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.
