WOrkING WITH THE i7600

Controls and Display
the i7600 consists of two modules: Eq Module and
rta Module. the Eq Module has four control modes,
and the rta Module has three. the behaviors of the
control knobs and the displayed information on the
i7600 depend largely on which module and control
mode is being used. identifying your current control
mode is the key to master the behaviors of the
controls. table 1 is designed to help you learn how
to identify the current control mode.
Band Level Display
the most prominent parts on the face the i7600
are the two wide panes of Band level Display. See
figure 1 for an illustration of the front panel. the left
pane is for displaying frequency and level information
of channel 1, and the right pane is for channel 2.
inside either pane are 0 columns of lEDs that
represent the 0 iSo-standard bands of the
audio spectrum in 1/-octave intervals. Directly
below every column is a number that indicates the
center frequency of the band.
Alphanumeric Display
Between the two panes of Band level Display is
a two-line alphanumeric lcD. what information is
shown in the alphanumeric Display largely depends
on the current control mode. there is, however, a
closely followed rule: the upper line displays the
system-wide or channel-specific status, whereas
the lower line provides either the band-specific
information or the names and values of various
functions.

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.

clip1 clipping at channel 1
clip2 clipping at channel 2
clip1+2 clipping at both channels
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 find out whether the clipped
signal is at the input (Pre EQ) stage or the output
(Post EQ) stage.
