We
Engineer the Hardware Inside Professional Audio &
Video.
Analog circuit design, DSP firmware, Dante and AES67 networked audio, broadcast electronics, and macOS/iOS control software — full-stack professional AV hardware engineering under one roof.
The Challenge
Professional AV Hardware Engineering Demands Technical Depth That Most Firms Don't Have.
Professional audio hardware is one of the most technically demanding product categories to engineer. The analog performance of a preamp stage — noise floor, CMRR, THD+N — is determined at the schematic level and cannot be fixed in firmware. The latency of a DSP chain is determined by firmware architecture decisions made in the first week of development. A USB Audio Class 2 implementation that introduces 50 samples of jitter will be noticed within minutes by any engineer who sits down to track with it.
The AV over IP transition — Dante, AES67, NDI, SMPTE 2110 — has added a full networking layer on top of already complex hardware and firmware requirements. Every professional AV manufacturer now needs to build hardware that speaks these protocols natively, at the firmware level. That requires engineers who understand both the analog signal chain and the IP network stack — simultaneously, without handing one off to a subcontractor.
Ankh Innovations works at this intersection. We design preamp circuits, write DSP firmware, implement Dante and AES67 endpoints, build the macOS and iOS control applications, and certify the final hardware — one team, one product, no interface gaps between the analog and digital disciplines.
Professional AV Hardware We Engineer
Eight product categories spanning the complete professional audio and video hardware landscape — from analog preamp to IP-networked AV endpoint.
Analog & Mixed-Signal Design
Electronics Design →Discrete and IC-based preamp circuits, AD/DA converter topology selection, phantom power distribution, balanced line drivers and receivers, headphone amplifier stages, power supply design for low-noise audio applications, and EMI management for AV hardware operating in RF-dense environments.
Audio DSP & Firmware
Audio Engineering →Real-time DSP firmware on ARM Cortex-M, SHARC, and FPGA platforms — biquad parametric EQ, FIR/IIR crossover filters, dynamics processing, acoustic echo cancellation, sample rate conversion, and convolution reverb. DMA-based zero-copy audio pipelines targeting sub-millisecond end-to-end latency.
Networked Audio & Video Protocols
Protocol Integration →Dante endpoint firmware development with Audinate chipset integration, AES67 clock synchronization via IEEE 1588 PTP, AES/EBU and AES3 digital audio interfaces, USB Audio Class 2 driverless operation, NDI hardware encoding and decoding, and SMPTE 2110 video-over-IP endpoint development.
Control Software & Applications
Software Development →Native macOS and iOS control applications in Swift — mixing surface control, DSP parameter editors, wireless system managers, and OTA firmware update tools. Web-based device configuration interfaces for browser-accessible control of networked AV hardware.
Broadcast & Video Electronics
Broadcast Electronics →Custom SDI and HDMI capture and processing electronics, broadcast tally systems, PTZ camera control electronics, SMPTE timecode generation and distribution hardware, broadcast console I/O modules, frame synchronization hardware, and AV over IP endpoint development for Dante, NDI, and SMPTE 2110.
Certification & Standards Compliance
Certification Support →FCC and CE certification for professional AV hardware, Dante certification pathway via Audinate, USB Audio Class 2 compliance validation, Bluetooth SIG certification for wireless audio, and EBU R68 and EBU R128 loudness standard compliance for broadcast hardware.

Platforms We Build Professional AV Hardware On
Why Engineering Teams Choose Ankh
Analog-to-App Under One Roof
Preamp circuit design, AD/DA selection, DSP firmware, USB audio driver, and macOS control application — all engineered by the same team with no interface gaps between disciplines. When the noise floor of your preamp stage and the latency of your USB driver are both your problem, you need one partner who owns both.
Latency Is Not a Compromise
Professional audio lives and dies on latency. Our firmware architecture treats sub-millisecond audio pipelines as a hard constraint, not a feature to be optimized later — designed in from the first line of code through DMA buffer sizing, interrupt priority allocation, and zero-copy audio path architecture.
Protocol Fluent
Dante, AES67, AES/EBU, USB UAC2, NDI, SMPTE 2110 — we implement networked audio and video protocols at the firmware level, using Audinate chipsets for Dante, IEEE 1588 PTP for AES67 clock synchronization, and custom endpoint firmware for NDI and SMPTE 2110. Not off-the-shelf modules. Real firmware.
Certification Without the Rework
FCC, CE, USB-IF, Dante certification, Bluetooth SIG — we design to certify from day one. EMI layout guidelines are followed from the first PCB revision, not retrofitted after a pre-compliance test failure. Your first formal submission should be a confirmation, not the start of a redesign cycle.
Custom Dante-Networked Stage Monitor System
Custom Class D amplifier board, Dante-networked audio input with Audinate Brooklyn II integration, DSP processing firmware with 12-band parametric EQ and protection limiting on ARM Cortex-M7, and iOS control app — from schematic to CE and FCC certification in 28 weeks for a professional loudspeaker manufacturer.
