q AmpLink - INPUT RJ-45 connector that receives up to the first 8 digital audio channels from a Bose® AmpLink
product. The amp also supports a THRU path for daisy-chaining those 8 digital audio channels to other Bose
AmpLink products at a maximum distance of 10 m 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.
w AmpLink ERR LED - Solid yellow indicates muted audio from the mute connector. Blinking yellow indicates an error,
which will also mute the audio.
e AmpLink LNK LED - Solid green indicates normal operation.
r INPUT SELECT - Switch selects if analog or AmpLink audio inputs are used. The default state is analog. Only switch
settings when the amplifier is powered o.
t ANALOG INPUT - balanced and unbalanced line-level input connectors.
y AUTO STANDBY - If enabled (ON), the amplifier will go into standby mode after twenty minutes without an input
signal. If in standby mode and an audio signal is detected, the amplifier will automatically wake and amplify audio
within 0.7 seconds. The OFF position disables the feature.
u INPUT - The input can be set to either DUAL mono inputs or SUMMED to one mono input.
i OUTPUT - The output can be set to STEREO or MONO.
o REMOTE 1 Control - Sets the REMOTE 1 input to control both outputs (or zones) simultaneously (ZONE1+2), or
allows each REMOTE input to control its own output (ZONE 1). If only one remote is being used, then this switch
must be set to ZONE 1+2.
a 70V/100V - Sets the outputs 70V or 100V.
s CONTROLCENTER - RJ-45 input connector for the CC-1 ControlCenter zone controller, or the CV41 if connecting to
two non-ganged CC-1s to the ZA 2120-HZA. If the two CC-1s are ganged together, then the CV41 is not needed.
CAUTION: Do NOT connect this RJ-45 port to an Ethernet-based network.
d MUTE - Contact closure connection that upon trigger (short) will mute all outputs.
f OUTPUT TRIM - Allows for up to 40 dB attenuation of each loudspeaker output.
g OUTPUT - Two inverted 2-pin Euroblock connectors for loudspeaker connections. Outputs are not bridgeable.
