TOSH

BALANCED LINE PREAMPLIFIER

REVISION P

R

A – JUNE 2023

8. Trigger Output

The 

TOSH

 can provide a trigger signal to another device. Typically, this is a power amplifier,

which is thus switched on and off by 

TOSH

 itself. To avoid disturbing speaker noises when 

switching on and off, the trigger output is activated after the 

TOSH

 has completed its switch-

on phase and is switched off before the preamplifier switch-off phase begins.
