Tone Oscillator / Slate Microphone
A single 3-position switch controls both the tone oscillator and the slate microphone.
Tone Oscillator
Tone is used to set gain structure between the 442 and the next device in the signal path. The tone
oscillator uses the locking position of the switch.
By default, the tone oscillator is set to output a 1 kHz sine wave at 0 dBu to the outputs (with the
outputs set to Line Level). Tone is also sent at the same level to the direct outputs. In the Setup Menu,
the tone frequency and output level can be changed. Also, the tone oscillator can be removed from the
direct outputs or the tone switch can be defeated altogether.
The 442 oscillator contains a unique feature: the headphone output is attenuated by 20 dB when tone is
activated. This ear-saving feature can be defeated in the Setup Menu.
With tone active, press the battery check button to cycle the left output by 20 dB (used to verify left
vs. right output). Turn off the tone oscillator or press the battery check button again to stop the output
cycling.
Slate Microphone
The slate microphone is used to notate scenes at the mixer location. Its audio performance is not
suitable for critical recording applications; it should only be used for documenting scenes to tape. The
slate mic uses the momentary switch position. In the Setup Menu, a one second 400 Hz tone can be set
to precede the slate microphone.
The slate mic is sent to all outputs except the Direct Outs. In the Setup Menu, the slate mic can be
disabled to prevent unintended activation.
The slate mic can function as a communication mic in addition to its normal Slate Mic function. This
function is normally disabled and is turned on in the Setup Menu. In this mode, program audio at
the right secondary-master TA3 connector is disabled. Instead, the audio from the slate mic appears
when the RTN A/B switch is toggled. Normal program audio is unaffected. This function can be used
in conjunction with a Sound Devices MM-1 to create a fl exible communications system with a boom
operator.
