The JRDG CAPRI Stereo 
Preamplifier has been designed 
to operate at the highest level of 
efficiency and performance in 
any normal operating situation; 
however, there are a few important 
use and care principles that must  
be kept in mind when operating 
the preamplifier:

• Do not expose the preamplifier  

to rain, moisture, or excessively 
damp conditions.

• Due to auto-ranging circuitry and 

dual-stage voltage regulation, the 
audio performance will not be  
affected by any voltage fluctuations 
within the operating voltage range. 
The CAPRI Stereo Preamplifier can 
be operated at any mains voltage 
over the range of 85 to 265 VAC 
without any adjustments necessary. 

• The CAPRI Stereo Preamplifier must  

not be modified in any way, other 
than according to official service 
bulletins from JRDG. Otherwise, the 
factory warranty will be immediately 
voided.

• Be sure the preamplifier is muted  

(red front panel indicator light on) 
before connecting or disconnecting 
any interconnect cables.

• When operating the CAPRI, a  

properly grounded AC receptacle 
should be used. A potential shock 
hazard may result if the supplied  
3-wire, grounded AC cable ground  
terminal is defeated or lifted or 
the unit is connected to a 2-wire 
ungrounded AC outlet.

• The CAPRI is designed to perform 

optimally with no adjustments or 
maintenance for the lifetime of the 
product. Do not attempt to open the 
bottom cover of the preamplifier and 
refer all service issues to qualified 
personnel. The voltages inside the 
CAPRI can be hazardous.

• Because of the energy efficiency  

of the CAPRI, there is no need to 
unplug the unit when not in use;  
however, the preamplifier can be 
muted if desired.
