Level controls affect signals sent to Main, Aux 1, & Aux 2 outputs, as well as Channel 1~8 Direct Outputs. NOTE: Volume levels are also affected by an internal VCA (post-Level), which performs automixing, compression, & remote control at specified outputs. Channel Low & High Controls: These screwdriver adjustable controls set the tone for Channels 1~8 and the Aux Channel. [. . . ] 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. ). 2) Move existing jumper (0 ohm resistor) to the vacant `POST' position (J105 to J106 for Channel 1; J205 to J206 for Channel 2; etc. ). 3) Solder both leads of each jumper, at the under-side of the circuit board. Aux Input Bus 1 & Bus 2 Pre/Post Jumpers: From the factory, Aux Input signals assigned to Bus 1 are post-VCA (affected by remote control) and Aux Input signals assigned to Bus 2 are pre-VCA (not affected by remote control). However, the Aux Input may be 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 near the center of the top circuit boards, in front of the Aux Input connector (J903 & J904). 2) Move existing jumper (0 ohm resistor) to the vacant `PRE' position (J904 to J903). 3) Solder both leads of the jumper, at the under-side of the circuit board. To convert Bus 2 signal to post-VCA: 1) Locate jumper positions near the center of the top circuit boards, in front of the Aux Input connector (J901 & J902). 2) Move existing jumper (0 ohm resistor) to the vacant `POST' position (J901 to J902). 3) Solder both leads of the jumper, at the under-side of the circuit board. 4 OPTIONS Input Isolation Transformers Channel Direct Output and Bus 1 & Bus 2 Pre/Post Jumpers J408 BUS1 J407 PRE POST R106 T101 R104 Patch jack J406 BUS2 LED Input connector rear panel D OUT J405 J404 J403 POST Output Isolation Transformers Aux Input Bus 1 & Bus 2 Pre/Post Jumpers T10 J102 J202 T9 J103 J101 J201 J203 J904 BUS1 PRE J903 Expansion In connector rear panel DIP switches POST BUS2 J901 J902 5 REMOTE CONTROL The DLA 93 AND 93TC provides remote control terminals on a rear panel 15-pin Subminiature D (female) connector. 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. This is effective in room combining applications, where the sound system can be configured manually via a remote switch panel or automatically via contact-closures on the room partitions (see diagram on next page). The auto/manual terminal provides the same function as the `on' 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 (`auto') position for the Remote Control terminal to function. Shorting the auto/manual terminal to ground selects manual mixing (defeats automatic mixing). This is effective for selecting attended or un-attended operation of the DLA 93 AND 93TC (see diagram on next page). It is also possible to select automatic mixing (to manage increased inputs) only when multiple DLA 93 AND 93TCs are `combined'. 8 7654321 15 14 13 12 11 10 9 remote control remote control pin number channel 1 pin #1 channel 2 pin #2 channel 3 pin #3 pin #4 channel 4 pin #5 channel 5 pin #6 channel 6 pin #7 channel 7 channel 8 pin #8 aux channel pin #9 main output pin #10 aux 1 output pin #11 +10V pin #12 master/slave pin #13 auto/manual pin #14 ground pin #15 12 34 56 9 10 78 11 12 13 14 15 15-pin cable-end 6 REMOTE CONTROL Channel 1 Level Channel 1 Adjustable Mute 'Ducking' 8 7654321 15 14 13 12 11 10 9 25k linear 8 7654321 15 14 13 12 11 10 9 25k linear (trim) Channels 1~4 Group Level Channels 1~3 Multi-Priority Mute 'Page Override' 8 7654321 15 14 13 12 11 10 9 25k linear 8 7654321 15 14 13 12 11 10 9 mute 2~8 mute 3~8 mute 4~8 (mic 1) (mic 2) (mic 3) Main Output Level Automatic/Manual Mixing Switch 25k linear 8 7654321 15 14 13 12 11 10 9 8 7654321 15 14 13 12 11 10 9 DLA 93 AND 93TC (auto) (manual) Channel 1 Mute Master/Slave 'Room Combining' Switches 8 7654321 15 14 13 12 11 10 9 8 21 15 14 13 12 11 10 9 7 6 5 4 3 DLA 93 AND 93TC Room A (master) Channels 2~8 Group Mute 'Override' 8 8 7654321 15 14 13 12 11 10 9 7654321 15 14 13 12 11 10 9 DLA 93 AND 93TC Room B (master) Rooms A+B (slave) 8 21 15 14 13 12 11 10 9 7 6 5 4 3 DLA 93 AND 93TC Room C (master) Channel 1 Level & Mute DLA 93 AND 93TC Room D (master) Rooms B+C (slave) 8 7654321 15 14 13 12 11 10 9 25k linear 8 7654321 15 14 13 12 11 10 9 Rooms C+D (slave) 7 LOGIC OUTPUTS The DLA 93 AND 93TC provides eight logic outputs on a rear panel 9-pin Subminiature D (male) connector. Logic Outputs can be used to control external switching circuits (such as relays) for speakers, cameras, indicators, etc. The DLA 93 AND 93TC Logic Outputs are most often used, in conjunction with external relays, to turn off specific speakers when nearby microphones are active (reducing feedback problems). For example, if a speaker is located directly above microphone #1, the Logic Output for Channel 1 of the DLA 93 AND 93TC can be used to turn off that speaker relay when microphone #1 is active (see diagram on next page). The Logic Outputs can also be combined (wired in parallel) to control a single circuit. [. . . ] A DLA 93 AND 93TC provides automatic mixing for the courtroom microphones, and an input for playback of recorded evidence. For `off-site' arraignment, signal from a remote location is sent (via codec) to an input channel of the DLA 93 AND 93TC, and Aux 1 Output of the DLA 93 AND 93TC is sent (via codec) to the remote location. Aux 1 Output is assigned only courtroom signals, creating a `mix-minus' to avoid feedback of signals to the remote location. Two DMD modules, connected to the DLA 93 AND 93TC channel Patch jacks, provide summing and mic-level conversion of appropriate signals for the 4-track court recorder. [. . . ]
