I/O - THE SIGNAL PAGE

The setting of MIX and CH (channel) parameters, combined with the selected Routing mode (see page 18- 19), should be carefully considered to match the situation in which you use the M3000.

CH (Channel)

The Channel parameter selects which channels the M3000 are using for Input. The three possibilities are:

Stereo (STE)	- Signals on both Left and Right Input will be
	processed.
Left Input (L)	- Only the signal present on the Left Input will
	be processed.
Right Input (R)	- Only the signal present on the Right Input will
	be processed.

MIX

MIX - 100%. The Mix parameter of all presets will be 100%, meaning that no direct signal will pass through the M3000. The BYPASS keys will in this case work as mute in this case.

MIX - MIX. With this setting you can combine the dry signal with the effects. In this case the BYPASS key will work as a dry/wet switch.

Note: When the Engines are set to Serial Routing, the Mix parameter at Engine 1 will still be adjustable.

Status Bit

This selector changes the Channel Status bits of the Digital Output between professional and consumer format. When AES is selected, the M3000 will output the professional AES/EBU standard, and when S/PDIF is selected, the M3000 will output the S/PDIF consumer standard.

The default setting is AES/EBU but some Digital consumer products refuse to accept this professional standard.

In that case change to the S/PDIF consumer standard.

Example: If you are using a non-professional DAT machine as a receiver of the M3000 Digital Output, and you cannot make it accept the Digital Input, change the Status bit Output format from AES/EBU to S/PDIF.

Note: The different Status Bit standards do not affect the quality of the Audio Output from the M3000.

Dither

The M3000 can output dither from 8 through 22 bit resolution to off. The dither type is TPDF (Triangular Probability Density Function).

The M3000 is using internal 24 bit resolution and 24 bit A/D-D/A converters and dither is therefore only present on the Digital Outputs. It is recommendable to avoid using dither until the final stage of a production.

Usually you would put the finishing touch on your production with a TC Finalizer. If this is the case dither should be applied with the Finalizer - not the M3000.
