DSP Section
Input EQ: 6 parametric fi lters per channel with
adjustable Q, ±15 dB boost/cut. Also adjustable
high and low shelving fi lters. This 8-fi lter EQ
section can be bypassed.
Crossover Filters: Highpass and lowpass
per channel. Butterworth 6/12/18/24 dB per
octave, Linkwitz-Riley 24/48 dB per octave. Also
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.
Delay: Up to 50 msec total delay per channel.
Presets: 20 presets. One is “DSP OFF.” Fifteen
are factory-set for JBL Cinema systems. Four
are user-defi nable.
Front Panel Controls and Indicators
Level: Detented rotary level control, one per chan-
nel.
Power Switch: On/off switch applies AC power to
the amplifier.
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 flashes when output
signal exceeds –10 dB below clip.
–20 Indicator: Green LED flashes when output
signal level exceeds –20 dB below clip.
Ready Indicator: Green LED, one per channel,
illuminates when the amplifier 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, illumi-
nates under excessive temperature conditions.
Power Indicator: Blue LED illuminates when the
amplifier has been turned on and has power.
Back Panel Controls and Connectors
AC Line Connector: NEMA 5-15P (15A).
Input Connector: Two 3-pin removable Phoenix-
type connectors each accept a balanced line-level
input signal.
Output Connectors: 4-position barrier strip with
connectors for dual loudspeakers or bridge-mono
loudspeaker.
HiQnet USB Connector: Type B, connects to a
HiQnet network.
HD-15 Connector: For cinema I/O compatibility
with DSi-8M System Monitor.
Protection
DSi-Series amplifiers 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 off-
sets and turn-on/turn-off transients
Construction

Regulatory Certifications
Other Applications
Note: All measurements apply to all models of CDi
Series amplifiers in stereo mode with 8-ohm loads and
an input sensitivity of 26 dB gain, 1 kHz at rated power
unless other otherwise specified. Specifications for
units supplied outside the U.S.A. may vary slightly at
different AC voltages and frequencies.
