ble, though not advised, to assign the same numeric channel to
more than one surround channel.
Levels & Metering settings panel
The Levels & Metering panel selects the metering ballistics and signal
levels used in metering and error detection.
Meter Setting
Meter Type Selects the ballistics used for the bargraphs and for detec-
tion of OVERs in the program. Also sets the displayed meter
scale and unit. All commonly used metering standards are pro-
vided, along with two proprietary meters.
Fast Decay 0 s attack, 0.1 s decay.
Slow Decay 0 s attack, 1.5 s decay.
The following meter types reference the Alignment
Level setting (below).
VU <300 ms attack, 300 ms decay (IEC 60268-17). 0 VU at
the Alignment Level.
IEC I (Nordic PPM) 5 ms attack, 1.5 s decay (DIN 45406).
IEC IIa (BBC PPM) 0 to 7 numeric scale, otherwise the same as
IEC IIb.
IEC IIb (EBU PPM) 10 ms attack, 2.8 s decay (IEC 268-10).
DIN (German PPM) 1 ms attack, 1.5 s decay.
Levels
Max Analog In Sets the gain of the analog input, thereby setting the
maximum input signal level. Using the lowest possible value
maximizes the signal to noise ratio.
+28 dBu Recommended for professional equipment.
+22 dBu Recommended for consumer or other equipment with-
out the ability to 22 dBu output.
Clip Level Any level above this value for a channel produces a Clip error
and an indication on the channel’s bargraph meter. For analog
inputs, settings are 1 dBu increments below the Maximum Ana-
log In. For digital inputs, settings are 1 dBFS increments below
