Output Attenuation controls:
Output attenuation controls for each output. Turn the controls clockwise to decrease attenuation and counter-
clockwise to increase attenuation.
The attenuator must be at 0 dB attenuation for the respective output to reach rated power.
w
Mute:
Normally open or normally closed dry contacts can mute all outputs. Mute polarity can be inverted by a
DIP
switch.
e
Output terminal block:
8-terminal block connector for loudspeaker connections. Each channel can deliver up to 300 watts regardless of load
into 4Ω, 8Ω, 70V, or 100V. Each output pair can be I-Shared.
r
DIP switches:
A bank of switches used to set amplifier configuration.
1. Auto Standby:
If enabled (
On
), the amplifier goes into lower-power mode after 20 minutes without an input signal. If in lower-power mode
and an audio signal is detected, the amplifier will automatically wake and amplify audio within one second. The default position is
Off.
2. Mute Polarity:
Switch mute polarity between
NO
(normally open) and
NC
(normally closed).
NO
is the default position.
3. Global Out:
Sets the output capability to
70V
or
100V
for all outputs that have their
DIP
switch set to
Hi-Z
. In 70V Hi-Z mode and Low-Z
mode, 100 V
P
and 70 V
RMS
limiters are automatically loaded. In 100V Hi-Z mode, 100 V
RMS
limiters are automatically loaded.
4. Output 1:
Select 70/100V high-impedance output (
Hi-Z
) or 4–8Ω low-impedance output (
Low-Z
) for
Output 1
.
5. Output 2:
Select 70/100V high-impedance output (
Hi-Z
) or 4–8Ω low-impedance output (
Low-Z
) for
Output 2
.
6. Output 3:
Select 70/100V high-impedance output (
Hi-Z
) or 4–8Ω low-impedance output (
Low-Z
) for
Output 3
.
7. Output 4:
Select 70/100V high-impedance output (
Hi-Z
) or 4–8Ω low-impedance output (
Low-Z
) for
Output 4
.
8. I-Share 1 & 2:
Deliver 2× channel power by combining the current of
Outputs 1 & 2
.
9. I-Share 3 & 4:
Deliver 2× channel power by combining the current of
Outputs 3 & 4
.
Note:
While the amplifier is off or in Standby mode, set one or both
I-Share DIP
switches to
On
and install the included jumper(s) across the first
four and/or last four terminals. Then wire the loudspeaker load(s) to the amplifier. Wire the
I-Share 1 & 2
loudspeaker load to the amplifier using 1+
and 1– (or 2+ and 2–). Wire the
I-Share 3 & 4
loudspeaker load to the amplifier using terminals 3+ and 3– (or 4+ and 4–).
t
Input Select control:
Dial selects if analog or AmpLink audio inputs are used. The default state is analog 1:1.
y
AmpLink ports:
Input
RJ-45 connector that receives up to eight digital channels from a Bose AmpLink product. The amp also supports a
Thru
path for daisy-chaining all eight digital audio channels to up to eight other Bose AmpLink products, at a maximum distance of 10 meters
between products.
CAUTION:
Shielded EIA/TIA 568B straight Cat 5 cable, or equivalent, is required for proper AmpLink operation. Unshielded cable is not
supported and may cause AmpLink audio to operate improperly. Do not connect either RJ-45 port to an Ethernet-based network.
u
Analog Input:
Line-level input for balanced analog audio signals.
i
Update port:
Used for firmware updates.
o
Gain/Sensitivity switch:
Slide switch to set global gain/sensitivity setting to high gain (–10 dBv sensitivity), mid gain (4 dBu sensitivity), or low
gain (14 dBu sensitivity).
a
Power input:
Power cord connection (IEC 60320-C14 inlet). Removing the power cord when the amplifier is on is an acceptable power-down method.
