Miktek CV4

Multi-Pattern Tube Condenser Microphone

The CV4 is Miktek’s flagship condenser. It is a large-diaphragm, multipattern mic built around a NOS Telefunken EF800 tube and AMI’s BT4 output transformer.

The capsule is a K67 derivative, built in China to Miktek’s specifications. It is electrically similar to Neumann’s K67/K870, in that the spacer between the backplates is conductive, and the two backplates share a single output wire.

The diaphragm diameter is 25mm. The twin diaphragms are made of 4-micron Mylar and are center-terminated.

The mics are assembled and tested in Nashville using components from around the world.

The mic ships its power supply, 7-pin XLR cable, both a swivel mount and an elastic shockmount, and wooden presentation case, all packed into an aluminum flightcase.

When the headphones go on, the CV4 will impress, simply because whatever instrument it’s on, sounds so good. My first test — using a Groove Tubes Vipre … with an old, jumbo Guild 12-string — sold me immediately. Without trying to sound cliché, the top was crisp without being brittle, the mids were strong and present and the bottom huge, but not loose.

On voice… [i]t sounded neutral and accurate, but with a bit of flattering magic added behind the scenes… and there was certainly no tradeoff in smoothness or detail. The sense of detail also shone through in the tests on acoustic guitar and hand percussion, where the mic responded well to the instruments’ lively sound.
