Speck Electronics SSM - Manual (Page 43)

Chapter 4 Operation Section 38
Each input channel has four 1/4" jacks. The configuration of these four
jacks depend on whether your Model SSM is configured with mono
channels, stereo channels or a combination of both.
Each mono input channel has synth input, patch output, patch input, and
direct output jacks (from top to bottom). The synth input jack is the
primary input connector for most synth/samplers that have a low to
medium strength signal (-20dbu to 0dbu). With synth and samplers that
have higher strength signals (0dbu to +18dbu), the patch input jack may
be used. Using the patch input jack bypasses the synth preamp stage
and its synth trim control.
The patch output and patch input jacks provide line level interstage
access to the input channel before (pre) the equalizer and slide fader
control. This means that any device interfaced to these jacks will be
processed after the channels synth preamp and synth trim control, and
will not be affected by any adjustments by the equalizer, slide fader,
mute switch, or kill switch.
The insert jacks may be used to connect limiters, additional equalization,
noise gates, etc.
The direct output jack provides a line level signal for connection to the
input of a sampler or multitrack recorder. The direct output also
provides an interface to the Speck "Assign 28" subgroup module.
Stereo channels are configured with balanced left and right line input
jacks, and unbalanced left and right direct output jacks (from top to
bottom). This is the standard configuration for the stereo input channel.
The left and right synth input jacks will accommodate any stereo synth,
sampler, or line level signal. The two direct output jacks provide a
stereo line level signal to the input of a stereo sampler or the Speck
"Assign 28" subgroup module.
Connections to the balanced left and right inputs should be made
with a 1/4" T.R.S. (tip, ring, sleeve) plug. Connections to the
unbalanced direct outputs should be made with a 1/4" T.S (tip,
sleeve) plug.
