USE & PLACEMENT

 

 
The HEGEL HD25 should be placed on a flat, hard surface for proper isolation from vibrations.  
 
A certain space is required for air circulation above and below the D/A converter. The D/A converter 
must never be placed on a carpet or similar surface that obstructs air circulation through the unit. Nor 
must it be covered while in use or placed on a narrow shelf or in any other confined space. The D/A 
converter should not be placed on the top of an amplifier as the reduced airflow may cause damage to 
the D/A converter or the amplifier. 
 
The D/A converter performs best after being switched on for about 30 minutes to allow the 
temperature of the internal circuits to stabilize.  
 
The D/A converter will need “breaking in” for about 100 hours before maximum sound quality can be 
experienced.  
 
 

CLEANING

 

 
Fingerprints or stains on the front panel or top cover can be removed with a cloth moistened with 
warm water or a mild detergent suitable for cleaning mirrors and windows. 
 
 

TRANSPORT AND SHIPPING

 

 
If you are shipping the D/A Converter over a longer distance, please follow these instructions to 
prevent damaging it during transport: 
 
1.

 

First put a plastic bag around the D/A Converter 

 
2.

 

Fit the two shock absorbers on to the D/A Converter, one on the left side and one on the right side. 

 
3.

 

Then put it gently into the original cardboard box and secure it with adhesive tape to ensure that it 
does not open during shipment. 

 
 
We wish you good luck in setting up your new D/A Converter and hope that it will give you many 
years of joyful natural sounding music experiences!
