5-Channel Amplifier - Speaker wiring and Connection
MXB 5900i
X-Over- (Front-/Rearsystem 1 up to 4 Channel)
• When you use bigger speaker systems (Ø20cm plus),set on FULL RANGE-position (FULL RANGE).
• When you use smaller speaker systems (Ø8.7cm - Ø16cm), set on HIGHPASS- position (HIPASS). The cut-off frequency should be
between 60Hz - 150Hz. It is controlled by the HIPASS-regulator.
Subwoofer (Channel 5)
• The cut-off frequency should be between 60Hz - 150Hz. It is controlled by the Lowpass-regulator.
Bass EQ-(Channel 5)
• Allows you to adjust the bass boost from 0dB up to 12dB.
Caution! Please use the Bass-Boost carefully. The additional boost may result in clipping or overload.
Subsonic-filter (Channel 5)
• Eliminates the lowest frequencies to protect your Subwoofer from damages. Cut-off frequency should be between
20Hz and 55Hz
Level
• Turn the INPUT LEVEL control on the amplifier to 5V position.
• Turn the head unit volume control to about 80-90% of its full setting.
• Turn the INPUT LEVEL control clockwise until you hear some distortion.
• Then turn back the INPUT LEVEL control slightly until you can hear clean sound.
Mode
• Set mode switch on 5CH-position

Interconect Cable checklist :
• Connect the RCA outputs from head unit with the RCA Inputs (LINE INPUT 1CH&2CH / 3CH&4CH) of
the 4 Channel amplifier with two RCA Cables.
• Connect the RCA outputs of the (LINE OUT) 4-Channel Amplifier with the RCA inputs(LINE INPUT) of
the 1-Channel/Mono amplifier with an RCA cable.
• Connect the Front- & Rear-Speakers with a good RCA cable with the speaker outputs (SPEAKER
OUTPUT/ + 1CH -, + 2CH -, + 3CH -, + 4CH -) of the 4-Channel amplifier.
• Connect the Subwoofer with a good RCA Cable with the Speaker outputs (SPEAKER / + -) of the 1-
Channel/Mono Amplifier.
• The minimum final speaker impedance must not be below 2 Ohm per channel. Too low speaker loads
result in too high heat dissipation and may cause the amplifier run into protection.
• Please observe speaker channel and polarity as printed by the speaker terminal
