Dear Vision owner, Thank you for selecting the D&R Vision series. The Vision was created using the latest in computer aided design and assembling technology and incorporates the most advanced circuit components which results in the Vision being another D&R product unsurpassed in the electronics industry. We are confident that you will be using the Vision for many years and wish you much success.
Vision recording console The D&R Vision series is a 4/8 buss console designed to take the central role in a live/recording facility. The Vision is completely modular and can be configured to precisely suit your particular system requirements. To become completely familiar with your Vision and gain the maximum benefit from its use, we recommend that you read this manual thoroughly. It will provide important information about all aspects of the Vision including installation, operation, and servicing.
THE CHASSIS SYSTEM INTRODUCTION The Vision is available in three frame sizes; 19" (14 module positions), 38, and 46 module positions. The basic frame has two blank modules, both located on the extreme left and right of the frame. An exception is the 19" rack frame, which does not have blanks on either side. The extreme left and right blanks on the larger frames cannot be used for input modules as they conceal mechanical constructions.
2. THE MASTER STANDARD/DELUXE MODULES 2.0 Master section description The Vision has two master modules which are completely modular. All inputs and outputs are located on the back of the console. The paragraphs below give a description of each module section. 2.1 Control Room Monitor Section The Solo section is a soft switching circuit that automatically brings in the soloed channel when a solo switch is activated.
0dB on the meters equals +10dBu on the outputs! If V.U. reading led bars are ordered, they will have attack and release times of 300msec. and a +4 dBu level on the output connectors will give a 0 dB reading on the meter. Measuring the +4 dB output level of the channel or master with a AC voltmeter would give a 1.22 volt reading. The LED meter would actually be reading -6 dB on the scale. When monitoring program material, you will see higher levels on the peak reading meters. 2.
2.9 Master in/outputs The Vision can be interfaced with external equipment such as two track master machines, signal processors, headphone amps, and power amps. Interfacing is possible using the connectors on the master back panels. Listed below are all inputs and outputs for the two master modules. Partly the connectors are on the back panels of the modules. Some output connectors are mounted in the frame along with the MIDI interface connectors.
3. STANDARD MONO INPUT MODULES The Vision standard mono input module is a basic input design whereby all signal flow takes place from the microphone to the direct output as well as to the main left right outputs and group outputs. 3.1 Input section The input section controls all incoming signals from microphone and line inputs. A +48V phantom power switch for condenser microphones or direct boxes can be silently switched in or out of the circuit.
3.4 Channel assign / fader section The Channel assign section allows the user to assign to a maximum of 4 busses. The routing gives selection to the 4 group modules using two pushbuttons. With ach pair of summing amps, you have the choice of assigning to the odd or even groups using the pan-pot.
3.5 Input and Output connectors Every channel has the following connectors at the back of the housing. The balanced LINE input is a stereo 1/4" jack socket: Tip = hot Ring = cold Sleeve = shield The INSERT is on a stereo jack socket.

6.0 Stereo deluxe input module This stereo module is a flexible stereo module. This module can be used for stereo keyboards, drum machines, or any device needing two inputs on one fader. The paragraphs below describe stereo input module in full. 6.1 Input section The MONO switch lets you combine the two input signals into one output signal. It is also possible to feed one input signal to both outputs of the module.
The led bar is a peak reading 6 segment led bar following as a factory preset the post equalizer signal, thus indicating the incoming signal .The led bar can be set Post channel indicating the direct output level post fader. Note: This peak reading device indicates a -6 dB reading below actual level with a steady sinus tone. So when the internal level is 0 dBu, the meter will indicate -6 dB (The -3 dB led is on, the -10dB led is off) 6.6 Fader section The Vision has a high quality 100mm fader.

7.0 DUAL GROUP MODULE The Vision dual group output module is a basic output design whereby all signal flow takes place from the group summing amps to the group output as well as to the main left right outputs. 7.1 Return Section The return switch selects whether the input signal for the LEVEL pot is from the group output or from the RETURN A input on the back of the console. 7.2 Equalizer section This two-band fixed equalizer is very effective in its design.
7.7 In/output connectors. Every group module has the following connectors at the back of the housing. The INSERT "A" is on a stereo jack socket. Tip = return Ring = send Sleeve = shield The ground compensated GROUP output is a stereo 1/4" jack socket: Tip = hot Ring = cold Sleeve = shield Note: The default setting on this output is -1 0dB V, a setting of -+ 4dBu can be chosen on the channel (PCB) boards using jumpers.
8.0 MATRIX MODULE The Vision matrix output module is capable of making a sub mix from all or some group output signals and the left/right main output signal as well as an external input. 8.1 Matrix input control section The 10 input level controls receive their signals from the 8 group outputs and the main left right outputs. By turning up the level controls individually you can make a mix between several output groups and or the main output signals.
9.0 Instructions for operation The Vision is designed to be the perfect answer for multitrack and MIDI studios as well as live sound mixing. In order to get more familiar with the Vision, we shall discuss the entire recording process and divide it into five basic sequences. Sequence 1 through 4 are for the more conventional recording studios, and sequence 5 is for the MIDI studio. The session - Recording from microphone or line input onto the multitrack machine.
Effect Sends All unused aux sends can be used to send signals to signal processors such as digital reverbs, effects processors, and digital delays. The aux sends are usually post-fader in order that the right balance between untreated and treated signals is maintained however, it is possible to switch to pre-fader. Effects Returns In the modern recording or MIDI studios of today, there is a demand for many effect returns and inputs for MIDI related gear.
10.0 Installation - Electrical Local Electrical Voltage Before connecting the Vision, check the AC supply voltage setting by looking at the sticker on the back of the rack mount power supply. This should be 115V for use in areas with an AC supply between 100V and 120V, and 230V for use in areas with an AC supply between 220V and 240V. The main fuse is a 10 amp with a 250 volt rating.
the system clean. Connect stereo tape recorders (inputs and outputs), stereo headphone amp, and all signal processors. NOTE: MAKE SURE THAT YOU CHECK FOR HUM OR NOISE AS EACH INPUT OR OUTPUT IS CONNECTED. 10.4 Shields & Group Equipment The shield of any audio cable connection should be connected at one end only. If not, ground loops and high frequency cross-talk could result. Connect the shield as a general rule to the signal source (output) of anything.
