Channel LED Bargraph Meter
The meter provides a 10-segment LED bargraph meter with
peak detection, plus a separate overload indication LED.
The 10 LEDs are utilised as follows:
● 6dB per segment in the lower region (-36 to -18dB)
● 4dB per segment in the middle region (-18 to -6dB)
● 2dB per segment in the top region for greater resolution.
0 VU is the centre of the meter scale and calibrated to a
nominal operating level of +4dBu.
Relative to a typical EBU AD/DA converter calibration of
+18dBu = 0dBFS, this means that +4dBu = 0 VU = -14dBFS:
As a result, a nominal operating level of 0 VU provides 14dB
of headroom in your digital recording platform. This is ideal for
most music sources which have crest factors of around 12 to
20dB.
[The crest factor is the difference between average (RMS) and peak level.]
CH METER SELECT
This switch selects the meter source globally across all 8
channels:
● INPUT - in the UP position, the channel input feeds the meter.
Signal is taken before the channel trim control (9) but after the
mic/line and DAW input selections (4 & 8).
● DIR OUT - in the DOWN position, the meter takes its feed
from the direct output. Thus, its exact location is determined by
the direct output routing (7) – see page 16.
This selection is overridden when displaying DAW
channel metering. (See the DAW Meters function
in the “Automation & Control Surface Manual”).
