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 

Zero1

 amplifiers.

Minimum impedance is 2   .

Output signal can be routed from 1 master amplifier 

to 2 slave amplifiers, by setting the switch to SLAVE1

& SLAVE2 on the amplifiers in question. 

DO NOT USE IN DAISY CHAIN MODE!

 

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.

BASS FREQ

Variable bass boost frequency from 30Hz ~ 80Hz 

                                                     

SPEAKER OUTPUTS

                                                     

Amplifier connection to the loudspeakers.

 

                                                     

Minimum speaker cable is 12 gauge.

                                                     

Minimum impedance for the 

Zero1 

is 1   if

                                                     

used as a single unit.

                                                     

In a daisy chain configuration the minimum

 

 

 

        impedance is 2   .
