faster as you turn the volume control on the radio. Ideally, to properly level match the

system the goal is to achieve maximum output from the amplifier without distortion at

about 3/4 of the volume control.

To determine if the amplifier’s gain is set properly, turn the system on and slowly increase

the volume control. You should be able to use about 3/4 volume before the system gets loud

but not distorting. It is very important when making these adjustments that you do not

over drive the speakers (at point of distortion) this will cause permanent damage to the

speakers. If you are unable to achieve 3/4 volume before distortion you will need to

adjust gain control (in this case you would reduce the gain). The gain controls should be

adjusted very slowly. It may help to have another person to assist you by adjusting the

gain controls while you listen for distortion.
