Advanced Technology DSP Engine:
Two powerful Analog Devices’ SHARC DSPs with 32/40 bit floating point math delivers the raw computing power necessary to implement a complete multifunction audio processor. New discrete, 24 bit AD/DA converters sample the data at 48kHz assuring a wide dynamic range.
The Firmware can be updated in the field via the PC by re-flashing the unit with files downloaded from our web site.
White Instruments has manufactured filters of all kinds for over fifty years from a book of transfer functions that was closed in the mid 1930’s. Our reputation for manufacturing audio filters that sound good and industrial filters that work is no accident. The secret is having the experience to select the appropriate transfer function and circuit topology for the task, then rendering the filter with a great deal of attention to craftsmanship and detail. This tradition is carried to our digital implementations.
Parametric: The Q of the parametric filters can be adjusted between 0.1 and 100. They are asymmetrical— engineered to be wider in boost mode and not as peaky sounding. Their center frequencies are adjusted in 1Hz steps between 20Hz and 20kHz. Amplitude is adjusted between -70 and +12dB in
0.1dB steps. Use the high-Q parametric filters to surgically remove feedback and room ringing. There are enough of them to do a thorough narrow-band tuning job.
H-P / L-P / A-P: Band limit your entire system or individual crossover sections (outputs) with the high-pass and low-pass filters that can have responses from 6 to 48dB/octave in 6dB steps. Their -3dB frequency is set between 20Hz and 20kHz in 1Hz steps. All-pass filters are first or second order and provide extremely short delays for loudspeaker alignment. Their frequency is also set in 1Hz steps between 20Hz and 20kHz.
Shelving: Subjectively shape your program with the 6dB/octave high and low shelving filters. Their -3dB frequency can be set between 20Hz and 20kHz in 1Hz steps and their amplitude between -12dB and +12dB in 0.1dB steps. Shelving filters can also be used for CD horn correction.
Graphic Equalizer Filters: These are the symmetrical, smoothly summing, octave band and fractional octave filters that built White Instruments’ graphic equalizer reputation.
They are generated from data included in the firmware. One filter, a group, or an entire set, can be placed on any input or output. Their frequencies are fixed on standard I.S.O. centers between 20Hz and 16kHz, and their amplitudes are adjusted between -12dB and +12dB in 0.1dB steps.
Output Levels: Individual outputs can be muted and have their polarity reversed. The 4 or 6 output levels can be assigned in up to four groups with a Master Level to control all. The Master level may also be muted.
Labeling: Name labels can be applied to all inputs, outputs, crossover sections and memories. These user assigned custom names will be displayed throughout the setup process.
Logic Inputs & Logic Outputs: The new PARAMEDIC 48 incorporates an industry first logic input so that it can receive 5V signals to change its 8 memories or 31 presets. The signal received may even be from a logic output of a different branded product (e.g. automatic mic mixer, matrix mixer, etc.). White Instruments beats AES24 to the punch to become the first product to offer true interspecies compatibility. The logic input can also incorporate a simple contact closure switch for up to 5 preset selections. Each of the 31 logic input conditions can trigger one of the unit’s 31 logic output signals to trigger relays, light LEDs, etc. or start a chain of events in an external controller.
Optional Seven-Day Real Time Clock:
The Time Warp option can be factory or field installed and adds a high degree of automation to systems that need to be reconfigured on a fixed schedule (e.g. lower the PA level at 10PM). Up to seventy events can be programmed by simply selecting a time and one of the days of the week..
Time Warp works by triggering one of the unit’s 31 Logic Events. RS-232 and RS-485 Remote Control: All PARAMEDIC 48s can have several basic functions like input and output level changes, mute and memory and preset recall remote controlled through their RS-xxx interfaces by an external controller that can be programmed to send White Instruments’ protocol through an industry standard communications port.
A Pink Noise Generator is built-into the new PARAMEDIC 48 for sound system testing. When invoked, both analog inputs are disconnected from the unit and the pink noise inserted in their place. The noise level is adjustable in 1dB or 0.1dB steps over a range of -80dB to 0dB and can be switched on and off for each output making system checkout a snap!
Mute Relays: The PARAMEDIC 48 is equipped with mute relays on each output. Their normal, power-off state is open or mute. Audio signals will not pass during a power failure or while the units are booting. Individual outputs are muted by controlling these relays through White Windows 2 software or an external processor communicating over the RS-xxx interface.
