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

 

Zero.7

 

amplifiers.

Minimum impedance is 2

   .

Output signal can be routed from 1 master amplifier 

to 1 slave amplifier by setting the switch to INPUT SLAVE

on the slave amplifier and use the RCA IN / OUT

on the designated unit. This will invert the phase on the  

slave amplifier and allow both amplifiers to work as 1 unit.

 

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.

Panel layout

BASS BOOST

Variable bass boost with 0-9dB at 45 Hz

                                                     

SPEAKER OUTPUTS

                                                     

Amplifier connection to the loudspeakers. 

                                                     

Minimum speaker cable is 12 gauge.

                                                     

Minimum impedance for the

 

Zero.7 

is 1   if

                                                     

used as a single unit.

                                                     

In a daisy chain configuration the minimum

 

 

 

        impedance is 2

  

 .
