Source and Monitor Selection

OPERATION

The SOURCEbutton directs the signal from the Processor input

selection section to the DACand analog output stage. The source button must be depressed to listen to the selected input through the main audio system.

The MONITOR button routes the output of the component

connected to the digital tape loop input to the DACand analog output stage. This enables you to listen to the digital tape recorder output while recording.

PHASE SWITCH

The analog output phase of the REFERENCE64 can be changed.

In some recordings	the	master	tape was recorded out			of phase,
creating unusually	poor	sounding		recordings.		~
The REFERENCE 64	can	shift	the	absolute	output	phase 180


degrees	to correct for this anomoly. To change the phase from 0
degrees		to 180	degrees,	press	the	180 DEG button.		To	change
back to		normal	phase,	press	the 0	DEG button.	Utilizing		the

Phase Shifting can, in some instances, restore life to a previously dull sounding recording.

EMPHASIS LED

Emphasis is a recording technique that accentuates the treble region of recorded music. Discs and/orTracks that were recorded

with Pre-emphasis will cause the Emphasis LED to illuminate.

When the Emphasis LED is lit the appropriate complementary

circuitry (De-emphasis) is activated to provide a fiat output response.
