The Model 591 Configuration Charts,
located at the end of this section, give
details on how each configuration param-
eter is set. An overview of the parameters
is provided in the following paragraphs.
Entering the Configuration Mode
A small button is located on the back of
the Model 591 Control Console, adjacent
to the 9-pin D-sub connector. Pressing
and holding this button for two seconds
places the Model 591 into the configura-
tion mode. In the configuration mode the
buttons and LEDs no longer perform their
normal function, but instead allow you to
observe and change many of the operat-
ing parameters. The mute/solo mode
LEDs light alternately to indicate that the
configuration mode is active. Once again
pressing and holding the configure button
returns the Model 591 to normal operation.
Note that configuration changes are stored
only after the configuration mode is exited
by pressing and holding the button.
Our apologies to those of you who find the
configure button a pain to use, but it’s
supposed to be that way! Seriously, the
top of the button is slightly recessed from
the back panel, making it harder to acci-
dentally activate.
When to Use the Configuration Mode
There is no problem frequently “tweaking”
the Model 591’s operating parameters to
achieve the desired performance. The
non-volatile memory chip used to store
the configuration is rated for thousands of
read and write cycles, and has a retention
time rated in years.
Insert Operation
Configuring the insert sections is an excel-
lent test of your manual dexterity. If you
have any doubts about your ability, don’t
chew gum at the same time! The insert
sections are unique in their ability to be
configured on a channel-by-channel basis.
Each channel of each insert section can
be independently set for one of four oper-
ating modes: Mute normal signal, maintain
normal signal flow, replace the normal
signal with the insert return signal, or mix
the insert return signal with the normal
signal. A detailed explanation of each
mode follows:
Mode 1: Mute normal signal. In this mode
no signal flows through the insert section.
This is effectively a channel mute function.
The insert send continues to be active, but
the insert return is not active.
Mode 2: Maintain normal signal flow. In
this mode the normal audio signal contin-
ues to flow through the insert section. This
is effectively a “no-insert function” function!
The insert send continues to be active, but
the insert return is not active.
Mode 3: Replace the normal signal with
the insert return signal. This is the conven-
tional insert function that most audio
consoles provide. The normal signal no
longer flows through the insert section.
The return signal is connected into the
signal path. The insert send continues
to be active.
Mode 4: Mix the insert return signal with
the normal signal. In this mode the normal
signal continues to flow through the insert
section, with the insert return signal mixed
(summed) with it. No level change is per-
formed, they are mixed at nominal level.
