Clip warning

When a high-level signal exceeds the maximum 

capability of the unit, the signal  is automatically 

compressed (clipped) in order to prevent 

damages to the system circuitry. When clipping 

occurs in one or both channels, a warning 

message is shown in the Alphanumeric Display. 

Table 2 describes the possible messages for 

clip warning.

            Table 2: Clip warning messages

If clip warnings often appear in the 

Alphanumeric Display, try to reduce the signal 

level to prevent audio distortion. A real-time 

spectrum analyzer, such as the i7600 RTA 

Module, is the ideal tool for identifying the 

frequency that is being clipped. The i7600 

can also help you ? nd out whether the clipped 

signal is at the input (

Pre EQ

) stage or the 

output (

Post EQ

) stage.

EQ/RTA switch and indicator

Pressing the 

EQ/RTA

 button lets you switch 

between the EQ Module and RTA Module. The 

accompanying green LED lights up when you 

are in the RTA Module.

Bypass switch and indicator

Pressing the 

Bypass

 button lets you switch the 

bypass function on or off. When a channel is 

bypassed, as indicated by the accompanying 

red LED, none of the EQ settings are applied 

to the input signal of that channel. As a result, 

the signal you get from the channel output is 

identical to the original input signal. This feature 

lets you make a quick comparison between the 

original and processed sounds. It is particularly 

useful when you are setting up your system.

NOTE: The 

Channel Link

 status affects the 

behavior of the 

Bypass

 button. When 

Channel

Link

 is on, pressing the 

Bypass

 button affects 

the bypass status of both channels. When 

Channel Link

 is off, however, which channel 

will be affected by the 

Bypass

 button is 

determined by the location of the cursor (that 

is, the blinking LED in the Band Level Display, 

or the left-most blinking LED in a multiband 

group). If the cursor is in the left pane, pressing 

the

Bypass

 button affects only the bypass 

status of Channel 1. Likewise, if the cursor is 

on the right pane, pressing the 

Bypass

 button 

affects only the bypass status of Channel 2.

GRAPHIC EDIT control

The behavior of this control knob depends on 

the current control mode. Generally, this knob 

adjusts the band-speci? c settings. We will 

discuss this control in greater detail later.

FUNCTION EDIT control

The behavior of this control knob also depends 

on the current control mode. Generally, 

this knob adjusts the system-wide and

channel-speci? c settings. We will discuss this 

control in greater detail later.
