    Connectors are euroblock for all audio inputs and outputs, eight Logic Inputs for preset recall, eight channels of remote DC level control, and a data connection for Ashly’s WR-5 active remote . Ethernet uses an RJ45 connector, while RS-232 uses a Dsub 9 female .

    4 .4 Main Input Channel LEDs The ne24.24M base unit has four fixed input channels. Each input channel’s two color Sig LED indicates input signal level of -20dB (green), or +20dB clip (red) respectively . The Sig LEDs detect signal levels after any gain adjustments are made within the ne24 .24M preamp section .

    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 .

    6 . EXPANSION MODULE INSTALLATION The Ashly ne24 .24M can be ordered from the factory with expansion modules pre-installed to suit the application, or as a 4 x 4 base unit . Should the need arise to add input or output capacity at a later time, as well as logic output function, ad- ditional modules can be purchased and easily installed in the field.

    Ashly Protea software is included on a CD with each unit . Check the Ashly web site at www .ashly .com to verify that you are installing the latest software release . Autorun will launch the application<ProteaSystemSoftwareNE> to install the Protea software.

    Operating Manual - ne24.24M Matrix Processor 8 . AUDIO FUNCTIONS 8 .1 Input Functions Editing of audio controls is done primarily in Protea System Software . Input and output expansion cards are autode- tected, and the software automatically updates to display the current ne24 .24M status . Note: Accidental, potentially destructive loudspeaker damage can occur when abrupt changes are made to EQ, filter, or level controls, so plan carefully before making radical changes to a live sound system .
  • Page 11 Operating Manual - ne24.24M Matrix Processor be crystal clear sound directly in front of any one loudspeaker can be unintelligible at the farther reaches of the venue with direct line-of-sound to multiple loudspeaker sources . The solution is to delay the audio signal to the loudspeakers located further away from the primary source, so that sound comes out of the distant loudspeakers at the exact time that sound from the main loudspeakers arrives .
  • Page 12 Operating Manual - ne24.24M Matrix Processor Protea ne24.24M parametric filters have a boost/cut range of +15dB to -30dB. There is more cut than boost because one of the more common uses for parametric filters is to dramatically cut, or “notch out”, very narrow frequencies (low bandwidth) in order to eliminate system feedback problems.
  • Page 13 Each input channel can be remotely attenuated through the back panel 0-5V Remote Level Control pins in conjunction with the Ashly WR-1, WR-1 .5, or by an Ashly RD-8C 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...

    Operating Manual - ne24.24M Matrix Processor Output Functions 8 .2 Output Audio Functions The following functions are available on all outputs: Mixer, High Pass/Low Pass Filter, Delay, EQ, Gain, Limiter, and Mute . 8 .2a Output Matrix Mixer (Input Mixer) Output channels can have any or all inputs as sources, and the output matrix mixer allows the level of each connected input to be adjusted in the “matrix mix”...
  • Page 15 The steeper the slope, the more abruptly the “edges” of the pass band will drop off. There is no best filter slope for every application, so experiment to see which one sounds most pleasing in a specific system. The Ashly default crossover fil- ter is 24dB/octave Linkwitz-Riley, but of course they can be changed to suit the application .

    <preset options>, then <Save Sub Preset> . 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.

  • Page 18: Metering

    Separate software tabs allow for input/output metering in dBu, as well as dynamics metering in dB . 10 REMOTE CONTROL Ashly makes several remote control options which can be used with the ne24 .24M . The WR-1, WR-1 .5, and WR-2 are passive wall-box mounted remotes which can adjust volume or select presets .

    WR-2 remote level control ground to any other external grounds . The terminal numbers 1-8 correspond to the first 8 Preset Memory locations in the ne24.24M. Pressing a button will load the corresponding preset . A label template can be found on the Ashly website for printing preset names for the WR-2 and sliding the paper behind the mylar overlay windows .

    .24M . Up to four WR-5 units can be daisy-chained and phantom powered from one ne24 .24M, and even more can be added using an in-line power supply adapter such as the Ashly RPS-18 . Note: If a WR-5 is used, no other serial communica- tions devices, including the Ashly RD-8C, may be used with the ne24 .24M .

    .24M . Connecting and powering the neWR-5 is done using Cat-5 Ethernet cable and an IEEE 802 .3af Power over Ethernet (PoE) switch, hub, or in-line PoE injector . If PoE is unavailable, the Ashly RPS-18 (sold separately) is a 15-48VDC power supply capable of at least 2 watts per neWR-5 and can be hard wired to the back of the neWR-5 .

    1) No power - Is the detachable AC cord fully plugged in? Is the rear panel power switch on? 2) Software doesn’t work on unit - Is the ethernet connection properly made? Has the ne24.24M been identified by the software? Are the LEDs on theRJ-45 ethernet jack showing activity? 3) No sound - Check to see if the input or output is muted in software or by a remote control action .
