STC4032-D Outside Broadcast Microphone Ex BBC Circa 1955

From the earliest days of outside broadcasting and recording, keeping the microphone dry has always been something of a challenge. Condenser microphones in particular don’t function well in damp conditions, and pretty much any mic can be completely ruined by a good soaking.

These days’ companies such as Rycote make windshields and water resistant protection to cover a wide range of different professional microphones. Back in 1955 STC came up with their own neat and convenient solution to the problem.

Advertised rather grandly as being ‘an all weather instrument’ with ‘full marine and tropical protection,’ the STC4032 is a robust hand-held, omnidirectional, dynamic microphone with a moisture resistant black Bakelite body. The grill is a dual layer of fine stainless steel mesh and an optional windshield (pictured above) may be added to give an additional 15db noise free performance in high winds and additional protection from the rain. The handle incorporates a switch, which can be wired to provide muting or remote start/stop function for a tape recorder (such as the E.M.I Midget).

This super lightweight setup was used by BBC outside broadcasters from 1955 until the mid-60’s and weighed a mere 14lbs!  You may laugh…….. But this was a vast improvement on carting round the previous equipment…….. a BBC Type C portable disc recorder weighing 44lbs!!!   (see pic below)   Perfect for recording in a gondola!                                                                                                     BBC OB Disc cutter Venice 1946Michael Reynolds reporting for the BBC in Venice 1946.

Can’t imagine the rocking of the boat helped the disc cutter very much. The mic is an STC4017c and none of this gear is waterproof (apart from Michael’s sturdy military raincoat!)

The following is a hilarious period piece, almost like something out of Monty Python:

Although it looks somewhat like a World War 2 battlefield telephone, in terms of technical performance the STC4032 is exactly the same as the STC4035 studio microphone, and very similar to the famous Apple & Biscuit STC4021. It has a notably smooth frequency response from 30Hz to around 10 kHz, with a presence peak of around 5db at 6.5kHz . The only difference with the 4032 is the water resistant case.

In Conclusion.

Although ostensibly designed for outside broadcasting, the STC4032 is a high quality dynamic microphone that could be used for many different tasks.

The STC4001B Acoustic Baffle for the STC4021 (Apple & Biscuit) circa 1935.

The very first post that I wrote for this blog back in 2012 was about the STC4021 (Apple & Biscuit). Still one of my favourite microphones.  I even made a YouTube video to go with it! In the course of the video I mentioned the STC4001B Acoustic Baffle. According to the STC brochure this could be purchased to modify the frequency response and directionality of the microphone. These days the 4001B Acoustic Baffle is very hard to find. So imagine my surprise when a brand new old stock 4001B (still in the box) appeared on eBay. 

So I thought I had better ‘Buy it now‘ and make another video to celebrate the occasion!

 

Mélodium  Mélodynamic 75A (1948-1958)

Melodium 75A

Made in Paris between 1948 and 1958 by Mélodium Société, 296 rue Lecourbe 15eme.

Although visually the design harks back to the 1930s it has a surprisingly modern sound. This is borne out by the frequency graph, which shows a smooth response from 50 Hz to 10 kHz.There is a presence lift of 5db at around 4.8 kHz which lends clarity and crispness, particularly to speech and vocals.

The 75A boasts a very light duralumin diaphragm and voice coil (30mg), giving good transient response. It is also claimed that the microphone is impervious to wind, making it an excellent choice for outside broadcasting and sports reporting.

The grill design featured in the technical leaflet above was used on the earlier models.

If you buy a Mélodium 75A it is worth noting that it has very low impedance (10 ohms) and will require the services of an appropriate preamp.

Also, the plug socket on the 75A is peculiar to Mélodium!  (N.B. The earliest models have 3 screw terminals.)

These Mélodium locking plugs are very hard to find!  (They also fit the 42B ribbon mic.)

Famous Users.

The Mélodium 75A was employed extensively by French broadcasters and was used by many famous entertainers and politicians, including the singer Edith Piaf and President Charles de Gaulle.
