ASHLY NE24.24M 20X4 Protea DSP Audio Matrix Processor 20-In x 4-Out

Product Overview

The Ashly NE24.24M 20X4 is a Protea DSP audio matrix processor configured with 20 inputs and 4 outputs, built on the modular NE24.24M platform that uses field-installable expansion cards to reach the 20x4 configuration from the 4x4 base unit. Designed for commercial AV installations requiring many audio sources distributed to a smaller number of output zones, the 20x4 configuration suits applications such as broadcast routing, large conference facility source distribution, and multi-source AV systems with consolidated output zones. The Protea DSP engine on each expansion card delivers equalization, dynamics, crossover filtering, delay, automatic feedback suppression, and matrix routing, with control via 10/100 Ethernet and RS-232 and compatibility with third-party room control systems including Crestron and AMX.

Product Description

The NE24.24M 20X4 uses the same NE24.24M chassis as other configurations in the series, with expansion cards installed to achieve 20 analog inputs and 4 analog outputs. Each expansion card adds 4 channels of DSP processing with its own dedicated DSP processor, providing substantial processing power across all 20 input channels. Any of the 20 inputs can be routed to any of the 4 outputs with individual level control at each routing point, making the 20x4 configuration well suited for facilities with many audio sources feeding a smaller number of amplified zones or output devices. The Protea DSP library on each channel includes variable-Q graphic and parametric equalization, high-order crossover filtering, advanced automatic feedback suppression, autolevelers, compressors, matrix duckers, limiters, frequency-keyed noise gates, and delay up to 1365ms per channel for time alignment. Euroblock connectors on all audio I/O provide secure and compact rack-mount connections. DC remote level control and preset recall inputs support wall remote and room control system integration. An optional GPO logic card can trigger projection screens, curtains, and lighting. With 31 preset locations, multi-level software security, and Ashly Remote iOS app support, the NE24.24M 20X4 fits commercial AV systems of varied complexity.

Frequently Asked Questions

Why would I choose the 20X4 configuration over the 12X12?

The 20X4 is better suited for installations where many audio sources need to be selected and mixed down to a small number of output zones. The 12X12 provides equal input and output counts for more symmetric multi-zone distribution. The choice depends on the specific source-to-zone ratio the installation requires.

Is the NE24.24M 20X4 an amplifier?

No. The NE24.24M is a DSP audio matrix processor only. External power amplifiers are required to drive loudspeakers from the processor's outputs.

Can expansion cards be added to the NE24.24M 20X4?

Yes. The chassis accommodates additional expansion cards up to the 24-channel maximum, and existing cards can be replaced or reconfigured without reprogramming the device.

What control protocols does the NE24.24M 20X4 support?

The unit supports 10/100 Ethernet and RS-232, with compatibility for Crestron, AMX, and other third-party room control systems.

How many presets does the NE24.24M 20X4 store?

The unit stores 31 preset locations, each of which can contain a complete system configuration for different room setups or operational modes.
