Installation applications for audio systems vary in their complexity, and many require sophisticated and flexible signal paths, while others will require only a very simple fixed-form processing path. The ProSys PS-8810 was designed specifically for the latter requirement where system designers require certain types of signal processing in an easily matrixable format. System design time is reduced because the DSP building blocks are already placed in the signal path ready to be configured. Once each signal has been routed or mixed, you‚'re ready to go!
The ProSys PS-8810 is appropriate for a comprehensive range of installations; from major sports facilities to even the smallest houses of worship, the PS-8810 can fill the need. It incorporates 32 user-definable Presets that can be selected from the front panel, IQ for Windows software, switch closure, or can be scheduled from its internal real-time clock/calendar. You can easily configure the PS-8810 for automatic room combining as well as "simple to use" wall station controls.
Integration with IQ Systems
The ProSys PS-8810 is setup and controlled using IQ for Windows™ software. This also supports Crown amplifiers, and so full system control and integration of processing and amplification is readily achievable via the IQ bus. Your PC can monitor and control both the amplifier status and signal processing/mixing.
Expanding the system with networking
ProSys audio channels can be networked using CobraNet™ card, available as an option or prefitted as the PS-8810C. Bundles of audio channels can be routed to further units and can also be processed along with a unit's own channels. This naturally allows the 8810 to be integrated and share audio with other CobraNet™ devices.
Signal Processing Elements
Each input path (A and B) has programmable DSP elements for:
- EQ Filters
Each of these elements may be enabled or disabled, depending upon the need, and parameters adjusted easily. There are an impressive 256 EQ filters available in the PS-8810, which can be assigned to one of seven different filter types.
Different filter types include Low-pass crossover Filter (1st-4th order), High-Pass crossover filter (1st-4th order), Parametric Equalisation (2nd order), Low-Pass equalisation filter (2nd order), High-Pass equalisation filter (2nd order), Low-Pass shelving Equalisation (1st order) and High-Pass shelving Equalisation (1st order).
Automixing functions include NOM (number of Open Mics) attenuation, Priority Ducking and Adaptive Gating processing. Mutes and Signal Phase the post-DSP Input path B channel, giving great flexibility in signal routing.
Presets & Scenes
On finalising the configuration and routing of your audio signals, store the design as a Preset. There are 32 presets available in the 8810, which may be recalled via contact closure from the control port, infra-red remote, or as a scheduled Event. A further feature is the 'segue' funtion that allows elegant level transitions between Presets.
To set up minor changes in DSP settings, eg equaliser and delay parameter values for a different venue function, you can store these adjustments as Scenes, which may be recalled by the methods described above.
The internal event scheduler is a sophisticated time control system integral to the PS-8810 that enables Preset or Scene recall at either a given time, or at different times according to a schedule you determine. This can be accomplished even without the PC connected and the internal clock in the ProSys can function for up to 45 days without power.
Once you have programmed the 8810, you can disconnect the PC and leave the unit to perform its duties as a standalone device.
Simple Control Ports
A multi-function control port implements analogue and digital interfacing for control and monitoring by external circuits. The PS-8810 has 16 control inputs and 16 control outputs along with power supply outputs and common ground connections. Switches or faders may be applied to the inputs to change presets or individual DSP parameters.
Additionally, 8 of the control inputs can monitor either digital or analogue signals. The control outputs can illuminate LEDs and perform other logic output tasks.
With a PC connected to the PS-8810 and running the IQ for Windows™ software, you then have full control over the PS-8810's parameters for system setup and then later as a compuet based online control system.
The PS-8810 can be controlled from an infrared handheld remote. Chosen parameters can be accessed in this way to give your users a simple control interface for non-technical operators.
