Page 4: Introduction
Introduction Creating authentic tape saturation effects. The sound becomes warmer and more powerful, elimina- ting the harshness of digital recordings. Precise reproduction of: - tape saturation effect - hysteresis effect - harmonic characteristic - linear and non linear trans- mission characteristic Modified reproduction of: - level behaviour - high frequency damping... -

Indicators and meters: is equipped with PPM displays for input and ACHINE output levels. The first LED of each input and output meter is a signal (S .) LED which illuminates when a compatible digital data stream is present at the inputs. The LEDs are a first indi- cator to check the data stream. -

Connections Before connecting the M ACHINE all connected units. The rear panel provides AES/EBU- and S/P-DIF-inputs and outputs. Any additional channel, status and user-bits are passed through unaltered, and the outputs can be used at the same time if required. The M operates with 24 bit word width. -

The software bypass also compensates for the 5ms time delay between processed and unprocessed signal. -

The higher the D the more intense gets the saturation of RIVE the tape. While increasing the D increase, too. Compensate for this by reducing the O value (see 5) and monitor the O tively the perceived loudness will increase more dramatic than the actual PPM value! Recommended values are 3 to 8 for the D which corresponds with +10 dB to +15 dB for the actual D... -

The D metering shows the recording level of the RIVE EVEL “virtual tape machine”. The display range is -10 dB to +21 dB. The D ist adjusted with the D RIVE EVEL The O PPM meters show the peak level after the O UTPUT control (see 5). -
