XTA SIDD DP324 Dual-Channel Dynamics Processor
XTA SIDD DP324 Dual-Channel Dynamics Processor
SiDD is Seriously Intelligent Digital Dynamics – a powerful dual/stereo-channel dynamics processor for Front of House System Control, Channel Insert, In-Ear Monitoring, Stage Monitoring, Recording, Mastering and Broadcast, offering compressor, limiter, gate/expander, dynamic EQ, parametric input EQ, ADT’ harmonics generators, sidechain EQs, delay and instant recall factory user/presets, all in 1U.
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.
- 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 pre-emptive 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.
