Remarks

• The REMA tonica RX 80 is a hi-fi stereo control unit manufactured by REMA Stollberg and developed as the successor to the REMA Toccata.

It was distinguished compared to previously manufactured control units by some innovations that increase the utility value. The tonica has a 4-band tuner for the wavebands LW, MW, KW and UKW, which is common in the HiFi class, whereby the three AM ranges have no special features.

• The FM tuner, whose input section is fitted with MOS field-effect transistors, is characterised by very good large-signal immunity.

It has a 75 Ohm coaxial input and its reception range reached for the first time in a control unit up to 108 MHz. A new feature was the station memory with 14 presets, which could be freely programmed with FM stations in addition to the main dial. Programming was done with the spindle potentiometers located behind a flap (which has a small compartment for storing a notepad for the memory assignments) with the help of a 12-segment LED chain below the main scale. It acts as a "moving pointer" by illuminating either one or two LEDs, and serves as a rough guide to memory location assignment. The stored stations can be selected by means of smooth-running touch keys, and a small red LED indicates the currently activated memory location. In addition to the station memories - memory location 1 is automatically selected when the unit is switched on - there is a normal frequency scale which is activated by touching the rotary knob.

• A horizontal, angular, red LED is provided as a scale pointer.
• Furthermore, the tonica has a six-part LED chain as field strength indicator, a three-part exact tuning indicator, as well as a computer AFC that switches off and on again automatically.
• The tonica's preamp features.
• Volume, bass, treble and balance, as well as the switchable aurally correct volume control (linear) and the 15 dB lowerable volume (level) are controlled by means of 3 IS A 274 via DC voltages.
• Furthermore, the unit has diode inputs for TA, TB 1 and TB 2, whereby the TB 2 socket is located on the front of the tonica.
• The power amplifier is also designed according to the technical state of the art.
• It is fed with balanced supply voltage, which is why no decoupling electrolytic capacitors are necessary.

As a special feature, two pairs of loudspeakers could be connected to a GDR unit for the first time. They are selected by two switches and switched on by the two protection relays of the power amplifiers. The two pairs of loudspeakers can be operated individually or together, whereby the output power is electronically limited when both pairs are operated, in order to avoid possible overloads of the power amplifier or the mains transformer in the then present 2 Ohm load case.

• Because of the speaker shutdown capability, the two headphone jacks are not self-switching.
• The optical design of the Tonica is modern, businesslike, independent and can be described as successful, although the plastic front panel certainly looks a bit cheap.
• There is still a certain structure and clarity despite the large number of buttons.
• The size of the tonica was chosen so that it could be combined in width and height with the components of other GDR hi-fi systems, but due to the size of the circuit, the device depth of 300 mm is somewhat greater than that of component systems.
