oldaudio, Tandberg series 15 audiorecorder

Here you see the background from the machine: the settings for an adequate take-up. From left to right: two turnknobs for the tone of the sound out, the VU meter, beneeth this meter two ringknobs to tune the level for microphone and/or the line in, then the take-up switch, and the buss-in for the microphone. The take-up switch also operates the amplifier only. Righthand down a little switch for pause. Line in and -out buss on the backside, as the headphone.
With the combined potmeters for microphone and line you can fine set the level for a mix AND you can hear that mix by the headphone or the loudspeaker.
The recorder has been used for audible purpose only. There is a manufacturers extra head for free head purposes (tape-slide codes), this head has been disconnected. However, it can be undone.

As simpel as can be (or as quick as can be): the taperunhandle has an operatingfunction in four directions. From the center: up is "brakes loose", down (foto) is "taperun ready" (unlock the pausebutton),
lefthand is "tapewinding to left" and righthand is "tapewinding to right". You will never, and I mean NEVER, be mistaken by uncertain commands what the machine ought to do. Each command explains itself. You want intuitivity? Here it is.

From the wellknown Scandinavian manufacturer Tandberg: the series 15.
