Manley Laboratories

Manley Laboratories makes valve audio equipment in the US. Its studio-oriented processing also appears in an elaborate listening-bar signal chain.

Design & approach

Manley manufactures professional valve microphones, preamplifiers, equalizers and compressors. Its Massive Passive film explains the development of a particular equalizer rather than making a general claim about valve sound. In a listening venue, that unit belongs to the signal-shaping stage and should be distinguished from amplification that drives the loudspeakers.

Inside the system

The Main Room combines OJAS × NNNN ON2 and NNNN Gage 125 loudspeakers with McIntosh C55 control electronics, Powersoft Unica amplification and Rupert Neve Designs and Manley processing. The signal-processing equipment includes Neve MBT, P2MB and RMP-D8 units and a Manley Massive Passive stereo valve equalizer. The booth offers ARS 9900BW, 5000 and 3500LE equipment alongside an AlphaTheta euphonia mixer, Technics SL-1200G-S decks and Pioneer CDJ-3000 players. An Isonoe five-band equalizer, Benchmark DAC3 HGC and NNNN monitoring broaden its control and playback options. The Blue Room follows a separate OJAS chain: TAD loudspeakers, a Super-sub, Phonoplayer 1200G, April phono stage and April PSET 300B amplification. The contrast between the extensively processed Main Room and the dedicated valve-amplified Blue Room is a defining feature of the installation.
