$640. Cool little mono tube compressor; 12AX7 and a Vactrol. The manual says it all: The Hx Series from Demeter Amplification is a revolutionary approach in tube design utilizing innovative tube circuitry for the amplification functions and the latest in solid state for the driver functions. All Hx Series equipment use the finest quality components featuring metal film resistors, high quality film capacitors, and custom toroidal power transformers housed an attractive aluminum and steel single space rack mount case. All units feature fully regulated power supplys supplying 200V to the tubes and + and - 18V for the solid state components, giving all Hx series components tremendous headroom up to + 28 dB output into 600 ohms. More pics below. Here's the spec from the website:
Clean, Classic Compression
Now you can have the sound of a classic tube optical compressor without the noise and low fidelity sound often associated with them. In a compact and versatile package, the HXC-1 HX Series Compressor sets a new standard for sonic quality in tube compressors. The HXC-1 is a mono tube compressor utilizing the revolutionary H tube preamplifier with a classic photo cell compressor section. The unit has a variable attack (.5 to 100 millisecond) and release (100 millisecond to 3 seconds), input sensitivity switch, overload LED, compression control (over 24dB), change and VU meters, side chain outputs, link inputs, low frequency compression sensitivity switch and output gain control.
