SM PRO AUDIO DI4V
/DI8
4- and 8-Channel DI/Line Mixers
Multi-function direct injection boxes and stereo
line mixers in one single unit rackmount chassis,
the half-rack SM DI4v and full-rack SM DI8
feature 4 and 8 channels of unbalanced to
balanced converters with 10dB pad and earth lift
selector provided per channel. They are suitable for
many applications right out of the box but it is the addition of a built
in line mixer (volume and pan control for each channel and master volume), that
makes them unique problem solvers. If you are a keyboard player, electronic drummer, PA/Studio
owner, pro musician or a hobby player, the SM DI4v or SM DI8 will find a place in your rack. Imagine running your
4 keyboard or modules on stage directly onto them and being able to send off balanced signal to the front of house rig
while providing your own dedicated monitoring mix...all on a single rackmount direct injection box/line mixer! SM
DI4v includes a headphone amplifier so you can monitor your own signal, the SM DI8 includes a LINK function so
that multiple units can be linked to a single stereo output. So if you have more than 8-16-24.... inputs of unbalanced
signal they can all be routed and monitored through the one output pair!
8/2 Tube Mixer
The M-3 is an 8-channel compact tube mixer, ideal for all tracking and mix-
ing applications. Each channel features discrete tube mic preamps, a 4-band
EQ with swept mids, 2 aux sends and a post-fader direct output for multitrack
recording. The master section has tube stages in the main mix bus, together
with 2 aux returns, monitoring, metering and an optional 24-bit/96kHz stereo
digital output.When linking multiple M-3 mixers, the stereo, PFL and aux
busses are also linked, providing an unlimited number of channels.
