'His Master's Voice Mobile Recording Van
The recording equipment used by HMV, Columbia and Parlophone was all Western Electric and, in essence, identical. Engineers went to the USA in 1925 to familiarise themselves with it. The microphone used was a condenser (or capacitance microphone) mounted on a wooden box with the essential amplifier inside, protected from vibration as much as possible. This was a superb instrument in spite of its bulk.  

​Some writers have tried to say that the van sent the sound by wire to London. This not so.  All HMV 'outside the studio' records were allocated BR/CR matrix numbers from October 1925 and the series ran to CR999 which was the closing side of the prelude to Dream of Gerontius at the Royal Albert Hall on 26/2/27.
Thereafter 1000 to 1199 was allocated in advance to the Mobile Unit and waxes were cut in the newly-commissioned van using this sequence. Other 'remote' records made by  'phone relay, via the GERRARD telephone exchange for all London recordings continued from BR/CR1200.

The van had its clerestory roof damaged by a low bridge on its first outing and I surmise was off-duty for repairs for a while.

Similar records by Columbia were normally relayed to the Petty France HQ and once the lease had lapsed on Gloucester House HMV relayed the sound to the Small Queens  Hall 'D' Studio unless they were using the van.

Memories of a Musical Dog​​

BBC TV  'Ominbus'  broadcast
27 May 1988

'Nipper', the little terrier immortalised in the famous 'His Master's Voice' trademark, takes Omnibus on a nostalgic journey from wax cylinder to compact disc to celebrate the centenary of the gramophone.

First demonstrated by its inventor Emile Berliner in May 1888, the gramophone rapidly grew from a nursery toy to become an indispensable part of entertainment in the home.
