Slate/Com Mic & Tone Oscillator
The 3-position Slate / Tone Switch controls both the slate microphone and the tone oscillator.

Slate Microphone

Slide the Slate / Tone Switch left to activate the slate mic. The green Slate Mic LED will illuminate to
indicate that the slate mic is active. Slide the Slate / Tone Switch left again to deactivate the slate mic.
Hold the Slate / Tone Switch left for 1 second to activate the slate mic momentarily (until the switch is
released).
The secondary slate function is accessed by holding down the Select encoder when using the Slate
/ Tone Switch. By default, the secondary slate function activates the slate mic to the COM Send
COM Setup). The primary and secondary slate functions can be swapped from the Setup Menu option
COMMS/RETURNS > Mic Toggle Switch.
Program audio is muted when the slate mic is activated. This behavior can be disabled (so that
program audio does not mute when the slate mic is activated) from the Setup Menu option
COMMS/RETURNS > Program Auto-Mute.

Internal Slate Mic

The default slate mic is the 664's internal slate microphone. The 664's built-in slate microphone is used
to notate scenes from the mixer location. Its audio performance is not suitable for critical recording ap-
plications; it should be used for documenting scenes and for communication purposes only.

External Slate Mic

An external microphone can be used instead of the built-in slate microphone. To use an external
slate mic, plug the mic into the TA3 Slate Mic input on the Left panel and adjust Setup Menu option
COMMS/RETURNS > Slate/Com Mic Source to Ext Mic (for dynamic microphones) or Ext 12V Mic
(for condenser microphones).

Tone Oscillator

Slide the Slate / Tone Switch right to activate the tone oscillator. Hold the Slate / Mic Switch right for
more than 1 second to lock the tone oscillator on. When the tone oscillator is locked on, slide the Slate /
Mic Switch right again to deactivate.
By default, tone will be sent to the Master Bus (L,R), its associated outputs, and all direct outs. Tone
can additionally sent to the X1 and/or X2 tracks. Access Setup Menu option SYSTEM > Tone Routing
to adjust this.

Alternate Slate/Com Switch

By default, COM communication is engaged by sliding the Slate/Tone Switch to the left
while holding the Select Encoder and normal slate operation is engaged by simply sliding the
Slate/Tone Switch to the left. This functionality can be reversed from the Setup Menu option
COMMS/RETURNS > Mic Toggle Switch.
