CM47LE

THE CM47LE IS A FULL BODY OR LONG BODY VERSION OF THE ORIGINAL U47 CIRCA 1959.

THE CAPSULE, TUBE, TRANSFORMER AND CIRCUITRY ARE BASED ON THE TRADITIONAL SPECIFICATIONS OF A 1959 U47

THE 1959 U47 WAS FITTED WITH THE VENERABLE VF14M TUBE &

K47 CAPSULE WITH A BRASS SURROUND

WITH THE CM47LE YOU GET THE OPTION OF MODERN MULTI-PATTERNS WHILE RETAINING THE TRADITIONAL, PASSIVE-CARDIOD RESPONSE OF THE U47 WITH THE FLIP OF A SWITCH!!

THIS IS ACCOMPLISHED WITH A SWITCH ON THE BODY LABELLED:

In Passive-Cardiod there is 3db more output from the capsule and the self-noise is reduced by 3db compared to active cardiod.

In the "M" switch position, the 9 pattern switch is engaged; Active CARD is in the centre and OMNI is full counter clock-wise while FIG 8 is in the full clock-wise position from the 9 pattern switch located on the power supply.

The CM47LE features a traditional single stage class "A" transformer coupled U47/U48 tube circuit.

The military grade 7 pin sub-miniature tube is simple to replace.

Also, the clever lads at Advanced Audio added a passive cardiod/multi-pattern option.  This allows for 3 patterns between OMNI and Cardiod and 3 patterns between Cardiod and FIG 8.  The traditional passive, cardiod method used in the original U47 is retained in the C position on the CM47LE

Project studios can have a true classic sounding tube microphone for a very affordable price.  Tested replacement tubes will be $21

The CM47LE is also designed to work seamlessly in any serious commercial recording studio and with a variety of microphone preamps

Like the original circuit designs, we are using a 7-pin military grade pentode tube wired as a triode like the U47 and mounted in a ceramic tube socket.
