T/D
(tape,
direct):
Tape return is also selected by the AB/CD switch.
Comm. in:
Comm. return level controlled by trimmer below.
‘PL’:
Assigns PL to phones 1 (Down = on).
Phones
select:
M = Mono.
L = Mono to left and right capsules (either A, C or A1).
R = Mono to left and right capsules (either B, D, or A2).
M.S.:
Mid, side decoded to L, R stereo, phones only.
Phones 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 25
!
. The (2) phones 1 jacks are in parallel, the
combined load should not be less than 25
!
.
Meter Section
T/D:
Tape, Direct.
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:
Meters 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 (eg: ‘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.
