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

 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
