Speaker- and Audio-Connections: MXB280 / MXB2175
Speakers (Right) 2 - 8 Ohms
Speakers (Left) 2 - 8 Ohms
Connect the RCA cables
from the head-unit with
the RCA inputs
(LINE LEVEL INPUT).
2-Channel Stereo-Mode
Connect the RCA INPUTS of the amplifier to the head unit line outputs with appropriate
RCA cables. If your head unit is not equipped with pre-amplifier RCA line outputs you
can use the optional HI INPUTS (Highlevel Inputs). Connect therefore the speaker outputs of your
head unit with the enclosed cable plug. Check the Wiring Diagram below.
Connect the speakers with the speaker ouputs (SPEAKERS/ + L - and + R -) of the amplifier by
using appropriate cables.
Ensure that the total speaker impedance load is not lower than 2 Ohms per channel.
Too low speaker loads result in too high heat development and may cause the amplifier run into
protection.
FILTER - selector
If larger speakers (> Ø20 cm) are used, the position FLAT is recommended. A fullrange signal will be provided to the speakers.
For all smaller speakers (Ø8.7cm - Ø16cm) the position HIGH PASS is recommended, thereby the lower frequencies will eliminated
in the audiosignal. Set the cut-off frequency between 60Hz - 150Hz, depending of the size of the installed speakers.
The cut-off frequency is adjustable with the HIGH PASS controller. In this configuration the LOW PASS - controller is not used.
INPUT LEVEL - controller
• Turn the INPUT LEVEL controller on the amplifier to 4V position.
• Turn the head unit volume controller to about 80-90% of its full setting.
• Turn the INPUT LEVEL controller clockwise until you hear some distortion.
• Then turn back the INPUT LEVEL controller slightly until you can hear clean sound.
REFERENCE NOTE: If this controller is cranked up too high, the amplifier produce distortions, which may cause a
“creeping death” of the amplifier (or the speakers). Usually this is called “Clipping”.
BASS BOOST - controller
• Turn the BASS BOOST controller into “0dB” - position.
L R
REFERENCE NOTE: Ensure always correct polarity for all connections.
Don’t connect any speaker cables to the vehicle’s ground.
Wiring Diagram
REFERENCE NOTE: Never use the HI INPUTS and the RCA Inputs at the same time.

Green: Left Speaker +
Black: Ground
