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.
Features The D-5.5 is an 8 input, 19" rack mountable mixing console, featuring superior audio performance, system expandability, and unique "user friendly" design.

Direct Output: RCA. 1/4" phone jack, and electronically balanced XLR with ground lift switch. Channel on/off switch with LED indicator (orange). Writing block. Other Connections: 60 mm fader. L & R Cue input: 1/4" phone jacks. Cue switch. L & R Cue Buss output: 1/4" phone jacks.
Front Panel (D-5.5) INPUT CHANNEL (D-5.5) Phono EQ (RIAA) IN/OUT Switch (RIAA IN/OUT) This switch is available for input channels 7 and 8 only and is active when a turntable with magnetic type cartrige is connected to the Phono input channel. The switch is a "push-in push-out" type. The "out" position provides a flat frequency response. Tape/Source Switch (TAPE/SOURCE) This switch is provided for selecting the desired input signals.
Front Panel (D-5.5, D-5.5E) Group Assign Control 3 and 4 (GROUP LEVEL) This control determines the amount of a given input signal assigned to the group 3 and 4 via the group assign control. AUX 2 Control (AUX 2) This control determines the level of the input signal to be fed to the aux 2 buss. When in the center detent position the control is off, and no signal is assigned. Rotating the control counter-clockwise increases the amount of pre-fader/post-EQ signal assigned to the buss.
Front Panel (D-5.5) OUTPUT CHANNEL Level Control for Return to Group (RET TO GROUP, LEVEL) This control adjusts the level of signal from the AUX 1 return and AUX 2 return, or the EFF return and REV return. Cross-fate Control to Group (RET TO GROUP, X-FADE) With the return signal select switch set to the REV/EFF position, the EFF and REV return signal levels are equally assigned to the group buss. When the control is in its center, detent position.
Front Panel (D-5.5) Writing Block The name of the source signal can be written in with an erasable felt pen or grease pencil. Cue Switch (CUE) The switch permits monitoring the signal prior to the effect return level control. Group Fader (GROUP 1 - 4) The 60mm fader provides continuously variable adjustment of the group level to the stereo L and R busses, and the group output connectors.
Level Control for Effect and Reverb Return to Aux 1 (REV/EFF TO AUX, LEVEL AUX 1) This control governs the amount of reverb signal (built-in or outboard) returned through the reverb return jack (REV RET), and effect signal returned through the effect return jack (EFF RET) to AUX 1 mixing buss. The signals of REV RET and EFF RET are controlled simultaneously.
CAUTION - The ground pin on the AC plug should not be removed under any circumstances. If the D-5.5 must be used on an AC circuit with no ground or and open ground, then a suitable grounding adapter should be used and its ground terminal should be securely attached to a good earth connection. Failure to do so will result in increased noise and shock hazard. Reverb Return Jack (REV RET) This 1/4" phone jack is used in conjunction with the Reverb send jack to connect an outboard effects device (ie.
Front Panel (D-5.5E) * The names of the functions on the D-5.5E are specified below as function of the input channel on the D-5.5 is the same as the D-5.5E. Difference in functions are explained. Power LED indicator and Switch (POWER) The power switch alternately turns AC power to the D-5.5E "on" and "off". The LED indicator lights when the switch is "on".
Rear Panel (D-5.5E) * The names of the functions on the D-5.5E are specified below as connection of the input channel on the D-5.5 is the same as the D-5.5E. Difference in functions and connection are explained. RCA Pre Accessory Patch Points (PRE IN/OUT) Buss Link Connector (BUSS LINK OUT) This connector is used to link the D-5.5E Expander with the D-5.5. A six-foot connecting cord is included with the D-5.5E.

Rack Mounting Instructions The D-5.5 and D-5.5E are designed for either console or rack-mount use, using a pair of brackets (included). The following procedure should be observed for the rack-mount use. 1. Remove both side panels and armrest unscrewing and removing 6 screws. 2. Mount the brackets on both sides of the chassis, using the screws removed from the side panels. and blank 3. The rear panel should be interpanel changed to allow for easy connection when the D-5.5 and D-5.5E are rack mounted. a.
Procedure for Changing Internal Switch Setting NOTE: The internal switches have been provided for added versatility when using the D-5.5 and D-5.5E in a variety of applications. AUX 1 / AUX 2 SEND PRE/POST EQ SELECTION SWITCH: Each input features an auxiliary send control for use as either an additional effects send, or as an on-stage monitor send. You should note that the Aux 1 and 2 control are a "split" pot with the detent position (12o'clock) being the off position.
