Vizio D-5.5E - Manual (Page 3)

General Description
The TOA D-5.5 is a 19" rackmount or console configuration, eight-input stereo mixer especially designed
for electronic music and sound. It is expandable to a 32-input mixing system, with group, stereo and
mono outputs, and 16 MIDI-THRU jacks, when combined with two D-5.5E 12-input expansion units.
The D-5.5 was designed to perform many different applications in broadcast, live sound reinforcement,
and recording environments.
The D-5.5 provides four Group outputs, and mixing busses for Aux 1, Aux 2, Effects, Reverb, and Cue.
System features include: Sum output selectable pre- or post-fader (St. L + R); two Aux sends, selectable
pre-EQ/fader, post-EQ/pre-fader, or post-EQ/fader; Aux returns to Groups 1~4 and Stereo L, R, with pan,
level and crossfade controls; an effects patching loop and an internal spring reverb effect are returnable
to the 4 groups, stereo L, R, and Aux 1 & 2, with pan, level, and crossfade controls; dual bargraph meters,
selectable to Sum/Cue or Stereo L/R; a Headphone output with level control, a Cue buss output with
level control, and a Cue buss input.
Each input channel features a writing block to identify the source; tape/source selection switch; cue
switch; 60 mm fader; pad and trim controls; two-color LED to indicate signal prescence (green), or
clipping (red); channel on/off switch with orange LED indicator; 3-band EQ (high and low shelving-type,
and mid peaking-type with frequency sweep control); two Aux sends, selectable pre- or post-EQ; reverb
send to internal spring reverb; effects send; and four group sends via two pan and level controls.
Each of the four Groups features level and crossfade controls for returning Aux and Effects signals to the
Group mixing busses, and a stereo pan for assigning Group signals to the stereo Left and Right mixing
busses. The four groups and Stereo L, R also feature dual-color signal prescence/clip LED indicators; an
on/off switch with orange LED; writing block; 60 mm fader; and cue switch.
The D-5.5 rear panel features an RCA tape input, a 1/4" phone jack, and an electronically balanced XLR
(with switchable 48-volt phantom powering) for each input channel. Each input also has separate pre
and post accessory patch points and a direct output. Input channels 7 and 8 are front panel switchable to
stereo RIAA inputs, for use with magnetic cartridge turntable.
Group 1~4 output connections are RCA and 1/4" phone jacks; each features separate pre and post
accessory patch points (RCA). Stereo L, R and Sum output connections are individual RCA's, 1/4" phone
jacks, and electronically balanced XLR's with ground lift switches. Stereo L, R and Sum outputs also
feature pre and post accessory patching jacks.
The MIDI jacks are also located on the rear panel. "A" or "B" MIDI inputs are assignable to four
MIDI-THRU outputs (expandable to 16), allowing the use of multiple MIDI instruments without the data
loss or delay that may occur when several instruments are connected serially through their internal
MIDI-THRU jacks. Each MIDI-THRU output is provided with a front panel mounted on/off switch.
Also on the rear panel are a Buss-Link connector for connecting D-5.5 Expander units, separate 1/4"
phone jacks for stereo L, R Cue buss input and outputs, Aux 1, 2 sends and returns, external Reverb send
and return, and Effects send and return; a push button circuit breaker, chassis ground post, and six-foot
AC power cord complete the rear panel.
The D-5.5 combines with one D-5.5E for 20-inputs or two D-5.5E's for 32 input channels. Both units can
be mounted in a standard 19" rack, or may be used in a console configuration by removing the rack ears,
rotating the rear panel 90 degrees, and attaching the included wooden side panels. The mixers are
finished in an attractive and durable gray enamel, with 3-color control identification markings.
