Step 1. Connect the speaker cable from (+) terminal of the amplifier to (+) terminal of the speaker.

Step 2. Connect the speaker cable from (-) terminal of the amplifier to (-) terminal of the speaker.

Step 3. Repeat the installation sequence for each speaker step 1 and step 2

Caution!!! The minimum permissible connection load impedance at single channel is 2 ohm.

For ampliﬁers MLA-4080, MLA-4120 the operating voltage is 10-15 V.

Step 1. Connect one end of the RCA cable to the RCA output terminals at the HU and the second end to the amplifier

RCA inputs terminals marked with CH1/CH2, CH3/CH4.

HPF

1. CROSSOVER – HPF – high pass ﬁlter (10 Hz – 12 kHz at 12 dB/Oct)

2. CROSSOVER – selection of built-in ﬁlters operating mode (HPF, LPF / BP, FLAT)

3. CROSSOVER – LPF – low pass ﬁlter (10 Hz – 12 kHz at 12 dB/Oct)

4. BASS BOOST – bass level adjustment (0/6/12 dB)

5. GAIN – input signal level adjustment 0.2 V – 6 V

6. CH1/CH2, CH3/CH4 – signal input, RCA jacks

7. POWER – LED for operation (blue). PROTECT – LED for operation (red)

8. HI-LEVEL INPUT – high-level signal input (for model MLA-4080)
