Sony M-540v Microcassette Recorder

The Sony M-540v is a full-featured unit designed to make voice recording simple while maintaining high-quality sound reproduction. This unit's conveniences include Voice Operated Recording (VOR), which activates the recorder only when audible sound is present, to conserve tape and eliminate soundless passages, and two-speed record and playback, which gives you the option of recording on a standard microcassette at either normal speed of 2.4 centimeters per second or at half that speed at for extended recording or dictation sessions.

A three-digit counter makes it easy to find a specific location on the tape for rapid access and editing, and one-touch recording simplifies play and record operation. Sonymatic automatic recording level control uses advanced circuitry to ensure correct recording sound levels for any recording situation, and the M-540v's clear-voice function enhances voice quality during playback.

The unit's 24-hour battery life, made possible by advanced technology that extends battery power beyond previous limits, is monitored by an LED indicator. Automatic shutoff conserves battery power, reduces mechanical wear, and pops up the buttons to alert you that recording has stopped.
