The DS301 is designed for standard 19O rack mounting and occupies 1U of rack
space. Avoid mounting the unit directly above power amplifiers or power supplies
that radiate significant amounts of heat and always connect the mains earth to
the unit. Fibre or plastic washers may be used to prevent the front panel
becoming marked by the mounting bolts.
AUDIO CONNECTIONS
Both the input and output XLRs are balanced, the wiring convention being: pin 1
ground, pin 2 hot and pin 3 cold. The system is optimised for +4dBu operation in
accordance with pro-audio requirements. For use with unbalanced systems, pin
3 on both the input and output XLRs should be grounded.
Side-chain access is made via stereo jacks wired tip-return, ring-send. The return
input may be used on its own for external triggering of the gate. For external key
input it is recommended that a stereo jack is used with its ring terminal
unconnected.
If earth loop problems are encountered, do not disconnect the mains earth but
instead, try disconnecting the signal screen on the cables connecting the DS301
to the patchbay. If such measures are necessary, balanced operation is
recommended.
MIDI CONNECTIONS
Two standard 5 pin MIDI sockets are fitted to the rear panel of the DS301. The
Input socket should be sent MIDI data from a sequencer, a keyboard or a MIDI
controller. This data is always 'echoed' at the MIDI Output socket, rather like a
normal MIDI Thru socket on equipment with three MIDI sockets. The MIDI data
generated by the DS301 is also transmitted from the Output socket, merged into
the MIDI data copied from the Input socket.
