INSTALLATION
Always connect the main power with 3-prong plug Make sure the power system ground is properly done Don, t use ground
insulator plug adapter without properly connect the ground individually This is vital to a successful audio system
connection
Always connect the ground pin(PIN I in 1/ 4
,,
TRS)to the source unit, and disconnect this pin at the destination unit This
connection topology is to avoid grounding loop created by both connection of signal and power ground To utilize only the
power ground, is because it always has lower resistance and better distribution than signal ground
If there is hum a very possible cause is bad grounding connection in the system In case you can not find the cause , try to
connect the ground pin of the input connectors if the hum is reduced or eliminated, check your power grounding system
Special attention while distant equipment racks, and/or large quantity of power amplifiers are used Check the power
ground between the racks and power distribution strips with your electricity engineer Do make sure there is one and only
one proper ground point in the audio system(or connected video System)

The Correct Wiring for Balanced Operation
this Installation is equipped with electrionically balanced inputs and outputs which also function unbalanced inputs and
outputs The cross-feedback circuitry recognizes the connection of unbalanced loads and compensates 6 dB level difference
when one of the sig nal is shorted to the ground For connecting with unbalanced source to the input of Installation connect PIN
2 Of 1 /4
,,
TRS connector to the Source signal and the PIN 1 and 3 of 1/ 4
,,
TRS connector of Installation to the Source around
For connected with unbalanced load to Installation there are 2 possible wiring methods
(1)Connect PIN 2 of 1/ 4
,,
TRS connector to the load input, and connect PIN 1 OF 1/ 4,, TRS connector to the load ground
(2)Connect PIN 2 of 1/ 4
,,
TRS connector to the load input, and connect PIN 1 and 3 of 1/ 4,,TRS connector to the load
Ground
Unbalanced Operation
The electrically balanced connections have the ben efit of Common Mode Rejection which eliminates externally induced
inte rference such as mains hum etc Balancing is especially useful when long calbe runs are used between pieces of
equipment
For connecting with balanced source to the input of Installation, connect PIN 2 of 1/ 4,,TRS connector to the source signal
Hot(+), the PIN 3 to the source signal Cold(-)and the PIN 1 to the source Ground
Balanced Operation
The mains connection of the Installation is made by using a standard IEC receptacle and an universal mains cable lt meets all
the requirements of the international safety certification
Make sure all the units in the sound system are properly grounded with good connection For your own safety, do not to
remove the ground connection within the units Or at the supply or fall to make this connection at all
The audio around of the Installation is capacitor de-Coupled and isolate it from the power around Do not attempt to solve ground
loop problem by disco nnecting the power ground
MANS CONNECTON
A safety fuse protects the unit from serious malfunction The fuse wblows in case of power problem Or loading short circuits
After removing the cause and the identical spe cification fuse blows right after a new one replaced there must be something
wrong in the unit
NEVER use fuses higher or loer ratings fuses or other metal material This can cause fire and electric shocks and
wheaten you life and the lies of others
