A High‑Performance, GaN‑Driven Engineered Solution for Active Loudspeakers
The Orchard Audio 1200W Plate Amplifier is a purpose‑built platform for modern active loudspeaker designs. Engineered around a robust 1200W power supply and your choice of GaN‑based Starkrimson Ultra and GaNM-based Starkrimson 25 modules, it delivers exceptional clarity, dynamic headroom, and system‑level flexibility for both OEMs and advanced DIY builders

At the core is a high‑efficiency 1200W supply feeding up to four discrete amplifier channels. The plate can be configured in multiple ways—4‑channel, 3‑channel, or 2‑channel—allowing designers to tailor output power and topology to the loudspeaker’s drivers.

Amplifier Module Options

• 1 or 2 × Starkrimson Ultra Modules
  • 250W / 500W into 8Ω / 4Ω
  • GaN‑based architecture for ultra‑low distortion and exceptional transient accuracy
  • Ideal for bass and mid-range drivers
  • Specifications for Starkrimson Ultra Modules are at this link
• 1 or 2 × Starkrimson 25 Modules
  • 75W / 150W into 8Ω / 4Ω
  • GaNM‑based architecture for ultra‑low distortion, wide bandwidth, and exceptional transient accuracy
  • Ideal for tweeters, midrange drivers

Modules can be mixed or doubled, enabling 2, 3, and 4 channels of amplification.

Integrated DSP for Complete System Control

The platform incorporates the Hypex DSP3‑224 for advanced crossover design, EQ, phase alignment, and driver correction. Paired with the Hypex DIGin3‑322, the system supports high‑quality digital inputs for seamless integration into modern audio ecosystems

Designed for Active Loudspeakers

Every aspect of the plate amplifier—from thermal layout to module selection to DSP integration—has been optimized for active loudspeaker builders who demand accuracy, reliability, and configurability. Whether powering a 2‑way monitor or a high‑output 3/4‑way tower, this amplifier provides the foundation for a truly reference‑grade active system.

Hypex DSP3-224 and DIGin-332

Filter design and system configuration are handled via Hypex Filter Design (HFD) software, with support for IIR and FIR filters. Output routing allows flexible assignment, including BTL operation when connected to compatible two-channel amplifiers.
