Input functions such as automixing, phantom power, high-pass filters, and output assignments are selectable on individual channels. The DLA 93 AND 93TC includes capabilities for remote control of inputs and outputs, and linking of multiple units for system expansion or room combining. ® ?

Level controls affect signals sent to Main, Aux 1, & Aux 2 outputs, as well as Channel 1~8 Direct Outputs. [. . . ] Channels 5~8 are on bottom circuit board. 2) Move existing jumper (0 ohm resistor) to the vacant `POST' position (J103 to J104 for Channel 1; J203 to J204 for Channel 2; etc. ). 3) Solder both leads of each jumper, at the under-side of the circuit board. Channel Bus 1 & Bus 2 Pre/Post Jumpers: From the factory, channel signals assigned to Bus 1 are post-VCA (affected by automixing, compression, & remote control) and channel signals assigned to Bus 2 are pre-VCA (not affected by automixing, compression, & remote control). However, each channel may be individually modified to provide pre-VCA signal to Bus 1 and/or post-VCA signal to Bus 2. To convert Bus 1 to pre-VCA: 1) Locate jumper positions on the circuit boards, in the second group of resistors behind each channel High control (J107 & J108 for Channel 1; J207 & J208 for Channel 2; etc. ). Channels 5~8 are on bottom circuit board. 2) Move existing jumper (0 ohm resistor) to the vacant `PRE' position (J108 to J107 for Channel 1; J208 to J207 for Channel 2; etc. ). 3) Solder both leads of each jumper, at the under-side of the circuit board. To convert Bus 2 signal to post-VCA: 1) Locate jumper positions on the circuit boards, in the second group of resistors behind each channel High control (J105 & J106 for Channel 1; J205 & J206 for Channel 2; etc. ). Channels 5~8 are on bottom circuit board. A switch may be wired to multiple control terminals (to mute a group of signals). Multiple switches may be wired to a single control terminal, but if multiple switches are connected to multiple control terminals a diode matrix may be necessary (see diagram on next page). The combination of potentiometer & switch can be used to perform level adjustment & muting, or to provide an adjustable amount of `ducking' attenuation. Use of the DLA 93 AND 93TC Logic Outputs in conjunction with the Remote Control terminals can provide various `automatic' functions. Many other possible uses of the Remote Control terminals exist, which are not mentioned here. Two additional Remote Control terminals are provided, which allow master/slave assignment and selection of automatic/manual mixing. These terminals have internal pull-up resistors, which keep them at a high idle state of +5 Volts. Switches or other contact-closures are used to short these terminals to ground. The master/slave terminal provides the same function as the `slave' switch on the DLA 93 AND 93TC rear panel (see Master DIP Switches on pg. NOTE: The rear panel DIP switch must be in the down (`master') position for the Remote Control terminal to function. When multiple DLA 93 AND 93TCs are linked together, shorting the master/slave terminal to ground assigns the DLA 93 AND 93TC as a `slave' unit. [. . . ] The conference mic is not assigned to any output, but is for recording purposes only. A PNG200 provides noise-masking over the audience & jury areas during conferences. A DP/M28 distributes DLA 93 AND 93TC Main Output signal for media feeds, hearing assistance, and the sound system, which utilizes an EQ282M programmable equalizer, a CPA130 power amplifier, and two DT-2A autoformers. 13 Channels 1~8 Direct Out +24V Patch Trim (40 dB) Low High bus 1 exp.
