for Surround
In many cases both insert sections won’t
be wired to external devices. This doesn’t
mean that both insert sections can’t be
used effectively. An unused insert section
could be configured to perform a special
mute. An example would be to configure
insert 2 to mute the surround channels,
leaving only the front channels active.
This would give an operator a quick way
of checking the effectiveness of the sur-
round information on the overall mix.
Monitor Output Mode
While the Model 58 Central Controllers
support the connection of two sets of
monitor loudspeakers, often only the A
output will be used. The monitor output
A/B select button on the Model 59 Control
Console can be disabled, preventing an
operator from selecting output B. Only the
A LED will be lit, and the button will be
inactive.
Power-up Mute Mode
By default, upon application of AC mains
power the monitor outputs remain muted
until a power-up sequence has been
performed. Then the monitor outputs are
returned to their respective states as left
at the time of the previous loss of AC
mains power. There may be special uses
where having the monitor output channels
remain muted until an operator manually
presses the mute all button is desired.
Use the configuration button to select the
desired power-up mute-all operation.
Channels Selected for Bypass
Each monitor output channel can be
configured to either mute, or connect to its
associated bypass input signal when the
bypass function is active. How the chan-
nels are configured simply depends on
which bypass input channels have signals
connected to them.
A special mode has been included to allow
the bypass function to be disabled from
operation. To disable the bypass function,
simply select all output channels to mute
during bypass. The factory default configu-
ration has the bypass function disabled.
Bypass Mode
The bypass mode can be configured to be
operated in one of three modes: Monitor
output A only, monitor output B only, or
follow the state of the monitor output A/B
button. The first two modes cause their
respective monitor outputs to be active
when in the bypass mode.
Note that even if the monitor output mode
is configured for A only, setting the bypass
mode to monitor output B only will cause
monitor output B to become active when
the bypass mode is active. Also, when the
bypass mode is configured to follow the
A/B button, the monitor output mode must
be configured to allow A/B operation or
only monitor output A will be enabled
during bypass operation.
Reference Level
For audio-with-picture applications it’s
critical that mixing be done in reference
to a known monitor loudspeaker level. This
is often referred to as mixing to “85dB” on
the monitors. The Model 59 Control Con-
sole allows a precise monitor output level
to be stored, and then enabled by pressing
the button labeled REF. Setting the refer-
ence level is very simple:
1. Set up a precision sound pressure
level (SPL) measuring device at the
desired listening location.
