Critic Reviews

Speck X Sum

soundonsound.com

The Speck X.Sum is a high-quality summing amplifier praised for its transparent sound, flexibility, and impressive technical specifications. Its ability to handle up to 32 inputs and daisy-chain for even more channels makes it a versatile choice for professional setups. The unit provides adjustable gain and panning, though some may find the lack of center detents on pan controls and the fiddly monitor Mix-B button slightly frustrating. Optional breakout boxes are needed for certain I/O tasks, but the overall build quality and sound performance are commendable, making it a strong contender for those seeking a clean, powerful mix without added color.
