In combination with the internal crystal-controlled daytime clock, this function provides real-time signal logging A visual tracing report on the signal present and dB limiting of the selected system, over the elapsed period of time. The presets can be tagged with a 21-character name.Īpart from the three processing sections, another important feature is the LimitLog™. Up to 99 user-presets can be made, consisting of factory system preset, gain, input-mode, equalising and delay, or a selection of each of these functions. Per channel there’s also a user-definable delay function The delay can be set from 1 to 294ms. The filters feature CSQ™ (Constant & Symmetrical Q), with a selectable Q from 0.3 to 15, in 36 steps. The equalising can be done through 4-bands of parametric equalising per channel Each band provides +12dB to – 19dB gain with a choice of 83 selectable frequencies. This sections offers user definable equalising and delay functions.

The optimization of the system’s response is taken care of by factory-set dedicated driver alignment and system configuration equalising a.o. The Intelligent Driver Guidance IDG™ processing offers optimized power response through “True-RMS” intelligent power limiting guidance and (separate) excursion limiting guidance.Ĭrossover filtering is done with “Von Helsing’s Filterslope Architecture” This filter design protocol consists of dedicated, hybrid Bessel, Butterworth or Linkwitz Riley responses. Simply select the correct speaker and speaker configuration and all parameters are set to give the best sonic performance Protection, dedicated filtering, optimised system response. This section provides system controlling and optimizing, with presets for all available Alcons systems and system configurations.
It also provides a signal routing matrix for configuring signal distribution over the 2 channels (input selection: input 1 or input 2 individual input 1 > input 2 input 2 > input 1 input 1 > inputs 1+2 input 2 > inputs 1+2, inputs 1+2 > input 1, inputs 1+2 > input 2). This section features channel-dependent gain control and mute function. The control of the DDP is done by a single “click & rotate” encoder with ergonomic, logical operation.
The sections consist of fixed, factory-set functions and variable, user-definable functions, with channel-dependent control. The Digital Drive Processor features three individual processing functions, all operating at the same time. The analog (single channel) SDP modules or the digital (dual channel) DDP module can be placed into the SDP slots, located in the front of the ALC.
The SDP™ circuit of the ALC can be seen as the “brain” of the amplifier Activating the DDP converts the ALC from a “standard” stereo power-amp into a dedicated amplified loudspeaker controller. The device offers a range of speaker-specific processing and controlling options, enabling the ALC to optimally drive the Alcons speaker systems.Įmphasizing Alcons’ “system synergy” philosophy, the DDP module with powerful 56 bit, 120 Mips DSP engine has been designed to offer intuitive control and utmost reliability while preserving the sonic excellence of Alcons’ pro-ribbon based sound systems. The Digital Drive Processor, DDP™, is an exchangeable signal processing device, which is complementary to the Alcons ALC controller-amplifiers.
