Turning Power ON

 

There are two power switches on the Phono 1 phono stage – the AC mains switch at the 

rear left (looking at the rear of the Phono 1) and the top right button on the front dis-

play.  The rear switch needs to be ON before the top right button can be used to turn 

the unit ON or OFF.  The rear AC mains switch should be always ON except when 

equipment is stored.  

Before turning the Phono 1 on,

 connect the moving coil cartridge interconnects to 

the inputs of the phono stage and then connect the phono stage outputs to the pream-

plifier.   

Following this, you can then attach the power cord to connect the Phono 1 to the AC 

power mains.  This is an appropriate time to double-check all of your connections be-

fore the AC mains power is applied by turning the rear switch to on. 

Once your connections have been verified, you can now turn on the Phono 1 using the 

master power switch at the rear. Following this,  push the top right front display but-

ton.  The following picture is provided for identification of the rear AC mains power 

switch as well as the front ON/OFF (top right) button: 

Please Note:  Hazardous voltages inside the Tenor Phono 1 are dangerous!  Please al-

low 10 minutes for high voltage to dissipate before opening the Phono 1 chassis.  Never 

open the Phono 1 chassis with the rear switch turned on unless you are an experienced 

technician. 

The phono stage is designed to provide near full potential immediately following the 1 

minute  40  seconds  warm-up  and  stabilization  period.    Maximum  dynamic  headroom 

and transparency is achieved following about 60 minutes of continued operation when 

thermal equilibrium is achieved.
