    Thanks Thank you for choosing the XTA DP6i for your application. Please spend a little time reading through this manual, so that you obtain the best possible performance from the unit. All XTA products are carefully designed and engineered for cutting-edge performance and world-class reliability.

  • Page 7: Introduction

    1U unit with extensive remote control capabilities. To achieve this, the DP6i has two inputs and six outputs which can be configured in five basic crossover modes – 3 x 2 way; 2 x 3 way; 4 way; 5 way; and 6 way.

    Pressing the Mute Unit key will instantly silence all outputs, but all metering will continue to function.

  • Page 13: Interface Operation Guides

    Interface Operation Guides As the DP6i has been designed primarily for installation purposes, the choice of which remote interface to use is very important. This section explains the different interface options and how to choose the best one for your application.

  • Page 14: Rs232 Connection (Single Unit)

    A typical interface set-up might involve running an RS232 link from laptop or a desktop computer to a DP6i set up as a master unit. The diagram below shows this method of connection, the required menu options are also given. Note that the RS232 cable must be a 1-1 connection type, NOT a null modem cable (which has connections crossed internally).
  • Page 15 RS232 Connection (Multiple Units) If control over multiple units is required, typically the slaves will be set up to run from the RS485 ports on the master DP6i. Note the incremental ‘ID NUMBER’ option in the unit’s setup. DP6i Operators Manual...

    What this means is that the distance from the first RS485 output to the last RS485 input must not exceed 1km in total. Cable’ ‘01’ + Cable ‘02’ + …Cable ‘NN’ < 1000 metres Page 16 DP6i Operators Manual...

  • Page 17: Rs485 Connection

    RS485 Connection To use RS485 communication directly from a computer, a master DP6i must be configured to receive RS485. You must have a suitable RS485 port on your computer, or a converter connected to the serial port in use. This configuration is shown below, along with the required unit setup.

  • Page 18: Midi Interface

    All other program changes sent to the unit will have no effect. Midi Connection To use MIDI communications, the DP6i must be configured to receive as a master via its MIDI port. You must have a MIDI card or interface connected to your computer or suitable device.

  • Page 19: Gpi Interface

    GPI Interface In certain circumstances the connection of a computer to a DP6i is both impossible and undesirable, perhaps for reasons of unnecessary complexity and cost. This is where the general-purpose interface option becomes useful. It permits the recalling of memories (input, crossover, or both) from a remote location, without the need for expensive interface controllers.

  • Page 20: Locking The Unit Remotely

    Locking the Unit Remotely Supplied with the DP6i is a remote locking program. This allows all the connected units to have their front panel controls locked out, including the Mute Unit key and the Quick Memory Recall keys. Starting the program will display a window as shown below.

  • Page 21: Dp6I Configurations

    DP6i Configurations Introduction To simplify the set-up of the DP6i, 5 crossover modes are selectable. These all have parametric equalisers, high and low pass filters, gain controls, delay and limiters. The following set of diagrams detail how each of the five modes is internally configured.

  • Page 22: X 3 Way

    This gangs outputs 1 & 4, 2 & 5, and 3 & 6, so that they track identically. Any changes made to the crossover points or EQ will not be affected by swapping from pre to post or vice versa. Page 22 DP6i Operators Manual...

    This configuration also allows all the input EQ to be moved to input A, giving 16 bands of fully parametric EQ. If there does not appear to be any EQ on input B, this will be why. DP6i Operators Manual Page 23...

    Output 6 - Analogue output 6 only Note that the internal sampling rate of the DP6i is 48kHz. When the analogue in to digital out route is chosen, the output sample rate will therefore be 48kHz. This cannot be changed. When using a digital input, however, the DP6i will lock to any sample rate from 32kHz up to 48kHz, and this will be the outgoing sample rate as well.

  • Page 27: Operating Notes

    Provision is also made for separately isolating each input and output shield pin permanently within the DP6i by breaking the appropriate PCB track, where marked with a box and an arrow next to each XLR connector using a small drill bit or cutter.

  • Page 28: Crossover Filter Slopes

    Time Alignment A further advantage of the DP6i over conventional products is the provision of an independently adjustable delay section for each output. This allows the true arrival time from multiple drivers to precisely aligned rather than relying on the compromise 'phase adjust' approach.

  • Page 30: Setting Accurate Limiter Thresholds

    Setting Accurate Limiter Thresholds The limiters built into the DP6i are intended to be used for loudspeaker driver protection, as opposed to amplifier protection. All modern professional power amplifiers designed for live sound use have their own limiters, which are tailored to protecting the amplifier from clipping.
