Spectra-Vue; Specifications; Input Impedance - MCi JH-500 Series Manual

2. A Phase switch. The output phase of each EQ circuit
can be switched from zero to one hundred eighty degrees.
3. Each Equalizer is transformer coupled and is normalized
to have unity gain.
The transformers which couple the Input and the Output of each
of these Equalizers are located in the underbelly of the Desk.
These 8 transformers have not been previously assigned.
SPECTRA-VUE
The JH-35 Spectra-Vue module uses the Light Meters (or
Vu meters)
on the JH-500 Series Audio Desk to produce a large, readable
AUDIO SPECTRUM DISPLAY. It separates a MIX or a SOLO into
eighteen 1/2 octave bands from 45 Hz to 16.5 kHz and displays
each band on a separate meter. This Spectrum Analysis is made
in "real time" - AS YOU HEAR the program on your monitor.
SPEC I F I CATIONS:
INPUTS are switch selectable from 8 sources. Simultaneous
displays of any number of these inputs is possible:
1. The 4 Quad Busses.
2. The 2 Stereo Busses.
3.
2 Auxiliary sources.
(Routed through Patch Points).
In addition to the above
IN~UTS,
SOLO SELECT switches are
provided so that any SOLO available from the Desk may be
monitored in three ways:
1. Visually only.
2 . Both Audio and Visual.
3 . Audio only.
A visual AGC
(Automatic Gain Control)
switch is provided to monitor
the VISUAL DISPLAY LEVEL. Audio level is NOT affected.
INPUT IMPEDANCE is 10k ohms - unbalanced.
Meter signals from the JH-500 Series Audio Desk are routed
through the Spectra-Vue module so that a relay can switch a
meter to the output of each Filter circuit when the Analyzer
is in use.
