ASHLY FX60.4 1/2-Rack Compact 4-Chan Power Amp with DSP, 4 x 60W at 4/8 Ohms

Product Overview

The Ashly FX60.4 is a four-channel Class D power amplifier with integrated Protea DSP, delivering 60W per channel at 4 or 8 ohms in a half-rack chassis with built-in Wi-Fi and Ethernet connectivity. The 4-input by 4-output DSP engine provides complete signal processing across four independent zones, making the FX60.4 a true single-box four-zone amplification and processing solution for background music, distributed audio, and paging systems in commercial spaces where compact form factor is required. Dynamic Power Sharing can concentrate available power to a single channel when needed, and each channel pair can be bridged at 70V or 100V for constant-voltage distributed speaker operation.

Product Description

The FX60.4 delivers 60W to each of four independent channels from a half-rack chassis smaller than any conventional 4-channel installation amplifier. Advanced Dynamic Power Sharing allows the full available power budget to concentrate on a single channel pair when others are unloaded, or to distribute asymmetrically between channels to accommodate mismatched speaker loads. Two channel pairs can each be bridged for 70V or 100V constant-voltage operation, allowing mixed low-impedance and distributed speaker zone configurations in the same chassis with no external bridge adapters. Total available power including dynamic sharing can reach 250W on a single channel when all other channels are unloaded.

The Protea DSP engine processes four inputs through four independent outputs. Input processing handles gain and sensitivity for each of the four inputs. Zone processing includes source selection, mono/stereo switching, compressor, and level metering. Output processing provides up to 100ms of delay per output, 10-band fully parametric EQ, crossover, polarity selection, and a three-mode limiter (clip, peak, RMS). Speaker presets can be created, saved, and loaded independently per output channel, supporting different speaker models on each zone in the same system. FIR filter import is supported for manufacturer-optimized speaker tuning files.

The browser-based interface requires no software installation and is accessible from any PC, tablet, or smartphone on any OS through the built-in Wi-Fi access point or Ethernet connection. Addressable GPIO, per-channel assignable VC remote ports, and standby/mute ports integrate with wall remotes, control processors, and building automation systems. SPDIF digital I/O enables digital source connectivity and system expansion through digital bridging to additional FX units. 5-year Ashly limited warranty included.

Frequently Asked Questions

How does the FX60.4 differ from the FX60.2?

The FX60.4 has four amplifier output channels and a 4-input x 4-output DSP configuration, while the FX60.2 has two channels and a 4-input x 2-output DSP. The FX60.4 is suited for four-zone systems; the FX60.2 serves two-zone applications. Both share the same half-rack chassis dimensions and feature set.

Can the FX60.4 operate two separate 70V zones simultaneously?

Yes. Each of the two channel pairs (channels 1-2 and channels 3-4) can be independently bridged to operate at 70V or 100V, providing two separate constant-voltage zones from one FX60.4 chassis.

How does Dynamic Power Sharing work on the FX60.4?

Advanced Dynamic Power Sharing automatically monitors all channel loads and redistributes available power between channels within each pair. If one or more channels are idle or lightly loaded, their unused power shifts to the remaining active channels, with up to 250W available on a single channel when all others are unloaded.

Does the FX60.4 include full speaker processing on all four outputs?

Yes. Every output channel includes 10-band parametric EQ, crossover, delay, polarity, FIR filter support, and three-mode limiter. Speaker presets can be created and loaded independently per output for systems with different speaker models on different zones.

What mounting accessories are available for the FX60.4?

Ashly FA1.2RM (rack-mount kit), FA2.2RM (rear rail support), and FATWB (flush wall/surface-mount bracket) are available as optional accessories for standard 19-inch rack or surface-mount installation.
