OPERATION 

 

 

7

Operating this component is a simple procedure. Each unit is designed for long term stability in 

virtually any home operating situation. However, if the unit is operated outside the parameters 

outlined in this owner's manual, damage may result. Please read this manual carefully before 
putting your new unit into operation. 

 

CONNECTIONS 

 

Balanced Inputs:  

Accepts right-channel and left-channel balanced signals from a 

source component with balanced outputs. 

 

Single-ended Inputs:  

Accepts right-channel and left-channel (single-ended) inputs from a 

source component. 

 

Balanced Main Outputs:  

These are for connection to the XLR input jacks of an accompanying 

power amplifier or electronic crossover. 

 

Single-ended Outputs:  

These are for connection to the RCA input jacks of an accompanying 

power amplifier or electronic crossover. 

 

 

CHECKING CONNECTIONS 
 

1.

 

Make sure that all the connections are proper by referring to the rear panel labels. 

2.

 

Check the directivity of stereo separation (right channel to right channel, left channel to left 

channel). 

3.

 

Check the directivity of pin cord connection, if your patch cables are labeled for direction of 
connection. 

 

 

SWITCHING ON 

 

POWER button 

 

Press once to turn the power “ON”. 

 

Press again to set to the "OFF" position and turn the power off. The amplifier will enter 
into Standby and the blue LED will light. 

 

SOURCE SELECT buttons

 

 

Press once to select the desired input source. 

 

VOLUME knob

 

 

Turn the volume knob to the desired listening level. 

 

BREAKING-IN 

 

 

The CPA 1 requires at least 100 hours of continuous operation after it is first turned on 
to sound its best. This gives the materials in various circuit components a chance to 

"form" so audio signals achieve greater definition, smoothness and transparency. 

Although the unit will sound spectacular when you first operate it, you will find it 

worthwhile to listen again after a few days and you'll discover details in your music you 

may not have noticed were there.
