PROTEA NE SOFTWARE Ashly offers a powerful software interface for the Windows PC environment, as well as any PDA device running Windows Mobil 05, providing control for the ne24.24M Matrix Pro cessor, and many other Ashly digital audio proces- sors and power amplifiers. All controls are intuitively r[...]

Operating Manual - ne24.24M Matrix Processor 10 7.2 Connecting the ne24.24M to a computer using Ethernet Ethernet is the preferred data protocol for computer control. A standard RJ-45 jack is used for connecting directly to a PC, PDA, or 10/100 Base-T network. 7.3 Connecting the ne24.24M to a computer using the RS-232 Data port The ne24.24M is opti[...]

11 Operating Manual - ne24.24M Matrix Processor 8.1c Phantom Power +48V Phantom power for condenser microphones can be provided to individual channels by checking the <+48V Phantom Power> box in the preamp block for a given channel. 8.1c Push To Talk Mic This check box and drop down menu selects the back panel logic input to serve as a contac[...]

Operating Manual - ne24.24M Matrix Processor 12 on either side of the fre- quency center is boost or cut, whereas a larger "wider" bandwidth (lower Q) pro- duces an audible change to the overall tone of a signal. Parametric filters are best used to hunt down and elimi- nate problem feedback fre- quencies, add or remove a characteristic &q[...]

13 Operating Manual - ne24.24M Matrix Processor is 0 degree phase shift, at the All Pass filter center frequenc y there is -180 degrees of phase shift, and at high frequencies there i s -360 degrees of phase shift. Each input channel has an EQ On/Off button for all filters, and in turn each filter band has its own bypass button. The Flatten Curve f[...]

Operating Manual - ne24.24M Matrix Processor 14 8.1i Ducker A Ducker is used to attenuate the level of selected input channels when one or more "Trigger" inputs have signal present. Input channels can be set to one of four ducker modes: 1.) BYPASS - no ducking action applies. 2.) DUCKED PROGRAM - signal present on other "Trigger"[...]

15 Operating Manual - ne24.24M Matrix Processor 8.2b Hpf/Lpf - Crossover Bandpass or crossover func- tions on the Protea ne24.24M are available only on the output chan- nels. Every channel's crossover consists of a high pass filter (HPF) and a low pass filter (LPF), along with the frequencies and filter types used. Each output's cross- ov[...]

Operating Manual - ne24.24M Matrix Processor 16 Bessel These filters, as implemented on the ne24.24M, are always -3dB at the displayed crossover frequency. Bessel filters are used because they have a maximally flat group delay. Stated another way, Bessel filters have the most linear phase response. When a Bessel HPF and LPF of the same crossover fr[...]

17 Operating Manual - ne24.24M Matrix Processor 8.2f Output Compressor/Limiter A full function compressor/limiter is included on each out- put channel. A limiter is commonly used to prevent transient audio signal spikes from damaging loudspeakers, manage ana- log and digital recording levels, optimize broadcast levels, or "thicken" the so[...]

Operating Manual - ne24.24M Matrix Processor 18 Since there are no user controls on the ne24.24M, the only way to load presets is by using Protea NE Software to recall files saved on either the PC or the ne24.24M. The excep tion to this is through the use of contact closures or the Ashly WR-5 wall-mounted remote control. Contact closures can load p[...]

19 Operating Manual - ne24.24M Matrix Processor In addition to using a WR-1 as the control device, the remote level control feature can be used for relay activated muting of selected channels, as in a fire alarm application (see sec. 16). Note: Use Protea System Software version 6.1.4 or higher, and ne24.24M program version 1.5 or higher to allow a[...]
