High-Quality
Amplifiers
The mains power
switch, speed selector switch, Start/Stop button, and button for the tone arm
lift comprise the operating elements of the EMT 938 BDR (Broadcast Disk
Reproducer). Both Start and i.e., run-up
of the turntable platter and platter braking, are accomplished in less than 500
milliseconds. The unit cantherefore be started precisely at any syllable in the
groove.
To facilitate
locating a desired point on the record (such as the beginning of the
modulation, or a specific cueing point), theplatter rim extends 2,4 cm beyond
the edge of an LP, enabling the record platter to be turned back and forth by
hand. A phone jack is provided for connecting stereo headphones.
The EMT 938 BDR is
now equiped with a synchronization indicator, which illuminates as soon as the
started turntable platter has reached the selected speed.
The front view shows
the level controls of the audio amplifiers. The insertion of a pre-preamplifier
for moving coil pickup cartridges is indicated by a coloured dot.
Jacks for external
connections are located on the rear side of the EMT 938 BDR. Printed legends
identify the functions of the jacks.
