I received this from a engineer of the local radio station in Youngstown Ohio who had worked for many local stations for over 50 years. From the 1966 Collins Catalog The only one of its kind on the market with so many advanced and deluxe features, the Collins 212H -1 is a three channel remote amplifier that provides adequate facilities for most remote applications. The 212H -1 is transistorized throughout and is built into a highly punishable thermoplastic and vinyl -clad aluminum case. A handle is mounted on the rear chassis to allow quick and easy handling between remote locations. A snap -on cover of durable thermoplastic protects the panel, controls and VU meter. The unit is completely self- contained and operates from REMOTE AUDIO fourteen 1.5 volt flashlight batteries. These batteries supply power to the amplifier for about 200 hours. The supply is interlocked with the headphone jack so that the unit requires headphones to be plugged in before it becomes operational. The VU meter indicates remaining battery voltage. A built -in phono equalizer on two of three channels provides instantaneous switching between two phonos and a microphone, or between three microphones. A built -in multiple tone generator allows a quick response check of the remote line or provides a standby tone of 100, 1000 or 5000 cps.
