XTA DP324 SIDD Digital dynamics, used, but in good condition. SIDD is a powerful DSP based audio processor, ideally suited for live sound applications, where it combines the functions of a multitude of conventional products in a compact 1U unit. To achieve this, it has two inputs and two main outputs, together with two auxiliary outputs. Each channel has a six band parametric equaliser and delay line, a separate variable gain ‘A.D.T.’ delay and a harmonics generator, as well as four fully featured dynamics modules, designed to cope with all possible processing applications. Remote control is catered for in the form of MIDI, RS232 and RS485 ports, and multiple user memories are provided for the storage and recall of settings. Security lock-out is available for all controls. SIDD is also available with optional AES/EBU digital inputs and outputs. It has been designed for quick, intuitive adjustment through the use of multiple controls to provide an easy-to-use interface. Alternatively, it may be controlled externally by XTA’s proprietary WindowsTM software, along with up to thirty one other units. Features ♦ Superb audio quality – carefully optimised double precision signal processing coupled with a 40-bit internal data path ensures a dynamic range in excess of 110dB. The high sampling rate means minimal filtering providing exceptional sonic purity. ♦ A highly accurate 6 band parametric equaliser on each input, providing +15 to –30dB of gain at centre frequencies between 20Hz and 20kHz, with a wide range of ‘Q’s available between 0.4 to 128. All parameters feature fine resolution with 1/36 octave frequency steps, 0.1dB gain increments, and 100 ‘Q’ settings. Any parametric section can also be set to operate as a high or low shelving filter. ♦ A fully featured compressor with two bands of sidechain equalisation, and featuring variable knee and ‘look-ahead’ delay for absolute control. ♦ A noise gate / expander, again with dedicated sidechain processing – high and low pass filters plus two parametrics. The ‘look ahead’ design allows the gate to open before the signal arrives, completely eliminating clicks. ♦ A dynamic equaliser – compress or expand only the frequency band you choose, with unprecedented control and precision. TM DP324 Operators Manual Page 9 ♦ A delay line with separate ‘A.D.T’ module that may be routed to the auxiliary outputs. This allows for ‘staging’ of performers ‘front/back’ and ‘left/right’ of the soundstage. ♦ A ‘brickwall’ limiter with sidechain EQ and ‘look ahead’ ability for preemptive adaptation to signal peaks, and so complete prevention of overshoot. ♦ A harmonics generator to introduce controlled levels of second and third harmonic distortion, for simulation of ‘valve’ sound characteristics. ♦ Three velocity-sensitive encoders provide a familiar and intuitive control format with all filter information displayed simultaneously on a 2 x 24 character backlit LCD screen. ♦ The comprehensive standard specification also includes 256 memories, PC Card storage and remote control via MIDI, RS232 or RS485 ports, with security lock-out. ♦ AES/EBU digital input and output interfaces are available as an option. ♦ Input and output balancing transformers are also available as an option.
