Thanks Thank you for choosing the XTA DP100 for your application. Please spare a little time to digest the contents of this manual (figuratively speaking), so that you obtain the best possible performance from this unit. All XTA products are carefully engineered for world class performance and reliability. -
Page 4: Introduction
Delay measurement mode simplifies set-up by allowing delay time for the sound system to be calculated. 2 inputs and 4 fully assignable outputs allow the DP100 to be configured for almost any application. Operating modes comprise: Mono 1 in / 4 out, Dual 2 in / 4 out , Stereo (linked) 2 in / 4 out and Split 1 in / 1 out + 1 in / 3 out. -

See operating section for detailed information. Parameter Control - This rotary encoder allows the selected parameter to be adjusted. The control is velocity sensitive to combine fine resolution, when required, with the ability to make larger changes to delay time quickly. DP100 Page 3... -

Delay Measurement: Allows delay to be measured for the sound system enabling the correct delay time to be applied using the DP100. See page 12 for more information. Memory Store: Allows up to 80 settings to be stored. ( 20 per configuration type). See page 11 for more information. -
Page 9: Preliminary Setup
Allows a 3 band parametric equaliser for each output to be accessed and adjusted. See page 9 for more information. Preliminary Setup The following procedure should be followed when first installing the DP100. Select correct unit configuration via menu. Set maximum input level (operating level ) via menu. -

Gain Key - Whilst this key is pressed all three EQ sections for the selected output are set to 'flat'. Releasing the key restores equalisation. Scroll Key - scrolls to the next filter section for previewing current parameters on the LCD display (and adjustment if required). DP100 Page 9... -
Page 12: Dp100 Equalisation Curves
DP100 Equalisation Curves The following response curves illustrate the wide range of control available using the DP100's output equalisers. Figure 1. shows the symmetrical boost / cut response of a single section at various gains. Figure 2. shows the range of filter Q's available. -
Page 13: Memory Store
Note A: The 80 user memories are organised into four banks of 20, One bank for each DP100 configuration. This eliminates the possibility of recalling a different configuration than that currently in use. Note B: All current parameters are stored in memory, including output gain, EQ on/off status and equalisation settings. -
Page 14: Memory Recall
To achieve this, the DP100 generates a repeated tone burst at one of three frequencies: 100Hz, 1kHz or 10kHz. This signal is sent via the selected DP100 output to a line level input for the chosen loudspeaker's electronics. A microphone placed at the required 'listening' position is connected via a suitable mic-amp to Input A of the DP100. - Page 15 1kHz and 10kHz). Enter key - Pressing this key initiates the measurement function. Note: To avoid instant acoustic feedback and possible loudspeaker damage, the microphone must be disconnected from the DP100 input before quitting Delay Measurement Mode. DP100 Page 13...

Page 17: Midi Operation
MIDI Operation The DP100 is supplied with a MIDI interface as standard. The unit can be placed in Off, Master and Slave modes In 'Slave' mode the DP100 will monitor MIDI messages on the MIDI input connector and will respond to 'program change' commands from either another DP100 (set in 'Master' mode), or a separate MIDI events controller by recalling a DP100 memory corresponding to the 'program change' number. -

Page 19: Operating Notes
With any audio signal processing equipment it is necessary to ensure adequate signal level is used through the device, to avoid sacrificing noise performance. The DP100 features a menu selectable choice of operating levels to reduce this problem, (see page 6). It is suggested that the operating level chosen should give adequate level to just light the 6dB LED on the headroom meter with maximum program level being used. -
Page 20: Warranty
This product is warranted against defects in components and workmanship only, for a period of one year from the date of shipment to the end user. During the warranty period, XTA will, at it's option, either repair or replace products which prove to be defective, provided that the product is returned, shipping prepaid, to an authorised XTA service facility.
