The Z&H Designs HO2 All Discrete 2-Channel Mic Preamp is a high-performance analogue preamplifier that combines transparency, versatility, and character in a compact two-channel format. Matching its 8-channel counterpart, the HO8, the Z&H Designs HO2 is built with an all-discrete circuit design featuring six independent high-voltage opamps and powered by a robust 56V linear power supply. These specifications provide up to 75dB of microphone gain while maintaining linear frequency response, stable headroom, and precise distortion behaviour.
With its ultra-sophisticated analogue circuits, the Z&H Designs HO2 delivers a vivid and natural sound that is equally suited to vocals, acoustic guitar, piano, and strings. On its clean side, it preserves clarity and realism even at high gain levels. On its coloured side, the Z&H Designs HO2 extends beyond neutrality with its unique sonic options, including an additional permalloy output transformer that introduces tasteful harmonics and extra tonal depth when engaged. This makes the Z&H Designs HO2 capable of both faithful reproduction and creatively driven colouration, outperforming far more expensive boutique preamps in specific applications.
Each channel is equipped with a stepped gain knob in 5dB increments, linear trim-matching in 10dB intervals, a DI input switch for direct recording of guitars, basses, and other electric instruments, and comprehensive utilities including phantom power, pad, polarity invert, and a 3-level low cut filter. These features ensure the Z&H Designs HO2 is a reliable and flexible choice for everything from solo vocal sessions to orchestral and band recordings.
With a curved anodised front panel, neon dB meters, and solid stepped controls, the Z&H Designs HO2 is built to the highest boutique-grade standards. Every unit is handcrafted and tested by mixing engineers before shipping, guaranteeing consistency and performance. Backed by worldwide free shipping, a 14-day trial guarantee, and a five-year warranty, the Z&H Designs HO2 is a premium yet versatile mic preamp for studios of any size.
