Page 4: Introduction
Protea ne24.24M will more than satisfy requirements for any zoned system requiring input/output matrixing with signal processing. Factory presets for many typical sound install applications are available on the Ashly web site as a starting point to set your own system requirements. -
Page 5: Front Panel Features
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 7.3 for details on connecting to a computer. 4.2 Com LED This green LED lights for a few seconds whenever there is communication activity to the unit from a host PC. -
Page 6: Rear Panel Features
Operating Manual - ne24.24M Matrix Processor 5. REAR PANEL FEATURES 5.1 Input Connections Balanced input signals are connected to the ne24.24M using the included euroblock connector. A flat blade screwdriver is required to connect a stripped wire lead to the external connector piece, which is then inserted into the rear panel Euro Block receptacle. -

Operating Manual - ne24.24M Matrix Processor To use contact closure switching, up to eight presets (1-8) must 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. -

If, on the other hand, the ne24.24M needs RS-232 control while still in a networked ethernet system using Protea NE Software, add a 24.24M (not the ne24.24M) from the <Add Item> menu in Protea NE Software and set the unit up accordingly using the self-launching older Protea System Software. - Page 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. as a contact closure input channel engage.

- Page 13 Operating Manual - ne24.24M Matrix Processor An Autoleveler is a dynamics processor used to automatically boost or cut a signal to a user defined target level. TARGET LEVEL is the primary setting in an autoleveler, as it determines the desired constant level to which an input is boost or cut.

8.1k Remote Level Control Each channel can be remotely attenuated through the back panel 0-5V Remote Level Control pins, or by an Ashly RD8C active remote attenuator connected to the 4-pin data connector on the back. The Remote Level Controls dialogue box then allows arbitrary assignment of the remote’s attenuator channels... - Page 15 24dB/oct Linkwitz- Riley filters are the industry standard, the easiest to use, and the filter type recommended by Ashly. Other filter types are available, but may require polarity switching or other adjustments for proper results. The following paragraphs offer a summary of the three filter types as used in the ne24.24M crossovers.
- Page 16 Operating Manual - ne24.24M Matrix Processor 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.

10 REMOTE CONTROL Ashly makes three remote control options for the Protea ne24.24M. All of them are designed to be installed in a standard wall mount electrical box using a standard cover plate. The WR-1 and WR-2 are passive controls which can adjust volume or select presets respectively, while the WR-5 (replaces WR-3 and WR-4) is an active control with user defined function buttons and LED display. -

Level control is "attenuate only" meaning that the maximum setting of the control potentiometer (fully clockwise) results in 0 dB gain of the controlled channel. A label template can be found on the Ashly website for printing input or output channel names under control of the WR-1 and sliding the paper behind the mylar overlay windows. - Page 20 Are Wired To Ch. 1 Gnd/+5 On WR-1 PCB.

LEDs on the ethernet jack showing activity? If using RS-232, is the RS-232 cable properly installed to the PC? Is the software communications enabled using a 24.24M object instead of ne24.24M? This is necessary so that the older Protea System Software can be launched from within Protea NE Software for use with RS-232 applications. Is the software device set to 24.24M? Check the security level (section 9.3). -
