Installation is quite simple:
•
connect an analog stereo line-level
output signal from the workstation to
the insert switcher main input
•
connect the insert switcher’s main
output to an analog input on the
workstation
•
connect up to three analog processing
or effects devices to the insert
connections
The following paragraphs cover an instal-
lation in detail.
The source audio signal connects to the
insert switcher input via two ¼-inch jacks.
One jack serves the left channel, the other
the right. Using phone plugs connect tip to
audio high (+ or hot) and sleeve to shield.
If the signal source is balanced it needs
to be wired in accordance with the
manufacturer’s recommended method
for unbalanced operation. In most cases
the source of the audio signal will be an
analog output from a workstation or
digital-to-analog converter associated
with a workstation.
Two ¼-inch jacks allow access to the
insert switcher output. Using phone plugs
connect tip to audio high (+ or hot) and
sleeve to shield. It is expected that the
output signal will be connected to an
analog input on a workstation or analog-
to-digital converter associated with a
workstation.
There are three sets of ¼-inch jacks that
are used to connect to the insert devices.
The sets are labeled Insert A, Insert B,
and Insert C. Each set contains two jacks,
one for left and one for right. Like many
recording and sound reinforcement con-
soles, each jack provides both a send (an

Insert Switcher
Of all the functions on the Model 60, the
insert switcher may be the most confusing
to understand and connect to—even us
here at the factory sometimes have trouble
explaining it to people! However, it is really
quite simple and, once you’ve connected it
into your system, we think you’ll find it a
very useful, timesaving feature.
The insert switcher is really just a set of
¼-inch jacks on the Model 60’s back panel
and three push-button switches on the
front panel. The insert switcher is entirely
passive; the audio signals don’t go through
any electronic circuitry.
The insert switcher’s design premise was
that it would be very useful for signals that
reside within a digital audio workstation to
be easily “processed” by one or more of an
engineer’s favorite analog devices. In most
situations only a small number of devices
are used frequently, such as a reverbera-
tion unit, tube-type equalizer, and dynamic
range processor. The insert switcher
eliminates the need to “patch” devices into
the audio chain.
Using the switcher is easy: with the work-
station interface (mouse, keyboard, or
control surface), route the signal to be
processed to and from the insert switcher.
Then use the switches on the Model 60’s
front panel to select which of the three
devices is active in the audio “chain.”
