Logitek Standard Elec. Cable Manufacturing MON-10 - Manual (Page 5)

SECTION 2 — PREPARATION FOR USE
2-1 Initial Inspection
Check the shipping carton carefully for external
damage. If the carton shows evidence of abuse, ask
the carrier’s agent to be present when the unit is un-
packed. Carefully unpack the unit to avoid damaging
the equipment through the use of careless proce-
dures. Inspect all equipment for damages immediately
after unpacking. Bent and broken parts, dents, and
scratches should be noted. If damage is found, refer to
paragraph 2-2 for recommended claim procedures.
Keep all packing material for possible future use.
2-2 Claims
If the unit has been damaged, notify the carrier im-
mediately. File a claim with the carrier and advise
Logitek of such action to arrange for repair or replace-
ment without waiting for a claim to be settled with the
carrier.
2-3 Repacking for Shipment
If the unit must be returned to Logitek, attach a let-
ter to it showing the owner’s name and address. A de-
scription of necessary service should be included in
the letter. The original shipping carton and packaging
materials should be used for reshipment if possible.
Use FRAGILE labels on each surface. Return the unit
freight prepaid. Be sure to insure the unit for its full
value. The unit will be repaired promptly and returned
freight prepaid.
2-4 Installation
The MON-10 is designed to be mounted in a stan-
dard 19" equipment rack by using the four mounting
holes in the corners of the front panel. While
flow-through ventilation is not necessary, the unit
should not be mounted directly above equipment
which produces significant heat, such as equipment
using vacuum tubes. The unit should never be oper-
ated if the ambient temperature is above 55 degrees C
(131 degrees F).
2-5 Connecting Inputs and Outputs
All inputs and outputs (except the headphone out-
put) are connected via the barrier strips on the rear
panel. These terminals are “wire-capturing”, so it is
not necessary to attach crimp lugs to each wire before
fastening the wire to the terminal. Crimp lugs may be
used, however, if desired.
Balanced line-level inputs and the line output
should be connected the to terminals as indicated on
the rear panel. Unbalanced sources can be fed to the
MON-10 by connecting the “hot” lead from the unbal-
anced source to the “+” input terminal on the MON-10,
while connecting the “-” terminal on the MON-10 to the
accompanying MON-10 ground terminal.
Unbalanced equipment can be fed from the output
of the MON-10 by connecting the “+” terminal on the
MON-10 to the “hot” input on the unbalanced equip-
ment, while leaving the “-” terminal on the MON-10 un-
connected. Connect the cable shield to the ground
side of the input connector on the unbalanced unit.
When feeding unbalanced equipment from the output
of the MON-10, it is important that the “-” output termi-
nal be left unconnected. Connecting this terminal to
ground will not harm the equipment. However, it might
cause undesired crosstalk.
Care should be taken to be sure that cable shields
are connected to grounded equipment on only one
end of the cable. On any cable which connects two
pieces of equipment, of which both are grounded, the
cable shield must be left unconnected on one end, or
poor noise performance may result.
An external speaker may be connected to the
SPEAKER OUT terminals on the rear panel. For best
performance, be sure that the speaker ground return
is connected to the indicated ground terminals on the
unit. To use the speaker on the front panel, connect
the SPEAKER OUT terminal to the INTERNAL
SPEAKER terminal. DO NOT CONNECT BOTH AN
EXTERNAL SPEAKER AND THE INTERNAL
SPEAKER AT THE SAME TIME, AS THE AM-
PLIFIER MAY BE DAMAGED IF YOU DO.
