RACK-MOUNTING  REQUIREMENTS

The amplifier is designed to fit a standard 19” rack. While mounting, make sure to 

provide unhindered air access to the front and rear sides of the rack. Fan direction is from 
front to back. It is not necessary to leave empty space above or below the amplifier.

For stationary use, it will be enough to fix securely only the front panel of the amplifier 

to the rack. However, never attempt to transport the unit unless its rear end is properly 
supported and/or securely fixed, as it may be fraught with danger of damage.

AC  POWER  REQUIREMENTS

The  amplifier  is  supplied  with  a  three-conductor  grounded  AC  power  cord,  and 

should  be  plugged  into  a  standard  3-wire  grounded  electrical  outlet,  which  supplies 
230 VAC 50 / 60Hz.

In the event of line voltage sag, the amplifier without PFC will continue to operate 

normally, albeit with less power. The mains lower voltage limit for the amplifier to retain its 
operability is ~160 V.

The  amplifier  with  PFC  (

DF2008

DSP

)

  operates  at  the  mains  voltage  range  from 

~160 V to ~250 V, giving the full rated output power.

The amplifier is connected to the mains via cable, supplied with the amplifier. When 

connecting to mains, make sure that no other devices with high power consumption are 
connected to it, as the normal operation of several such devices may be impossible.

  The actual AC current consumption depends on the audio signal level and the load 

impedance. For system design purposes it must be noted, that for typical audio program 
material the amplifiers, driving all channels at nominal impedance, just peaking at the 
clipping level, have the following average power consumption:

– 2.2 A* for amplifier

  

DF1404

DSP

 at 4 Ohm load;

– 1.2 A* for amplifier

  

DF1404

DSP

 at 8 Ohm load;

– 

2.2 A*

 for amplifier 

DF1408

DSP

 at 8 Ohm load;

– 

3.2

A* for amplifier  

DF2008

DSP

 at 8 Ohm load;

– 

4.

5 A* for amplifier 

DF2804

DSP

 at 4 Ohm load

;

– 

2.

3 A* for amplifier 

DF2804

DSP

 at 8 Ohm load.

* At the mains voltage 230 V AC. For the amplifier with PFC (

DF2008

DSP

) in the low mains 

voltage, the current consumption increases.

In order to reduce the AC hum, please, plug all sound equipment, interconnected with 

signal cables, into the same power mains outlet.
