includes ±15 dB bandpass gain and polarity
control.
Output EQ: 8 parametric fi lters per channel with
adjustable Q, ±15 dB boost/cut. This 8-fi lter
EQ section can NOT be bypassed. Filters are
enabled individually.
Output Limiter: Prevents clipping and protects
loudspeakers. Choice of –3, –6, or –12 dB
threshold per channel.

are factory-set for JBL Cinema systems. Four
are user-defi nable.
Front Panel Controls and Indicators
Level: Detented rotary level control, one per
channel.
Power Switch: On/off switch applies AC power
to the amplifi er.
Sel/Prev/Next Buttons: Three buttons near the
LCD screen are used to access menu items and
front panel lockout.
LCD Screen: Backlit liquid crystal display
shows speaker presets and signal processing.
Signal Indicator: Green LED, one per channel,
illuminates when a very low-level signal is
present at input.
–10 Indicator: Green LED fl ashes when output
signal exceeds –10 dB below clip.
–20 Indicator: Green LED fl ashes when output
signal level exceeds –20 dB below clip.
Ready Indicator: Green LED, one per channel,
illuminates when the amplifi er is ready to
produce audio.
Clip Indicator: Red LED, one per channel, turns
on at the threshold of audible distortion.
Temp Indicator: Red LED, one per channel, illuminates
under excessive temperature conditions.
Power Indicator: Blue LED illuminates when the
amplifi er has been turned on and has power.

Protection
CDi-Series amplifi ers are protected against
shorted, open or mismatched loads; overloaded
power supplies; excessive temperature; chain
destruction phenomena; excessive output
current, and input overload damage. They also
protect loudspeakers from input/output DC,
large or dangerous DC offsets and turn-on/
turn-off transients
