Owner`s manual

Features Overview
This chapter identifies and labels all the switches, indicators, connectors and functional
components with which a Ci owner should become familiarized. Getting to know the
items in this chapter and their locations on the Ci will make the subsequent chapters
in this manual much clearer. Keep in mind that this chapter is provided only as an
overview of the amplifier’s layout, and does not contain all the information necessary
to effectively operate the Ci. For more detailed information on many of the items
listed here, see
Chapter 4 – Amplifier Operation.

1
Rack Mounting Ears
Two mounting holes are provided on each front mounting ear.
2
Three-position AC Power Switch
With this switch in the “up” position the amplifier is “Active” (On). The middle position is
“Standby” (Off) and the lower position is marked Remote. When switched to Remote, the
amplifier must be activated by the sequential turn on/turn off (STO) circuit or NexSys software.
3
AC Power LED
The AC Power LED indicates the amplifier has AC power.
3
Active LED
The Active LED indicates the amplifier is “Active” (turned on).
4
Signal LED’s
Each channel has a Signal LED indicating that signal is present on that channel.
5
ACL/IGM LED’s
Each channel has an ACL/IGM (Active Clip Limiting/Instantaneous Gain Modulation) LED. If the
signal reaches the clipping point, this LED will light to show that ACL/IGM has engaged.
6
Fault LED
If the amplifier enters Protect mode, the output relay will open, and this LED will light.
7
Mute LED’s
Each channel has a Mute LED. If a channel is muted, this LED will light.
8
Fan, Grill & Filter Assembly
A high-efficiency DC fan draws cool air into the amplifier though the safety grill and removable
dust filter. Do not block this intake! The variable speed fan operates when the unit is “Active”.
Fan filters are easy to remove and should be cleaned regularly to ensure optimum perfor-
mance.
The power only breaks
one side of the AC mains.
Hazardous energy may be
present in the enclosure
when the power switch is in
the off position.

When operating in the bridged
mode, both attenuators must
be in the same position so the
speaker load will be equally
shared between the channels.
See the section on Bridged
Mono Operation for more
information and precautions.
