    Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +3dBu (green) and / or +6dBu (Yellow) LED indicators. As the DC-One is a digital audio device – and digital clipping produces very unpleasant results, the Clip (red) LED should not light. If the DC-One’s input does clip, reduce the output level of the connected mixer.

    The button lights red as an alert. Press the Mute button again to restore the output channel’s signal. Output channels may also be muted from the DC-One Graphic User Interface Application, if the unit is connected to a PC. Muting a channel in any window of the application will light the channel Mute button on the front panel of the unit as well.
  • Page 15 The signal does not undergo any digital conversion or processing. These connectors are used to pass input audio to a second DC-One used as a slave or to other audio inputs in the system. 31 – Balanced XLR Inputs Each input has an electronically balanced, locking XLR connector.

  • Page 16: Power Connection

    Power Connection The DC-One must be connected to A.C. power only by means of the provided IEC A.C. cable or by a power cable provided by the dealer / installer to match the configuration of your country or region. The DC- One must only be connected to a properly wired, three pin, grounded A.C.
  • Page 17 DC-One 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. To match the audio level obtained with a balanced connection, it is necessary to tie pin 3 to ground at the XLR connector.

  • Page 18: Connection To Amplifiers

    Input Level Adjustment The final step in setting up, installing and connecting the DC-One is to set proper input levels to the unit. The DC-One does not itself have input level controls. Proper input level setting is accomplished by setting the output level from the (L / R) bus outputs from the connected mixer (or other audio output device).

    The factory warranty for your DC-One is 36 months (3 years), from the date of purchase. Please save the warranty certificate and receipt; which must be presented at the time of warranty service for the factory warrantee to be valid.

    Each output channel has a four-segment function display for informational purposes only. For any given configuration possible with the DC-One, an output channel may be identified as a sub, low, low/mid, mid, mid/hi, hi or full range output. One or two adjacent LED’s are displayed to indicate all possible output bandpasses.

    Both Factory 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 parameters are appropriately linked. (Refer to “Configurations” illustrations to see which channels are parameter-linked for each configuration.

    Value Up and Down buttons to navigate to the Input Hi-Pass screen. The first DSP block in the DC-One’s signal flow is the stereo Hi-Pass Filter. In any sound reinforcement system, the Hi-Pass filter is crucial for maximizing the efficiency and performance of the PA system.

  • Page 24: Input Channel Parametric Eq

    Each band of the Input PEQ can be configured for a specific filter mode, frequency, slope or Q and gain setting. Attention must be paid to the ultimate output gain through the rest of the DC-One’s audio path, as it is possible to boost frequency ranges to the point where the internal or external audio paths of the system may be clipped.
  • Page 25 Keep in mind that the DC-One signal path already includes a hi-pass filter prior to the Input PEQ DSP block. Settings to this filter in most configurations may be redundant or interactive with the initial Hi-Pass filter.
  • Page 26 Input GEQ screen. The DC-One’s input signal path includes a stereo 31-band graphic equalizer after the stereo 9-band PEQ in the signal path. This DSP block can be used for very precisely identifying, isolating and correcting problematic frequency ranges.
  • Page 27 The DC-One crossover routes frequencies to the appropriate drivers to accurately reproduce sound. The crossover network can also be used to insure that low-frequency energy is not accidently routed to the mid-range or tweeter drivers that may result in potential damage.
  • Page 28 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 by selecting the Type from the list of parameters, (see list above) and by choosing a frequency range between 20.0 Hz to 20,000Hz.

Channel Limiter (Output Channels) DC-One‘s output channel limiters prevent audio signals from exceeding a set level. Press the Level button to change the output channel. Hold-down the Level button for some seconds - you will then be presented with the Limiter screen.
  • Page 31 Limiter settings for your system and may result in system damage. If a non-Electro-Voice amplifier is used in the system, selecting “Other” from the amp list will allow the Threshold setting to be directly edited, however, the amplifier documentation should be consulted so you can calculate you limiter offset (if any) as needed.

    DC-One 6 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. Pressing the Setup button brings up the first Setup window. Use the VALUE up/down arrows to scroll through the Setup menu: Use the <SELECT> buttons to scroll to Setup parameters to make adjustments using the VALUE up/down buttons.
