Tips and Hints 

AMP3300R

’s revolutionary 

LEF

-amplifier circuit is providing the highest available sound quality by 

combining “Single Ended Class-A” operation, high power and no negative feedback in the signal 
path. The transistor faults are neutralized.

 Never connect any speaker terminal to ground. Due to the full balanced design of 

AMP3300R

 both 

speaker terminals are active. Watch out when connecting active subwoofers or similar devices to 
the speaker terminals. A short circuit to ground might damage the 

AMP3300R

 or at least break a 

fuse.

 The speaker terminal DC voltage is not 0 to ground - this is not an amplifier fault.

 The maximum power is not specifically on 100% volume. Depending on the source voltage the 

maximum power might be between 60% and 100% volume.

 Minimum volume is not absolute silence, due to 

AMP3300R

‘s special gain management. 

U

Use“Mute“ for silence. 

Special Protecting Functions 

In addition to usual fuses and protection circuits, 

AMP3300R

 offers two special functions to protect 

your HiFi-Investment: 

1.: Even if 

AMP3300R 

sounds like unlimited power, it is not unlimited and therefore is protected from 

continuous clipping. Clipping means exceeding the maximum output voltage. 

AMP3300R

 automati-

cally reduces the volume by turning back the volume knob until no clipping occurs. 

2.: In case of overheating due to insufficient ventilation, high external temperature and/or high listening 
levels 

AMP3300R

 completely shuts down by a heat detecting switch. Depending on ventilation 

AMP3300R

 switches on again after 5 - 10 minutes. 

Maintaining Your AMP3300R 

x

AMP3300R

 requires no periodic maintenance and has no user serviceable parts inside. 

x

To keep it clean only  use a soft cloth and never use any solvents or abrasives. Dust and 
fingerprints may be removed with a soft cloth moistened only with a few drops of water.

x

The power cord should be removed whenever the unit will be unused for an extended period.

Supplied Accessories

The delivery includes a remote controller and a power cord.

Repacking

• Do not throw away the carton box and the packing material.
