New Technologies

In the MMC 1 SPL`s new SUPRA operation amplifiers are used throughout. They operate at 120 V operating voltage. During a four-year period, SPL has researched this discrete operation amplifier, until the basis of a new generation of analogue audio technology was found. The SUPRA operation amplifier obtains a signal-to-noise ratio of 116dB with an headroom of 34dB. The dynamic range amounts to 150dB with a frequency bandwidth ranging to 200kHz.

With these basic specs, the MMC 1 is beyond the requirements of today's PCM digital formats up to 24 bit and 192kHz sampling rate or DSD digital format with 1 bit and 256 fs.

It is not to be expected that digital technology will offer an environment in foreseeable time, in which the MMC 1 could become a "bottle neck".
