OPERATIONAL & APPLICATION NOTES
24
T/D (tape, direct): Tape return to monitor 1.
Comm. in: Comm. return level controlled by trimmer below.
‘PL’: Assigns PL to monitor 1 (Down = on)
Phones select: M = Mono
ST = Sereo
MS = Mid Side
Monitor
pots 1, 2, 3: To adjust level to phones 1, 2, 3 (stereo output). Caution: It is recommended to
set the ‘phones’ pot at minimum before wearing headphones. Then increase the
level to suit personal preference. The minimum total
load (impedance) per side is
25Ω. The (2) phones 1 jacks are in parallel, the combined
load should not be less
than 25Ω.
Meters Section:
Tape/Dir.: Tape, Direct to the meters
Meters 1, 2: Monitor AB channels (tape or direct) or PFL.
Meters 3, 4: Monitor either CD (tape or direct) or A1, A2.
(Also, Meter 4 can indicate the battery level. See meter bridge)
PFL momentary
switch: Meter 1 & 2 monitor the PFL signal selected on the input channels.
VU Meter: Responds to the average program level. The internal oscillator should be set for
‘0’ VU on the meter. This will correspond to +4 dBu on the XLR outputs. As this
is an average responding meter, the peak program level will not be indicated.
In general, the Nagra modulometer will indicate approximately ‘0’ dB for peak
levels if the line up tone is set at -8 dB modulometer. For feeding external
equipment with VU meters, the level should be set for ‘0’ VU on both the mixer
and the outboard equipment.
PPM Meter: Peak responding meter. The reference level for a 1 kHz sine wave is set for -8
dB. This corresponds to approximately ‘0’ VU, although the difference between
an average responding meter and a PPM meter will vary according to program
material. The rise and fall times are set to approximate the Nagra modulometer meters.
Output Faders: These faders should be left at the maximum position (ie: ‘0’) for optimum
headroom. All line-up tones etc., should be made with the faders in this position.
Return Trimmers: To adjust return levels to the phones and meters.
