Manley Labs CORE Tube Reference Channel Strip
EAN: 890833001851
The CORE Tube Reference Channel Strip from Manley Labs is a single-channel signal processor with an intuitive front panel layout that allows for quick and easy adjustment over mic preamp, compressor, EQ, and limiter settings. The CORE incorporates many of Manley s technological innovations including the preamp from the VOXBOX, featuring a hand-wound iron transformer with nickel laminations, negative feedback gain circuit, and triode vacuum tube circuit. The direct input offers an all discrete solid-state path with a 10 Ma„¦ impedance.

The direct input offers an all discrete solid-state path with a 10 Ma„¦ impedance.
The ELOP compressor, also borrowed from the VOXBOX, is an electro-optical (LA-2Astyle) limiter with a set ratio of 3:1. While other manufacturer s designs have the compressor post mic pre, the Core places the circuit before the mic preamp making it near impossible to clip. This also shortens the signal path and ensures a quality, low noise signal.
The unit also features a Baxandall shelf EQs with a sweepable mid frequency and a fast FET brickwall limiter. The large VU meters offer a 3-way toggle switch for monitoring the compressor output, gain reduction and main output. Handmade in the USA, the unit is housed in 2U steel chassis with a CNC machined 1/4 faceplate and inlaid with laser engraved inserts. The CORE ships with an IEC power cable.
