ASHLY ne24.24M [4/28] Introduction

Operating Manual - ne24.24M Matrix Processor

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. The base unit offers a four-input/four-output conguration. Each input and output expansion card has individual

DSP processing allowing expansion of the base unit’s total inputs or outputs four channels at a time. In addition, an eight chan-

nel general purpose logic control output expansion card is available for controlling lighting or AV equipment through the Protea

NE Software, or by recalling presets.

Expansion cards - Inputs, outputs, or a logic output card are easily installed in the eld without the need to reset

switches or reprogram the device.

Input channel processing blocks include: Mic Preamp with up to 60dB Gain, 48V Phantom Power and “Push to Talk”

switching, Input Level with Polarity, Passive potentiometer or active RD-8C Remote Level Control, Time Delay, Fifteen Band

Fully Parametric EQ, Noise Gate, Autoleveler, and Ducker.

Output channel processing blocks consist of a Cross Point Mixer, HPF/LPF, Delay, fteen EQ Filters, Gain, Remote

Level Control, and Limiter. The cross point mixer in the output section allows you to route any input to any output at any level

and mute any input at any output without affecting the input conguration. The HPF/LPF crossover section offers Bessel, But-

terworth and Linkwitz-Riley lters with 12, 18, 24 and 48dB octave slopes.

Matrixing allows you to route any input to any output and control individual levels once they have been assigned.

Fixed path architecture and extensive processing power per channel will reduce the amount of time it takes to set up the system.

Programming requires Ashly’s Protea NE Software on a Windows PC using a standard 10/100BASE-T ethernet con-

nection. Note: Protea NE Software will not work over RS-232, that is used for non-ethernet systems only.

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.

2. UNPACKING

As a part of our system of quality control, every Ashly product is carefully inspected before leaving the factory to

ensure awless appearance. After unpacking, please inspect for any physical damage. Save the shipping carton and all packing

materials , as they were carefully designed to reduce to minimum the possibility of transportation damage should the unit again

require packing and shipping. In the event that damage has occurred, immediately notify your dealer so that a written claim to

cover the damages can be initiated. The right to any claim against a public carrier can be forfeited if the carrier is not notied

promptly and if the shipping carton and packing materials are not available for inspection by the carrier. Save all packing ma-

terials until the claim has been settled.

3. AC POWER REQUIREMENTS

Note: The AC power switch for model ne24.24M is on the back panel. The Protea ne24.24M uses a universal input

power supply which will accept any line voltage from 90VAC to 240VAC, 50-60Hz. A standard IEC-320 grounded AC inlet

is provided on the rear panel to accept the detachable power cord. Never remove the AC earth ground connection to the

ne24.24M. In the event of fuse failure, refer the product to a qualied service technician for fuse replacement, replacing only

with the same type and rating fuse.

WARNING: THIS APPARATUS MUST BE EARTH GROUNDED
