2.9.3 Bridge-Mono 16/8 Mode

CAUTION: Never change the position of
the Mode Switch while the amplifier
power is on.
Typical analog input and output wiring, along
with level control and Mode Switch settings are
shown in Figure 2.11. Make sure the Mode
switch is set to the "Bridge 16/8" position.
INPUTS: Connect input wiring only to the lower-
(odd-) numbered channel pair.
OUTPUTS: Connect the speaker across the
posi tive terminals of each channel pair. Do not
use the negative terminals of the channel pair
when the pair is being operated in Bridge-Mono
mode.
NOTE: When operating the channel pair in
Bridge-Mono mode, turn down (full CCW) the
level control for the higher (even)-numbered
channel of the channel pair. The lower (odd)-
numbered level control works both channels.

2.9.4 Bridge-Mono 100V Mode

CAUTION: Never change the position of
the Mode Switch while the amplifier
power is on.
Typical analog input and output wiring, along
with level control and Mode Switch settings are
shown in Figure 2.12. Make sure the Mode
switch is set to the "Bridge 100V" position.
INPUTS: Connect input wiring only to the lower-
(odd-) numbered channel pair.
OUTPUTS: Connect the speaker across the
posi tive terminals of each channel pair. Do not
use the negative terminals of the channel pair
when the pair is being operated in Bridge-Mono
mode.
NOTE: When operating the channel pair in
Bridge-Mono mode, turn down (full CCW) the
level control for the higher (even)-numbered
channel of the channel pair. The lower (odd)-
numbered level control works both channels.

stan dalone or separate-network LAN.
HiQnet control is available over the CobraNet network
using Harman Pro System Architect software. The
soft ware can set up CobraNet audio routing and
addressing.

2.12 Audio and Aux Wiring

1. Connect the Audio Input Wiring. The amplifier is
equipped with removable barrier block connectors for
each channel's input. See Section 2.7 for more detail on
audio wiring.
In System Architect, the analog balanced audio inputs can
be set up to act either as CobraNet backup, an emer gency
override of CobraNet audio, or as an audio input to the
CobraNet network.
2. Connect the AUX wiring if used. See Section 4.1 for
more information.

2.13 Connect to AC Mains

Connect your amplifier to the AC mains power source
(power outlet) with the supplied AC power cordset. First,
connect the IEC end of the cordset to the IEC connector on
the amplifier; then, plug the other end of the cordset to the
AC mains.
WARNINg: The third prong of this connector
(ground) is an important safety feature. Do not
attempt to disable this ground connection by
using an adapter or other methods.
Amplifiers don't create energy. The AC mains voltage and
current must be sufficient to deliver the power you expect.
If the AC line voltage varies out of an acceptable range,
the amplifier's power supply turns off and the blue Power
LED flashes. The amplifier will turn back on when the AC
line voltage returns to safe operating levels. Fig ure 2.14
provides voltage limits for all amplifier AC volt age
configurations. Also, the amplifier must be run within the
specified mains frequency requirements (indicated on the
amplifier's back panel label). If you are unsure of the
output voltage of your AC mains, please consult your
electrician.
The various models have the following under-voltage
limits and over-voltage limits:

2.14 Startup Procedure

Use the following procedure when first turning on your
amplifier:
1. Turn down the level of your audio source.
2. Turn down the level controls of the amplifier.
3. Turn on the "Power" switch. The Power
indicator should glow.
4. Turn up the level of your audio source to an
opti mum level.
5. Turn up the Level controls on the amplifier
until the desired loudness or power level is achieved.
6. Turn down the level of your audio source to
its nor mal range.
If you ever need to make any wiring or installation changes,
don't forget to disconnect the power cord.
