GETTING STARTED
Check the AC voltage before connecting the plug The unit must be properly g rounded to avoid electrical shock to the
operator. Choose the main supply for the sound system with care, and do not share sockets or g rounding with light
dimmers.
Separate audio cables from dimmer wiring using balanced lines wherever possible lf feasible, cross a udio and lighting
cables at right angles to minimize the possibility of interference Keep unbalanced cables as short as possible.
Check your cables regularly and label each end for easy identification.
Before switching on the main power, set the input level control to its minimum setting Doing so will prevent excessive
noise caused by bad level adjustment, faulty wiring, defective cables, or bad connections.
Always turn the unit on before turning on the power amplifier; always turn it off after turning off the amplifier.
Always turn off the main power before connecting or disconnecting the unit.
Never use solvents to clean the unit Clean the unit with a soft, dry cloth.

INSTALLATION
The Phonic Installation fits into standard rack, and takes one unit height of space(1 3/ 4,, )Additional 4,, depth for the con-
nectors on the back panel is needed Be sure that there is enough air space around the unit for cooling and please do not
place the Installation in contact to or directly on top of high tem perature devices such as power amplifiers etc to avoid
overheating
RACK MOUNTNG
The Installation has to be connected with 1/4,, TRS plugs Although the inputs and outputs are fully balanced, the active
servo circ uitry can be wired with unbalanced soureces and loads as well
CONNECTORS
Both of the inputs impedance are 20k Ohms and can be driven by most sources lf a device,s output requires a match load of
600 Ohms(mostly from output transformers), 600 Ohms resistor should be tied across pin 2 and 3 on the input connectors
As standard the outputs of the Installation are electronically bala nced and have an output impedance lower than 100 ohms
When driving transformer coupled loads it may be ne cessary to create a 600 Ohm source impedance For this purpose install
two 247 0hms resistors in series with Pin 2 and 3
Impedance
Most of the mistakes in audio installations are incorrect and defective audio connections In order to perfectly complete your
installation, please pay special attention to the following section unless you are already familiar with balanced/unbalanced
operation
Unbalanced/Balanced Connection
You can find this system in most of home audio-video system It got one conductor to carry the signal, and the other
conductor for ground Normally for lower level signal, the signal conductor is shielded by the ground Conductor
What is an unbalanced system?
Balanced system transmits the signal via 2 conductors plus one ground shielding conductor The 2 signal conductors carry
the same signal but out of phase For the balanced input stage, the amplifier will boost the difference of the 2 signal
conductors and remove the identical pa rt (known as common mode signal) of the 2 signal conductors Because of the real
signal is carried by the 2 conductors out of phase, so it is perfectly carry to the input At the same time, the inte rference
occurs during transmission will be identical part(common mode), beca use the signal conductors are run together, there is
no chance they can be different, and all the interfere nce will be removed by the bala nced input amplifier
What is a balabced ststen?
Because the common mode interference immunity of balanced system, and at the same time, the ground conductor
doe sn,t need to carry any electrical current so that it means the ground of the 2 connected units has identical ground level
which is vital to interference free system
Let, s look back to unbalanced system, the signal electrical current is from signal conductor to ground conductor, and that
means the ground level of 2 connected units are not identical This means the system is much more easier to be interfered
with noise
Running long cables is easy for bala nced system but difficult for unbalanced system, and lower noise is always
characterized in balanced system
B ecause balanced system needs 2 cond uctors for signal and 1 conductor for ground minimum 3 conductors are needed for
wiring balanced system So dedicated system separates ground and shield as 2 conductors
Please read following section for proper wiring balanced and unbalanced system:
The difference in between 2 operations:
Normal-phase signal
+ normal-phase noise.
Desired signal
with no noise.
Normal-phase signal
+ reverse-phase noise.
Unbalanced lines are fine if you,re in
a relatively noise-free environment.
The ambient electromagnetic noise
level will be the ultimate deciding
factor, but balanced is best.

CONNEC TIONS
With balanced XLR and TRS 1/ 4,, nput lacks you could use either XLR or TRS L ine input Jack for connection These input
Jacks a ccept balan ced as well as unbalanced input When sending unbalanced signal, the Ring and the Sleeve of the TRS
Jack must be conceded, the 3rd pin and the 1 st pin of the XLR connector should be connected as well, or simply use a TS
phone jack for making the connection.
4
The name phone jack arose simply because this configuration was first used in telephone switchboards. Phone jacks
can be tricky because you can ,t always tell what type of signal they ,re designed to handle just by looking at them, It
could be unbalanced mono, unbalanced stereo, balanced mono, or an insert patch point. The connector ,slabel
will usually tell you what type of signal it handles, as will the owner,smanual (you do keep your manuals in a safe place,
Don, tyou?). Aphone jack that is set up to handle balanced signals is also ofter referred to asa TRS phone jack.
TRS stands for Tip-Ring-Sleeve, which describes the configuration of the phone plug used.

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
2Of1/4
,,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
