High End Integrated Amplifier ASR Emitter I and II  version 2009 on    Page 3

 

 

2. 

The Emitters are equipped with AC power cords which three plugs that include an 

earth 

ground connection

. To prevent shock hazard, the earth ground connection should be used.  

If your electrical outlets has no separate ground connection please use other ones that have  
a earth ground connection. If you are not sure of the integrity of your home’s electrical system, 
contact a licensed electrician for assistance.

 

3. 

AC extension

 cords are 

not recommended

 for use with this product. If an extension cord  

must be used, be sure it is an approved type and has sufficient current carrying capacity  
to power this product.

 

4.

 

Before cleaning the ASR Emitter, always turn Off the unit and unplug the power supply 

cords. 

5.

 

If you smell smoke, or an abnormal smell, immediately turn Off the ASR Emitter and 

unplug the unit from the power supply and contact your ASR dealer. 

6. 

Don’t expose the Emitter to water or any liquid. Unplug immediately if the unit becomes 

wet.

 

7.

 

Replace fuse only with the exact type originally included.

THERE ARE NO SERVICEABLE PARTS INSIDE THE ASR EMITTER ! 

-

 

Do not attempt to repair or modify your ASR Emitter. 

-

 

All service should be performed by qualified service personnel. 

-

 

Do not open the units while it is attached to the AC outlet. 

 

1.3

 

Placing the Emitter units 

The 

heat sinks

 of the ASR Emitter 

radiate

 some heat, so please place the main unit in a place, 

where 

air

 can 

circulate

 around the heat sinks. Never put another unit on top of the main unit.

 

The ASR power supplies do not radiate much heat. For best sonic performance please do not stack 
the ASR power supplies units nor place the ASR power supply units too close to the main unit.

Connecting the ASR Emitter to your system 

 
All 

standard inputs

 of the ASR Emitter are high level inputs with 

identical technical 

characteristics

, just the name is different. For connection of a turntables you may use the

 

ASR plug-in phono board or a separate phono preamplifier.

 

 

 

The source components should be placed close to the ASR Emitter’s main unit.

 

 

To obtain the best performance please use cables as short as possible.

 

 

If your source components are equipped with „fixed“ and „variable“ outputs always use 

        the „fixed“ outputs to connect the component to the ASR Emitter for better performance.

 

 

ATTENTION:  

When you plug cables to the main unit please switch OFF the Emitter !

 

If you want to be absolutely save unplug the power cords to the AC outlet !

 

 

Tipp:

 please use high quality interconnects, speaker cables and power cords to connect your ASR 

Emitter. The performance of your system will be increased by using the best affordable cables.
