OPERATING INSTRUCTIONS
System Overview
The S-DMX is a dual independent channel microprocessor controlled digital audio
processor. It offers two completely independently delayed channels with precisely
controlled delay times. The delay times are adjustable without any sacrifice in the 18kHz
bandwidth which remains constant irrespective of the amount of delay selected. A total
delay of over thirty two seconds is possible with this unit, split over the two channels.
The design is highly modular and software based, allowing incorporation of new
technologies and techniques, therefore the system will not be rendered obsolescent as
developments take place.
Memory back-up is supplied as standard to ensure that entries to the microprocessor are
not lost on power down.
Both input and output levels are adjustable to accommodate units sending or requiring
non-standard signal levels.
An intelligently spliced de-glitched pitch change is included and is incorporated on both
channels. It will allow pitch shifting by as much as one octave either side of the original
frequency.
Regeneration controls are provided on both channels of the S-DMX and the input may be
switched to allow single line input (channel ‘a’ feeds both delay lines). A switch is also
provided to allow the outputs to be mixed for special effects.
An important feature is the use of ‘Nudge Buttons’. These buttons when used will cause
the delay to sweep up or down in steps of only 25µS making the sweep virtually silent.
Nudging of the pitch ratios and loop extremities is also available.
A facility for switching channel ‘a’ in phase or out of phase with the original and channel
‘b’ is provided.
A reset switch is provided for initialising the computer. A complete store clear instruction
(D0) is also provided.
A flight case is available for the S-DMX if required. Flight cases which accommodate
multiples of AMS Neve systems are also available.
The unit is engineered to the same high standard as the rest of the DMX range and offers
similar microprocessor controlled front panel facilities i.e. programmability,
repeatability and storage capability not available with other forms of data entry, putting
the engineer in complete control of the system functions.
The S-DMX is designed as a rack mounting unit 3.5”/2U high and 12.7” deep, excluding
knobs and connectors. The choice of components and quality of construction are of a
high standard and because of the choice of motherboard system with plug in circuit
cards and ribbon cables, maintenance problems are reduced to a minimum.
