Product Overview
At YZ AUDIO, we offer the Digital Audio Matrix Processor With 16 analog inputs and 16 analog outputs for commercial audio projects that need flexible signal routing and repeatable tuning. Built around the ADI SHARC 21489 processing platform, this unit combines matrix mixing, acoustic echo cancellation, feedback suppression, noise suppression, and parametric equalization in one rack-mounted chassis. The purpose is not to increase loudspeaker power: it is to prepare, distribute, and manage audio signals before they reach external power amplifiers, active loudspeakers, or conferencing endpoints.
For conference integrators, the processor with 48 kHz/24-bit conversion helps manage multiple microphones, playback sources, and output zones without rewiring the system every time a room layout changes. A built-in USB sound-card function is described for playback, recording, and software meetings. Engineers can use the published 16×16 I/O count to plan signal paths, while checking the exact routing, USB channel mapping, and control configuration against the supplied software before tender submission. Our team can discuss project topology, control integration, and production options based on your system diagram.

Key Features
- 16×16 analog matrix routing: Sixteen analog inputs and sixteen analog outputs give designers the physical I/O capacity to distribute microphone and program feeds across multiple destinations; confirm the precise mixing and routing matrix in the control software.
- ADI SHARC processing engine: The listed SHARC 21489 runs at 450 MHz with a published processing capability of 400 MIPS and 1.6 GFLOPS, providing a hardware platform for real-time DSP functions.
- 48 kHz/24-bit signal processing: The stated sampling and quantization format supports modern conferencing and installed-audio workflows; a 40-bit floating-point DSP engine is separately listed.
- AEC for hybrid meetings: The product page describes bus-type acoustic echo cancellation with a 512 ms tail and a published 60 dB/s convergence rate; real-world results depend on room acoustics and routing.
- Feedback and noise management: Independent-channel AFC uses notch filtering, while ANS targets background noise; the published 10 dB gain and 18 dB SNR improvement figures are vendor-stated, not guaranteed site outcomes.
- Eight-band parametric EQ: Five filter types-parametric, low shelf, high shelf, low pass, and high pass-help tune speech clarity and loudspeaker response without additional outboard equalizers.
- Control and interface options: One RS232 channel and a configurable end-user interface are listed; the manufacturer describes managing up to 30 devices from one interface, subject to software compatibility.
- USB conference connectivity: A USB audio interface is described for playback, recording, and software conferencing; verify operating-system support and the actual number of USB audio channels.

Customization & OEM/ODM Services
We can review OEM/ODM requests for the Digital Audio Matrix Processor With based on the required channel map, acoustic algorithms, control environment, and purchase volume. Typical requests include front-panel branding, enclosure finish, labeling, shipping carton artwork, software interface layout, and preset configuration. More extensive changes-such as alternative analog channel counts, a different control protocol, or additional DSP algorithms-require a separate engineering feasibility assessment rather than a promise that the existing 16×16 hardware can be modified without redesign.
For system integrators, we recommend supplying a signal-flow drawing, microphone schedule, output-zone list, required AEC channel count, controller make/model, and acceptance-test criteria. We can then discuss an evaluation unit or engineering sample, followed by verification of routing presets, control commands, audio performance, and final labeling. MOQ is 100 units; sample lead time is 7–15 working days after specification approval. Standard dispatch is 15 business days; customized production is 30 working days. These terms are stated in the written quotation. Contact Us with your DSP block diagram for a configuration review.
Why Choose YZ AUDIO
YZ AUDIO focuses on commercial audio and conferencing equipment for integrators who need more than a generic processor listing. For this 16×16 model, the published technical information includes the DSP chip, channel count, processing format, measured audio parameters, AEC/AFC/ANS functions, control interfaces, power requirements, and enclosure dimensions. Those details allow consultants to evaluate fit against a bill of quantities before requesting samples. We recommend validating the proposed configuration through bench tests and a site acceptance checklist, including phantom-power loading, channel isolation, routing recall, echo control, and recovery after power interruption.
For procurement planning, request a quotation that explicitly states available quantity, standard shipment lead time, engineered-order lead time, sample terms, warranty period, spare-part availability, and expected service life under defined operating conditions. Responses are provided within 24 hours. Similarly, CE and RoHS documentation and ISO management-system certificates should be provided only when their scope, validity, and relevance to this exact model have been checked.
The manufacturing base covers approximately 80,000 m², with 6 production lines and an annual capacity of 100,000 units per year. We encourage overseas buyers to request the latest test report, firmware/software version, packing list, and approval sample before bulk purchase. Contact Us to obtain model-specific documentation and an OEM/ODM feasibility assessment.
Application Scenarios
- Corporate boardrooms: Route table microphones, far-end audio, and presentation sources while using AEC to support hybrid meetings. Confirm USB routing and conferencing software interoperability during commissioning.
- Divisible conference centers: Assign the 16 analog inputs and 16 outputs to meeting-room partitions and store separate presets, subject to the software's supported preset and control features.
- Theaters and performance venues: Apply equalization and signal routing to speech and program feeds, with external amplifiers providing loudspeaker power. Validate latency and headroom for each audio path.
- Sports and multipurpose facilities: Distribute announcements and background program sources to separate amplifier channels while using control integration for operational changes.
- Theme parks and attractions: Coordinate multiple audio feeds and external control events; verify synchronization, network architecture, and fail-safe requirements before specifying the processor.
FAQ
Q: What is the MOQ for this processor with 16×16 I/O?
A: MOQ is 100 units; it may differ for standard units, branded units and engineering changes. Send your destination market, volume, and labeling requirements to Request a Quote.

Processing architecture: The SHARC device and stated MIPS/GFLOPS describe available compute resources, not the number of simultaneous algorithms that can run in a particular preset. Ask for a validated DSP configuration if your project requires AEC on many channels at once. The 48 kHz/24-bit format defines sampling and digital resolution; it should not be confused with the separate 40-bit internal floating-point processing engine.
Audio connections and gain: A 16×16 analog I/O layout provides useful routing density for boardrooms and divisible meeting spaces. The site labels the selectable input gain range in dBu, which is a level unit rather than a gain unit; verify whether the intended unit is dB before publishing a wiring or gain-staging guide. +48 V phantom power supports compatible condenser microphones, but the 10 mA maximum and per-channel availability should be checked against microphone requirements.
Measured performance: The specification table states a ±0.3 dB frequency response from 20 Hz to 20 kHz, +18 dBu maximum level, 113 dB input/output dynamic range, and 108 dB channel isolation. These values help designers assess headroom, low-level detail, and channel separation. The feature list elsewhere gives 110 dB dynamic range and 0.002% THD+N at +4 dBu, so test conditions and authoritative values require confirmation. A system delay below 3 ms describes the processor path, not end-to-end conferencing latency.
Power, footprint, and integration: The 482 × 260 × 45 mm chassis suits standard rack planning, while AC 110–240 V, 50/60 Hz simplifies deployment across regions. Confirm actual rack ears, ventilation clearance, network control interfaces, and software versions. RS232 provides an integration route for supported controllers; protocol documentation is necessary before programming automation.
