10 Power Sources — The appliance should be
connected to a power supply only of the type
described in the operating instructions or as marke
on the appliance.
11 Power-Cord Protection — 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 a
plugs, convenience receptacles, and the point whei
they exit from the appliance.
12 Cleaning — The appliance should be cleaned c
as recommended by the manufacturer.
13 Nonuse Periods — The power cord of the
appliance should be unplugged from the outlet whi
left unused for a long period of time.
14 Object and Liquid Entry — Care should be take
so that objects do not fall into and liquids are not
spilled into the inside of the appliance.
15 Damage Requiring Service — The appliance should
be serviced by qualified service personnel 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 normaily
or exhibits a marked change in. performance; or
E. The appliance has been dropped, or the cabinet
damaged.
16 Servicing — The user should not attempt to service
the appliance beyond those means described in the
operating instructions. All. other servicing should be
referred to qualified service personnel.
17 Power Lines — An outdoor antenna should be
located away from power lines.
18 Grounding or Polarization — The precautions that
should be taken so that the grounding or polarization
is not defeated. |
19 Speaker Connection — To reduce the risk of shock
or fire and prevent short circuits, strictly follow the
instructions for connecting speakers on p. 8.
CAUTION: READ THIS BEFORE OPERATING YOUR UNIT
1 To ensure the finest performance, please read this
manual carefully. Keep it in a safe place for future
reference.
2 Install your unit in a cool, dry, clean place — away
from windows, heat sources, and too much vibration,
dust, moisture or cold. Avoid sources of hum
(transformers, motors). To prevent fire or electrical
shock, do not expose to rain and water.
3 Do not operate the amplifier upside-down. It may
overheat, possibly causing damage. |
4 Never open the cabinet. If a foreign object drops
into the set, contact your dealer.
5 Do not place records or other objects on top of
the amplifier; this will block the ventilation holes, cause
the internal temperature to rise and may result in a
failure.
6 Do not use force on switches, knobs or cords.
When moving the set, first turn the unit off. Then
gently disconnect the power plug and the cords
connecting to other equipment. Never pull the cord
itself. |
7 Do not attempt to clean the unit with chemical
solvents; this might damage the finish. Use a clean,
dry cloth.
8 Be sure to read the “Troubleshooting” section on
common operating errors before concluding that your
unit is faulty.
9 Do not connect audio equipment to the AC
outlets on the rear panel if that equipment requires
more power than the outlets are rated to provide.

4 POWER switch/indicator (POWER)
Press this switch to switch ON the power. The indicator above it will
lluminate while the power is ON.
Press the switch again to switch OFF the power. Note the following
cautions.
e Before switching ON the power, be sure to set the volume control(s) of
the control amplifier to the lowest setting in order to avoid damage to
the speakers.
® The speaker-protection circuit functions to mute speaker sound
reproduction for a few seconds after the power is switched ON.
@ SPEAKERS switches (SPEAKERS)
MX-830
These switches permit you to select any of the speaker pairs connected
to the A, B and/or C terminals by pressing the appropriate switch(es) to
the ON position.
Note: If speakers are connected to terminals B, but not to terminals C,
be sure to press only the switch B when listening via pair B. Pressing
switch C as well will cut off the sound from pair B, because B and C
are connected in series. (The same is true if speakers are connected to
terminals C and switch B is pressed.)

These switches permit you to select any of the speaker pairs connected
to the A and/or B terminals by pressing the appropriate switch(es) to the
ON position.
O CLIPPING indicators (CLIPPING)
These indicators illuminate if an overload is applied to this unit due to
excessive input. (When this indicator illuminates, reduce the input level by
using the output level control on the control amplifier or other component
connected to this unit.) |
(9 Speakers level controls (LEVEL)
These controls are used for adjustment of the volume level of the sound
reproduced through the speaker systems connected to this unit. Tuming a
control clockwise increases the volume level from the speaker system(s)
corresponding to that control.
REAR PANEL
O INPUT terminals (INPUT)
These terminals are for connections from a control amplifier.
Refer to the section “CONNECTIONS” for detailed information.
O Ground terminal knob (GND)
Make a connection beiween this terminal and the same terminal of the
control amplifier if making the connection results in less hum or other
noise.
@ Speakers terminals
These terminals are for connections to the speaker systems.
Refer to the section “CONNECTIONS” for detailed information.
© Unswitched AC outlet (AC OUTLET UNSWITCHED)
(U.S.A, Canada and General models only)
This unswitched AC outlet can be used for connection of the power col
from another audio component. Note that the power to that component
not affected by the ON or OFF setting of the POWER switch of this un
Note: The component connected here should have a rating of no more
than 200W.
(See Fig. JA
After confirming that the control amplifier is also switched off, connect the
output jacks of the control amplifier to the corresponding INPUT jacks on
the rear panel of this unit. Always check to be sure that:
the RCA plugs of the connecting cord are clean,
the left and right channels of both units correspond,
connections are secure, and
both units are properly grounded.
SPEAKER CONNECTIONS
MX-830
This unit can drive up to three pairs of speakers (A, B and C) at the
same time. Those connected to terminals À are in parallel with pairs B
and C, which are in series. The following table shows the minimum load
impedances per speaker for all possible connections.
Number of MX-830 Minimum speaker
speakers terminals load impedance
(per speaker)
1 pair | Ао Во С 4 ohms
2 pairs in parallel А + Во А + С 8 ohms
2 pairs in series B+ C 2 ohms
3 pairs A+B + С A: 8 oms
B, C: 4 ohms
Be sure to use only speakers within the rated impedance range and with
adequate power handling capacity. Driving speakers with extremely low
impedance (or several low-impedance pairs simultaneously) at continuous
full power may cause the protection circuit of this unit to activate.
When connecting the speaker cords, observe the “+” and “—" markings
on the backs of the speakers and this unit. If the “+” and “—" polarities
are reversed, the sound will be unnatural and lack bass.
Speaker cords should be cut as short as possible. Do not roll up excess
cord or bundle it with cables from other components.
Strip approximately 10 mm (3/8”) insulation from the ends of the speaker
cords and connect them as explained below:
Light-gauge speaker cords
Partly unscrew the plastic wire holders. Insert the stripped ends of the
speaker cords as shown, and retighten the holders.
Red: positive (+)
Black: negative (-)
Heavy-gauge speaker cords
First, unscrew and remove the plastic wire holders. Insert the stripped
ends of the speaker cords into the holders until they protrude from the
other side.
Splay the strands as shown; then screw the wire holders back on.
A
Note:
When inserting the stripped ends of the speaker cords as shown above,
make sure that at least 1/16 inch (1.6 mm) of insulation is inside the wire
holders (i.e. no exposed wire is visible) and that no loose conductor wire
strands are protruding after the connection is made. To prevent speaker
wires from loosening, make sure that the wire holders are firmly screwed
in.

Banana Plug connections are also possible. Simply insert the Banana P
