Connections

Mounting the set on the rack

This set is attached the mounting brackets(left, right and bottom) and is shipped from the factory.
You can mount the set on the rack with using these brackets.
1. Install the set into the rack.
2. Fasten four supplied screws through the left and right brackets' screw holes into the rack to fix the
set to it.
• When rack-mounting the unit, allow enough free space around the unit for normal ventilation. This
should be: 10 cm at the sides, 15 cm behind, and 30 cm above.
• For normal ventilation during use, remove the rear of the rack or open a ventilation hole.
• If the airflow is not adequate, the unit will heat up inside and may cause a fire.
• This unit has ventilation holes at the top, bottom, and rear to prevent the internal temperature rising
too high. Do not block them. Blocked ventilation holes are a fire hazard.

Connecting the Audio Equipment

NOTE:

• Do not plug in the power cord until all
connections have been completed.
• When making connections, also refer to the
operating instructions of the other
components.
• Be sure to connect the left and right channels
properly (left with left, right with right).
• Do not bundle power cords together with
speaker cables. Doing so could result in
humming or noise.
• Do not turn up the volume when no turntable
is connected to the PHONO input terminals.
Doing so will cause humming or noise.
When not connecting a turntable, leave the
included short-circuiting pin plug plugged in.
Cautions on playing SA sources:
When regular speakers not compatible with SA
sources (DVD Audio discs, Super Audio CDs
and other sources including treble components
above the audible range), set the properties of
the player (DVD Audio player, Super Audio CD
player, etc.) for use with regular speakers (or
amplifiers).
The speakers may be damaged if the volume is
set too high when playing SA sources.
For instructions on setting the player, refer to
the operating instructions included with the
player.

Cable indications

The hookup diagrams on the subsequent pages assume the use of the following optional connection
cables (not supplied).
Audio cable
Analog terminal (Stereo)
(White)
(Red)
Pin-plug cable

Connecting the speakers

Connect the speaker terminals with the speakers
making sure that like polarities are matched (⊕
with ⊕, ⊖ with ⊖).
Connecting the speaker cables
1. Loosen by turning
counterclockwise.
Either tightly twist or terminate the core
wires.
2. Insert the cable.
3. Tighten by turning
clockwise.
NOTE:
When making connections, take care that
none of the individual conductors of the
speaker cable come in contact with adjacent
terminals, with other speaker
conductors, or with the rear panel and
screws.
NEVER touch the speaker terminals when
the power is on. Doing so could result in
electric shocks.

Speaker impedance
Use speakers with impedances within the ranges
shown below according to their usage conditions.
Speakers used
Impedance
4 ~ 16 Ω/ohms
A or B only
8 ~ 16 Ω/ohms
Both A and B
Note on speaker impedance
When using speakers with an impedance
below the designated value (for example 4
Ω/ohms), playing for long periods of time with
the volume high could cause the temperature
to rise, activating the protection circuit.
When the protection circuit is activated, the
output to the speakers is cut off and the power
indicator blinks. If this happens, unplug the
power cord, wait for the set to cool off and
improve ventilation around the unit. Also check
the wiring of the input cables and the speaker
cable
cables. After doing this, plug the power cord
back in and turn the unit's power back on.
If the protection circuit is activated again even
though there are no problems with the wiring or
the ventilation around the unit, switch off the
power and contact a DENON PROFESSIONAL
service center.
