AUDIO LEVEL INDICATORS
ESE offers two basic versions of the “Digital” Audio Level (VU) Indicator. Each version
has a reference level (“0 dB”) adjustment and is optionally available in a rack mount
configuration with as many as six units mounted on a single 1 3/4” x 19” panel.
Features:
• Accurate
• Easy To Read
• Peak or VU Mode
• Simple Installation
• Attractive & Low Cost
• Low Power Consumption
The ES-214 (vertical mount) and ES-215 (horizontal
& rack mount) are “in-line” VU Indicators which
provide a purely digital representation of an audio
signal’s loudness. Each has identical
circuitry with fourteen LED’s (nine
green, one yellow and four red) that
display loudness at -25, -20, -15, -10,
-7, -5, -3, -2, -1, 0, +1, +2, +3 and +4dB.
Units are shipped in the Peak mode
unless otherwise specified, however,
Fast Averaging or Slow Averaging
(VU) can be optionally requested.
The ES-215 can be ordered on a rack
mount panel with one, two,three,
four or six units mounted on the same
panel.
The ES-216 is a small meter-sized unit which simulates
the “flying wand” effect of its “analog” counterparts.
The unit displays audio levels in ten discrete steps
(-20, -10, -7, -5, -3, -1, 0, +1, +2 and +3
dB) using three red, one yellow and
six green LED’s. It can be console or
panel mounted and is designed to fit
into the same opening as many of the
commonly used mechanical meters.
The rack mount options allow the unit(s)
to be mounted one, two, three or four
per panel. Either Peak or VU operation
can be specified, (the unit is shipped
in the Peak mode unless otherwise
specified).
