⚡ At a Glance
- • Sound Signature: Precise mids, controlled bass, clear highs
- • Best for: Home gamers, PS5 and PC users, and owners of active desktop speakers
- • Not ideal for: Users who need Bluetooth wireless connectivity
Balanced, controlled bass with clear highs for both games and music. Master volume and bass/treble controls allow quick tonal adjustments on a compact desktop unit.
Immersive gaming audio - with USB Type C, optical and coaxial inputs
USB Type C accepts digital audio and can act alongside the included USB-A/C cable, while optical and coaxial inputs support higher sampling rates. The unit converts those digital inputs to analogue RCA and 3.5 mm outputs for headphones or powered speakers.
Clean stereo output to active speakers or headphones gives a more convincing soundstage for PS5 and PC gaming, equivalent to using an external sound card.
Plenty of headphone power - with rated output across impedances
Rated output power is 1000 mW at 16 Ω, 500 mW at 32 Ω, 300 mW at 64 Ω, 150 mW at 128 Ω and 80 mW at 300 Ω, and the circuit can drive headphones from 16 Ω up to 300 Ω.
Ample headroom for both low-impedance in-ear monitors and higher-impedance over-ear headphones, delivering louder, cleaner dynamics without obvious strain.
Low-noise, tunable playback - with NE5532 op-amp and tone controls
Design centres on a Texas Instruments NE5532 op-amp, with circuit optimisation for a low noise floor; THD is specified at ≤0.003% and SNR at ≥110 dB. Master volume, bass and treble controls plus an input mode switch provide on-desk tonal adjustments.
Quiet background and defined transient response make subtle details easier to hear, while simple tone controls let users adapt sound to headphones and room acoustics.
