Heed Warnings — All warnings on the appliance and in the
operating instructions should be adhered to.
Follow instructions — All operating and use instructions
should be followed.

The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and mainte-
nance (servicing) instructions in the literature
accompanying the appliance.
Heat — The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances (including arnplifiers) that produce heat.
Power Sources — The appliance should be connected to a
power supply only of the type described in the operating
instructions or as marked on the appliance.
Grounding or Polarization — The precautions that should
be taken so that the grounding or polarization means of
an appliance is not defeated.
Power Cord Protection — Power supply cords should be
routed so that they are not likely lo be walked on or
pinched by items placed upon or against them, paying
particular attention to cords at plugs, convenience recep-
tacles, and the point where they exit from the appliance.
Cleaning — The appliance should be cleaned only as
recommended by the manufacturer.
Nonuse Periods — The power cord of the appliance should
be unplugged from the outlet when lett unused for a long
period of time.
Object and Liquid Entry — Care should be taken so that
objects do not fall and liquids are not spilled into the enc-
losure through openings.
Damage Requiring Service — The appliance should be
serviced by qualified service personne! when:
A. The power supply cord or the plug has been damaged;
or
B. Objects have fallen, or liquid has been spilled into the
appliance; or
C. The appliance has been exposed to rain; or
D. The appliance does not appear to operate normally or
exhibits a marked change in performance; or
E. The appliance has been dropped, or the enclosure
damaged.
Servicing — The user should not attempt to service the

lions. All other servicing should be referred to qualified
service personnel.

Intorduction and Features
Thank you for purchasing the Model 5030 Line
Amplifier. Please read this information before using the
line amplifier in order to obtain the best performance.
The 5030 is designed to allow interfacing between
-4dBu balanced lines and -10dBV unbalanced lines. The
5030 has eight input and eight output line amplifiers.
In addition, there are two banks of switches on rear
panel. One bank is for adjusting the polarity of XLR
connector at the same time inputs and outputs. For best
results, please be sure that polarity is correct by using
these switches. The second bank of switches is for
changing the nominal level. These switches are only
effective between unbalanced inputs and outputs. With
these switches, you may choose between -6dBV or
-10dBV. Please set these switches according to your
needs.
Connections
Connecting the 5030 is a straight forward procedure.
There are only a few important points to remember.
First, make all connections while the power is off to the
5030. Second, make your connections according tothe
numbers on the back. Inother words, if you connect to
the number one XLR-3-31 input, connect the corre-
sponding RCA pin jack to the number 1 output. When
connecting an RCA pin jack to, for example, the number
7 input, be sure to connect the corresponding XLR-3-32
to the number 7 output.
XLR connectors
The connectors for the +4dBu signals are XLR-3-31
for the inputs and XLR-3-32 for the outputs.
