INPUT

Signal input from the head unit. A minimum level 

input of 0.2V is essential for correct operation.

POWER & PROTECTION INDICATOR

Power LED, Blue-lit shows correct operation. 

Protect LED, Red-lit shows general malfunction, 

faulty connection or thermal protection. 

GAIN (6V ~ 0.2V)

Matching of the output voltage from the head unit’s

RCA line-outs to the input section. 

SUBSONIC FILTER (10Hz ~ 50Hz @ 24dB/Oct)

Adjusts the subsonic cut off point to eliminate

frequencies within the filter’s range. 

 

REMOTE LEVEL CONTROL PORT

Connection of external level control. 

(The 

Better Bass Remote

 

can be connected for additional features).

OUTPUT MASTER / INPUT SLAVE

For daisy chain connection of 2 

M1u

 

 amplifiers.

Minimum impedance is 2   .

 

LOW PASS FILTER (35Hz ~ 250Hz @ 24dB/Oct)

Adjusts the cut off point for the low pass filter

within the filter’s range.

PHASE CONTROL

Variable phase adjustment from 0-180 degrees.

BASS BOOST

Variable bass boost with 0-9dB @ 45Hz. 

                                                     

SPEAKER OUTPUTS

                                                     

Amplifier connection to the loudspeakers.

 

                                                     

Minimum speaker cable is 12 gauge.

                                                     

Minimum impedance for the 

M1u 

is 1    if
