Operating Manual - ne24.24M Matrix Processor 4 1. INTRODUCTION Thank you for your purchase of the Protea ne24.24M. The Protea ne24.24M Matrix Processor uses modular expansion cards to provide up to twenty-four channels of audio matrixing and processing, along with provisions for remote control and logic output.
5 Operating Manual - ne24.24M Matrix Processor 4. FRONT PANEL FEATURES 4.1 RS-232 Dataport The ne24.24M has two RS-232 dataports wired in parallel, one on the front panel and one on the back, for connect- ing to a computer for software control. See section 7.
Operating Manual - ne24.24M Matrix Processor 6 5. REAR PANEL FEATURES 5.1 Input Connections Balanced input signals are connected to the ne24.24M using the included euroblock connector.
7 Operating Manual - ne24.24M Matrix Processor To use contact closure switching, up to eight presets (1-8) mus t first be defined according to the needs of the installation. To use the mic input “Push To Talk” feature, select the “Push To Talk Mic” checkbox in the Protea NE Software’s mic preamp dialog box.
Operating Manual - ne24.24M Matrix Processor 8 5.8 Data In/Data Out Connection The Data In and Out connectors are used for connecting the ne24.24M to the Ashly WR-5 active wall remote controller or RD-8C.
9 Operating Manual - ne24.24M Matrix Processor 7. 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.
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.
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.
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.
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.
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.
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.
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.
17 Operating Manual - ne24.24M Matrix Processor 8.2f Output Compressor/Limiter A full function compressor/limiter is included on each out- put channel.
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.
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.
