The immersive science of Audio Equipment, brought to you by {name}

Ariel Cabello

Made by The Brush Development
Company, 3405 Perkins Ave, Cleveland Ohio, this “Soundmirror”
was one of the first (if not THE first) domestic tape recorders made in
the the United States (or anywhere else for that matter).
Designed to use magnetically coated quarter inch PAPER tape, (although
the later conventional plastic tape would be OK as well) the BK401 was
a three-motor, full-track mono recorder with a single speed of 7½
ips.
Frequency response was about 100 to 5kHz only.
A five-watt amplifier drove a front mounted six inch round PM speaker,
record bias was 30kHz and record level was shown by a 6E5 magic eye tube.
The simple pushbutton transport controls consisted of forward, reverse,
start, stop and record, with a tone control and playback volume, record
level and record/play mode selector switch.
