We understand that things infrequently go wrong, if you have any 

questions or problems please contact either your dealer or the factory, 

we are here to support the product and you, the user. 

 

As with all audio electronics the power cable should be the last thing 

attached and the first one removed any time you hook up or remove 

equipment from the signal chain. 

 

The preamplifier has five sets of stereo input connections, both single-

ended and balanced output connections and a full function remote 

control in addition to the normal complement of front panel control 

functions. 

 

The preamplifier's voltage and current rating are indicated by affixed 

tag on the rear of the preamplifier.  This tag will indicate 240 volts, 220 

volts, 120 volts, or 100 volts.  A 1.0 amp 3AG slow blow fuse is 

provided with 100-120 volt units, and a 0.5 amp slow blow fuse is 

provided with 220-240 volt units.  The input frequency rating of the 

power supply is 50 to 60 Hz.  The preamplifier typically draws 10 watts 

during operation.  Please verify that the indicated voltage requirement 

of this preamplifier is consistent with the utility voltage at your location. 

 

We have provided a standard IEC AC power cord that fits into the IEC 

320 line receptacle at the rear of the preamplifier chassis.  The 

preamplifier is equipped for operation with an earth ground provided by 

the users AC outlet.  Do not defeat this ground.  The chassis and 

circuit ground of the preamplifier are isolated from one another through 

a power thermistor, and bonded to earth through the chassis which 

gives a ground connection for safety but helps avoid ground loop 

related noise issues.
