INSTALLATION NOTES
2
Since the generates
modest amounts of heat, adequate
ventilation is required. Do not place the
amplifier on a soft surface such as a
carpeted surface that may block the
ventilation holes of the bottom cover. Also,
avoid obstructing the ventilation holes in the
top cover.
To prevent the risk of fire or
shock, do not allow any liquid or moisture to
enter into the internal parts of this product. If
any liquid accidentally enters this product,
shut off the power and remove the AC power
cord immediately. If the liquid is anything
other than clean water or pure alcohol, have
the product examined by a service
technician. Servicing of this product should
be referred to a qualified service technician.
Your amplifier is set to work on your
local mains supply voltage. Check that your
local mains supply voltage agrees with the
voltage setting indicated on the back panel of
the amplifier. If not, please contact your
dealer or national distributor for details on
how to proceed further.
The cores of the mains lead are coloured in
accordance with the following code:
Blue -Neutral
Brown -Live
Note: Export units for certain markets have
moulded mains plugs fitted as standard.
As the colours in the mains lead may not
correspond with the coloured markings
identifying the terminals in your plug,
proceed as follows:
The wire which is coloured blue must be
connected to the terminal which is marked by
the letter N, or coloured black or blue. The
wire which is coloured brown must be
connected to the terminal which is marked by
the letter L, or coloured red or brown.

Connect the AC line cord in to the mains inlet
and plug the AC cord plug into a nearby wall
outlet that provides the correct AC power line
voltage.
Each channel of the 2N100MKII has its own,
independent level control. Before turning on
the 2N100MKII for the first time, make sure
that all level controls are set to their fully
clockwise position. These controls can be
used for various functions. For example, they
can be used to match the levels of
loudspeakers in a multi-room installation, or
to lower the sensitivity of the power amplifier,
so that the volume control on pre-amplifier is
at a more convenient and usable position.
They can also be used to optimise the
balance in a stereo system.
Each input has an accompanying line output
which will pass the signal onto another
amplifier input or other line-level device.
There are two (or three) RCA phono
connectors on the back panel that connect to
the inputs of each of the power amplifiers.
The 2N100MKII is equipped with binding
post type speaker terminals that are
designed to handle the extremely high peak
currents that this amplifier is capable of
giving. Connections from these terminals to
the loudspeakers should be made with
heavy-duty wire. Standard wire of 16 gauge
or thicker is recommended especially if low
impedance loudspeakers are used.
UNDER NO CIRCUMSTANCES SHOULD
THE OUTPUTS BE SHORTED TOGETHER.
There is one unswitched convenience AC
outlet on the back panel of the 2N100MKII.
The outlet can be used to provide AC power
for other audio or video components.
The press button switch marked power can
be used to switch the 2N100MKII on or off.
When the 2N100MKII is switched on, the
small indicator above the power switch will
glow green.
UNDER NO CIRCUMSTANCES SHOULD
THE CASE OF THE AMPLIFIER BE
OPENED BY ANYONE OTHER THAN A
QUALIFIED ENGINEER, AS DANGEROUS
VOLTAGES ARE PRESENT INSIDE. ANY
UNAUTHORIZED REPAIR MAY
INVALIDATE YOUR WARRANTY.

Weltronics Corp. reserved the right to improve its products at any time. Specifications are
subject to change without notice.

All the safety and operating instructions should be read
before the appliance is operated.
The safety and operating instructions should be retained for
future reference.
All warnings on the appliance and in the operating instructions
should be adhered to.
All operating and use instructions should be followed.
The appliance should not be used near water - for example,
near a bathtub, washbowl, kitchen sink, laundry tub, in a wet
basement, or near a swimming pool, etc.
The appliance should be used only with a cart or stand that is
recommended by the manufacturer.
An appliance and cart combination should be
moved with care. Quick stops, excessive force,
and uneven surfaces may cause the appliance
and cart combination to overturn.
This equipment is not designed for use mounted on a wall or a

The appliance should be situated so that its location or position
does not interfere with its proper ventilation. For example, the
appliance should not be situated on a bed, sofa, rug, or similar
surface that may block the ventilation openings, or placed in a
built-in installation, such as bookcase or cabinet that may
impede the flow of air through the ventilation openings.
The appliance should be situated away from heat sources
such as radiators, heat registers, stoves, or other appliances
(including amplifiers) that produce heat.
The appliance should be connected to a power supply only of
the type described in the operating instructions or as marked
on the appliance.
Power-supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against
them, paying particular attention to cords at plugs,
convenience receptacles, and the point where they exit from
the appliance
The appliance should be cleaned only as recommended by
the manufacturer.
The power cord of the appliance should be unplugged from the
outlet when left unused for a long period of time.
Care should be taken so that objects do not fall and liquids are
not spilled into the enclosure through openings.
The user should not attempt to service the appliance beyond
that described in the operating instructions. All other servicing
should be referred to qualified service personnel.
The appliance should be serviced by qualified service
personnel when:
a) The power-supply cord or the plug has been damaged; or

(APPLIES TO TUNERAND RECEIVERS ONLY)
An outdoor antenna should be located away from power lines.
(APPLIES TO TUNERAND RECEIVERS ONLY)
If an outside antenna is connected to the receiver, be sure the
antenna system is grounded so as to provide some protection
against voltage surges and built up static charges.
Section 810 of the National Electrical Code,ANSI/NFPA No.
70-1984, provides information with respect to proper
grounding of the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, size of grounding
conductors, location of antenna-discharge unit, connection to
grounding electrodes, and requirements for the grounding
electrode. See Figure.
a) Use No. 10 AWG (5.3 mm ) copper, No. 8 AWG (8.4 mm )
aluminum, No. 17 AWG (1.0 mm ) copper-clad steel or
bronze wire, or larger, as a ground wire.
b) Secure antenna lead-in and ground wires to house with
stand-off insulators spaced from 4-6 feet (1.22-1.83 m)
apart.
c) Mount antenna discharge unit as close as possible to where
lead-in enters house.
d) Use jumper wire not smaller than No.6 AWG (13.3 mm )
copper, or the equivalent, when a separate antenna-
grounding electrode is used. See NEC Section 810-21(j).
