the Sensors of The Load & Lock-the invention of the DUAL of the Ejecting a cassette during operation. Simply reach in, the device waits in the playback waiting position for the next cassette and continues to play immediately. With the internally installed DIN adapter, the device can be operated not only on modern systems with RCA sockets, but also on older amplifiers and receivers with DIN connections. Switching is not necessary. By simply loosening the two knurled screws, the metal cover can be removed and the complete head and drive technology is exposed. If a dust lint should have formed over the years, which could affect the drive. The 6-digit tape type switch ensures brilliant sound for every cassette. The high-precision mechanics from the Black Forest ensure perfect precision for a whole cassette recorder life, without ever "weakening". The very easy-to-use ergonomic toggle switches with metal button work perfectly and without dropouts or "cracks". With the tandem potentiometer, both channels can also be controlled separately. Just hold on to one and regulate the other. Thanks to the peak level indicator, your favorite recordings can be perfectly adjusted to 1 decibel (dB)! For your own microphone recordings, the DUAL has 6.3 mm jack sockets, separate for left and right. The switchable level limiter ensures a limit at too high levels in manual level control mode. Advantage: no loss of dynamics, no constantly changing volumes as automatic control systems cause. Which device still offers so many possibilities today to let your creativity run so freely?
