8 Introduction Thank you for purchasing the Electro-V oice DC -One Digital Signal Processor . The Electro-V oice DC -One Digital System Processor is a universal two-input, six -output digital signal p.
9 Owners Manual Matrix Router / Mix er • T wo (stereo) inputs • Summed left / right (mono) input • Six assignable outputs Outputs (each) • Cross-over (hi-pass / low -pass filters), with select.
10 Controls & Connection Front Panel 1 – USB Connector USB 1.0 port for connection to a PC running Windows XP or Vista. With a connected PC you may run the DC -One Editor Graphic User Interface Application. The DC-One can be oper ated, edited and configured for installation with an easy to use, intuitive interface.
11 Owners Manual 4/5 – Value Up/Down Buttons Depending on the current LCD screen, the V alue Up/Down Buttons performs the following function: Recall – Select forw ards/backwards through the stored preset list to select a preset to be recalled to current memory .
12 10 Store Button Pressing the Store button while in Run mode displays the Store Preset screen in the LCD displa y and the Store button lights. In this screen edited presets can be named and sav ed to a user preset location. Pressing the Store button again completes the preset save oper ation.
13 Owners Manual 17 – Output PEQ Button Pressing the PEQ button places the current preset in Edit mode and jumps to the first Output Par ametric Equalizer screen.
14 R ear Panel 24- A.C. Inlet The DC -One features a standard IEC A.C. inlet that will accept universal power cords. The DC -One power supply is auto-ranging and can accept voltages from 100 - 240V AC, 50 – 60Hz. Only A.C. cords approved for use in your country should be connected to the DC -One.
15 Owners Manual 28 – Balanced XLR Outputs Each output channel has an electronically balanced XLR connector for connection to system amplifiers. Each output channel can output different frequency ranges depending on its assignment and cross-o ver settings.
16 Installation For proper oper ation, all directions regarding installation and connection must be followed. Mounting The DC -One should be mounted in a rack -mount enclosure or rack r ails. The unit is 1RU tall by 14” (353mm) deep. Proper clear ance for air circulation around the unit must be provided.
17 Owners Manual Un-balanced Input / Output Connections Un-balanced connections can be made to the DC-One, although induced noise from cabling may be increased. Cables should also be less than 15” (5m) in length. Unbalanced connections can be 6dB lower in level as well.
18 USB Connecting the DC -One to a PC for operation via the DC -One Graphic User Interface application is accomplished via the front panel USB port. The port conforms to the USB 1.0. T ype B specification. T ype B USB cables are readily av ailable at computer dealers.
19 Owners Manual Editing & Operation F actory Presets The DC -One comes with 60 factory presets to configure and manage typical sound reinforcements systems. F actory presets can be recalled at will. Limited editing can be performed from the front-panel LCD user interface such as output level, mute and limiter threshold setting.
20 Run-time Mode LCD Display On power-up, the DC -One boots and displays the run-time screen. The current preset memory location and name are displayed as well as the configur ation on which the preset is based.
21 Owners Manual Output Gain R eduction Meters Each output channel has a four-segment gain reduction meter that shows the effect of the output channel Limiter on output level; from 0dBu to -12dBu. Output limiting can be bypassed by entering Edit mode, selecting Output Channel Limiter and selecting a limiter threshold of +21 dBu (8.
22 Make sure that the new preset is appropriate for y our system, and that connections to your system are correct for the current configuration. F ailure to do so could cause unexpected results or damage to the system or its components. T o exit the Recall process without loading a new preset, press the Edit, Setup or any of the DSP block buttons.
23 Owners Manual Edit Both F actory and User preset can be edited, but edited presets can only be stored in User preset locations. Standard Edit Mode The DC -One defaults to Standard Edit mode wherein, input and output channel par ameters are appropriately linked.
24 Input Channel Hi-Pass Filter Use the < Select > buttons to make the top line of the Edit screen activ e and the V alue Up and Down buttons to navigate to the Input Hi-P ass screen. The first DSP block in the DC -One’s signal flow is the stereo Hi-P ass Filter .
25 Owners Manual Input Channel Parametric EQ Use the < Select > buttons to make the top line of the Edit screen active and the V alue Up and Down buttons to navigate to the Input PEQ screen. The DC-One pro vides a stereo nine-band multi-mode filter generically referred to as the Input PEQ (Par ametric Equalizer).
26 Low -pass The Low-P ass filter determines the ultimate high frequency that your sound reinforcement system is allowed to reproduce; given the capabilities of amplifiers, speakers and transducers. The low-pass filter is useful for reducing excessive high frequency energy that can create stress on high frequency transducers and listener fatigue.
27 Owners Manual Hi-pass The Hi-P ass filter determines the ultimate low frequency that your sound reinforcement system is allowed to reproduce; given the capabilities of amplifiers, speakers and transducers. K eep in mind that the DC-One signal path already includes a hi-pass filter prior to the Input PEQ DSP block.
28 Input Delay DC -One offers an input delay that is useful for compensating for different arriv al times of sound originating from loudspeakers that are closer or further awa y from the listener than others.
29 Owners Manual Routing Input selections (In-A, In-B or In- A+B) can be applied to any or all of DC-One’ s six outputs. Choose a desired output channel from the output menu and press the Edit button to scroll to the Routing window using the V alue up/down arrows.
30 Frequency Frequency offers a selectable frequency range from 20.0 Hz to 20,000Hz. Hi-Pass/Lo Pass The DC -One Hi-Pass and Lo-Pass filters are determined b y selecting the Type from the list of par ameters, (see list above) and by choosing a frequency range between 20.
31 Owners Manual Output 1-6 Parametric EQ Band Type Frequency Slope Resp / Q Gain 6dB/oct. 12dB/oct. 6dB/oct. 12dB/oct. PEQ 20Hz - 20000Hz 0.40 to 20 -15.0dB to +15.0dB 6dB/oct. 12dB/oct. 0.40 to 2.00 6dB/oct. 12dB/oct. 0.40 to 2.00 ALLPS1 20Hz - 20000Hz ALLPS2 20Hz - 20000Hz 0.
32 Channel Level (Output Channels) The Channel Level is used to adjust master output levels. T o access the Channel Lev el screen, press the Level button found on the output processing menu. Subsequent button presses will toggle the display between OUT1 to OUT6.
33 Owners Manual Setup The Setup menu allows access DC -One’s global parameters on the LCD screen. This is where preferences for many functions can be set or adjusted.
34 Input This window is where the global input mode is set. <SELECT> key to navigate to the MODE par ameter . Use the up/down V ALUE arrows to choose between Analog and Digital input.
35 Owners Manual V = 331m/s + (0.6m/s/C) * T The speed of sound at room temperature is 346 meters per second. A t freezing temper atures sound travels at 331 meters per second. V is the speed of sound and T is the temper ature of the air . This formula finds the aver age speed of sound for any given temper ature (celcius).
36 System This window displays the firmw are version currently running on the DC -One. RS232 Port An RS 232 (DB-9 or ‘D-Sub’) connection is provided on the back panel to link to another DC -One to enable Master/Slave operation.
37 Owners Manual Configurations of the DC -One The DC -One offers 7 pre-defined configurations. A configur ation is a basic setting that includes the routing of inputs and outputs, the function of the outputs (Sub, Lo, Mid, Hi, Full R ange) including basic x -over filter settings, and different channel/ par ameter linking schemes.
38 Stereo 2 Way + Full Range This configur ation generally represents a 2-wa y stereo frequency crossover , where IN A serves as the left input channel and IN B as the right input channel. OUT 1 is the left Low-frequency output and OUT 2 is the left High-frequency output.
