6910 Oscillator, PFL & Stereo Aux module 7-3
Revision J2005-2 J-Type
:1415 %RDUG # OLJKWV # 2Q 2 2II
A simple toggle switch for turning the console illumination ‘on’ or ‘off’.
:1416 %RDUG # OLJKW # GLPPHU
A single potentiometer that controls the brightness of the console illumination.
:1417 6LQH # :DYH # 2VFLOODWRU # )UHTXHQF\ # VHOHFW
A rotary switch that allows you to choose one of the eleven frequencies that can be
generated by the Sine Wave oscillator.
The frequencies available are:
31, 40, 63, 100 and 500 Hz
and
1, 3, 5, 10, 12 and 16 kHz
:1418 2VFLOODWRU # 6RXUFH # VHOHFWLRQ
A three position toggle switch that allows you to select one of the three types of oscil-
lator sources available.
OSC Selects the Sine Wave oscillator
PNG Selects the Pink Noise Generator
XLR Selects the ‘OSC I/P’ connector mounted on
the modules rear panel
The internal Sine Wave oscillator is provided so that basic signal level line-up proce-
dures may be easily conducted. Similarly, the internal Pink Noise generator can be
used for basic loudspeaker to room frequency response checks.
The ability to connect an external oscillator source allows you to use the more spe-
cialized oscillator modules that are now available.
:1419 2VFLOODWRU # 2 2 3 # OHYHO # PHWHU
A 20 segment LED meter that reads the output level of the oscillator source selected
by the Oscillator Source Selection switch.
:141: 26& 2 31* # RQ 2 RII
Since the Sine Wave oscillator and the Pink Noise generator are capable of deliver-
ing very high output levels, there is always the possibility that cross-talk could be
introduced unnecessarily. For this reason, a toggle switch is provided so that the
internal oscillators can be switched ‘off’ when they are not being used.
:141; 2XWSXW # WR # FKDQQHOV
Press the CHANNELS switch to route the selected oscillator to the OSC/PNG bus,
for use with Input Channels.
Press the ‘~’ switch on the required Input Channels to use the selected oscillator as
the channel input signal.
