max. 1.4 VRMS output resistance: max. 5 . S/N-ratio: >85 dB at maximum volume Max.

noise voltage in mute mode: < 10 V (BW: 20 Hz... 16kHz)

- one pair of four-fold oversampled D/A converters supplying a pair of SCART-outputs.

output level per channel: max. 2 V RMS, output resistance: max. 0.5 , S/N-Ratio: >85 dB (20 Hz... 16 kHz)

4-2-1-4 NICAM plus FM/AM-Mono

According to the British, Scandinavian, Spanish, and French TV-standards, high-quality stereo sound is transmitted digitally. The systems allow two high-quality digital sound channels to be added to the already existing FM/AM-channel. The sound coding follows the format of the so-called Near Instantaneous Companding System (NICAM 728). Transmission is performed using Differential Quadrature Phase Shift Keying (DQPSK. Table below offers an overview of the modulation parameters.)

In the case of NICAM/FM (AM) mode, there are three different audio channels available: NICAM A, NICAM B, and FM/AM-mono. NICAM A and B may belong either to a stereo or to a dual language transmission. Information about operation mode and about the quality of the NICAM signal can be read by the controlling software via the control bus. In the case of low quality (high bit error rate), the controlling software may decide to switch to the analogue FM/AM- mono sound. Alternatively, an automatic NICAM-FM/AM switching may be applied.

4-2-1-5 German 2-Carrier System (DUAL FM System)

Since September 1981, stereo and dual sound programs have been transmitted in Germany using the 2-carrier system. Sound transmission consists of the already existing first sound carrier and a second sound carrier additionally containing an identification signal. More details of this standard are given in Tables below. For D/K very similar system is used.
