Description
Key Features
- 25 watts per channel into 8Ω from a compact cast aluminium half-width chassis — a figure that understates the amplifier’s real-world drive capability, owing to its well-engineered power supply
- Diecast non-ferrous alloy outer case and diecast aluminium chassis with integral heatsink — an unusually rigid construction that actively contributes to sonic performance by suppressing resonance and microphony
- Built-in MM/MC phono stage — accepts both Moving Magnet and Moving Coil cartridges, with separate sensitivity settings for each. The MC capability was uncommon at this price point in the mid-1980s
- Five inputs: Tape, Video, AUX, CD, and Phono — with the ability to listen to one source while recording another
- Separate Listen and Record selector switches for flexible tape monitoring
- Balance control offering ±5dB adjustment per channel, designed for room correction rather than channel isolation
- Headphone output on the front panel
- Minimalist signal path philosophy — only essential circuit stages are included, with selected passive components and ALPS switches throughout
- Made in England by Cyrus Electronics
