Balanced Home Amp Rear Panel Panel

Rear Panel Descriptions

(see following page for DAC option descriptions)

1. Analog Inputs: 

 Two sets of RCA connectors allow for independent con-

nectivity of two separate non-digital (analog) sources like a CD player, tape 
deck or pre-amp into the Home amp.

2. Analog Input Selector:  

You may want to plug more than one analog 

source into your Home Amp.  Whether you are using one input or both, you 

will need to indicate which analog inputs you want to listen to by choosing 
either ‘1’ or ‘2’ with the analog input selector.

3. Balanced Inputs: 

The balanced input accepts a signal from a balanced 

output source (like from a quality CD player, for example) via stereo XLR con-

nectors.

4. Balanced Outputs: 

If you would like to use your Balanced Home as a 

pre-amp, these connectors provide fully balanced left/right outputs to your 

power  amplifier  or  powered  speakers  outfitted  with  balanced XLR-type  in-

puts. 

5. Rear Output: 

 

This set of RCA connectors is for pre-amp applications. 

You can send a signal either to powered speakers or directly to a power am-

plifier unit.

6. Ground Lift:

 Use this handy two-position switch to cancel out electrical 

hum interference coming from ungrounded or noisy outlets. For most appli-

cations, the switch should be set to “normal.” If you are hearing some buzz-

ing, try moving the ground lift to “float”.

7. Power Entry Module

:

 Plug in your AC power cord here. The “zero” po-

sition indicates off while the “one” means the unit is on and ready to go.  

The red window box on the power entry module indicates the current volt-

age setting of your amplifier.  You can easily switch the voltage between 115 

VAC and 230 VAC by carefully opening the power receptacle window housing, 

then simply slide out the receptacle and reinsert it facing the opposite way 

until the desired voltage clearly shows through the power module window 

box. The whole process should take less than a minute!
