TURN-ON LEAD

The M800/8-24V uses a conven12 to 

24V remote turn-on lead, typically controlled by 

the source unit’s remote turn-on output. The 

amplifier will turn on when any voltage between 

+12V and +24V is present at its Remote” input 

and turn off when this voltage is switched off. If a 

source unit does not have a dedicated remote 

turn-on output, the amplifier’s turn-on lead can 

be connected to +12V to +24V via a switch that 

derives power from an ignition-switched circuit.

NOT FOR USE IN 12V SYSTEMS!

The M800/8-24V’s “Remote” turn-on 

connector is designed to accept 18 AWG –  

12 AWG wire. To connect the remote turn-

on wire to the amplifier, first back out the set 

screw on the top of the terminal block, using 

the supplied 2.5mm hex wrench. Strip 1/2 inch 

(12mm) of wire and insert the bare wire into the 

terminal block, seating it firmly so that no bare 

wire is exposed. While holding the wire in the 

terminal, tighten the set screw firmly, taking 

care not to strip the head of the screw and 

making sure that the wire (not the insulation) is 

firmly gripped by the set screw.
