    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 DSP 260 is a digital audio device – and digital clipping produces very unpleasant results, the Clip (red) LED should not light. If the DSP 260’s input does clip, reduce the output level of the connected mixer.

    5x20mm, T800 mA, L250 V replacement. Disconnect A.C. power before replacing a fuse. Before turning the unit back on, assess the condition of the A.C. receptacle powering the DSP 260. If fuses continue to blow, refer servicing of the DSP 260 only to qualified service personnel.
  • Page 13 The signal does not undergo any digital conversion or processing. These connectors are used to pass input audio to a second DSP 260 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 14: Installation

    Power Connection The DSP 260 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 DSP 260 must only be connected to a properly wired, three pin, grounded A.C.
  • Page 15 DSP 260 Un-balanced Input / Output Connections Un-balanced connections can be made to the DSP 260, 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.
  • Page 16 Input Level Adjustment The final step in setting up, installing and connecting the DSP 260 is to set proper input levels to the unit. The DSP 260 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).

  • Page 17: Editing & Operation

    The factory warranty for your DSP 260 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.

  • Page 18: Run-Time Mode

    During operation, the left and right input level meters display the signal present at the DSP 260’s analog and Digital inputs. The DSP 260 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 source.

  • Page 19: Output Gain Reduction Meters

    Each output channel has a four-segment function display for informational purposes only. For any given configuration possible with the DSP 260, 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.

    Value Up and Down buttons to select the field for each letter / symbol character. The DSP 260 provides the complete ANSI character set, including lower-case & upper-case letters, numerals and symbols. Pressing and holding the Value Up and Down buttons will scroll rapidly through the character set.

    5.10 Parameters The following section is a detailed description of every DSP parameter available in the DSP 260; grouped by DSP block, in order of the signal flow of the DSP 260.
  • Page 22 Value Up and Down buttons to navigate to the Input Hi-Pass screen. The first DSP block in the DSP 260’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 23 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 DSP 260’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 24 Keep in mind that the DSP 260 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 Frequency offers a selectable frequency range from 20.0 Hz to 20,000Hz. Hi-Pass/Lo Pass The DSP 260 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. (See above) Illustration 5.2: Here the HiPass Output 2 Crossover is set to Linkwitz-Riley 24dB with the frequency set to...
  • Page 27 0.40 to 2.00 Delay (Output Channels) DSP 260’s output delays can be applied to output channels OUT1 - OUT6 and can be used to compensate for the positioning of cabinets or speaker arrays relative to each other or the original sound source.
  • Page 28 Level parameters (-100.0dB to +6.0dB). Adjust the value by using the up/down VALUE arrows. Channel Limiter (Output Channels) DSP 260‘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 29 Limiter settings for your system and may result in system damage. If a non-Dynacord 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.

    DSP 260 6 Setup The Setup menu allows access DSP 260’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.
  • Page 31 DSP 260 Input This window is where the global input mode is set. Use the <SELECT> key to navigate to the MODE parameter. Use the up/ down VALUE arrows to choose between Analog and Digital input. LCD settings allow the user to adjust the contrast preferences of the LCD screen to compensate for different lighting conditions that may be encountered within different venues.
