Connection to the amplifier 

Connect the 

Out

 of the phono amplifier to a line input (such as 

AUX

CD

Tuner

Tape

 or 

Video

) on your amplifier. 

Take care to connect the left and right channels correctly. The right channel is usually marked red, the left 
channel black or white. 

!

 

Make all connections whilst the phono amplifier is disconnected from the power supply. 
Do not connect the phono amplifiers output to a phono input (sometimes labelled 

gram

disc

 or 

RIAA

on the amplifier. 

Mains power connection 

The phono amplifier is supplied with a power supply suitable for your country's mains supply. Check the label 

before connecting to ensure compliance with the mains rating in your house. Connect the low voltage plug 
from the power supply to the 

Power ~16V

 socket of the phono amplifier before connecting the power supply to 

the mains. The blue LED on the unit's front will light up once the phono amplifier is properly connected to the 
power supply.
