A LUMIN STREAMING SYSTEM With 60W of amplifying power, LUMIN M1 is proof that an all-in-one can deliver for audiophiles. The same LUMIN musical delivery, with integrated amplification


The new Lumin M1 relies on two TI TAS5558 chips with their companion TAS5624A (one per channel) which convert a digital pulse-coded signal (PCM) to a pulse width-modulated signal (PWM). The PCM signal is multiplied by at least one derivative to obtain a sufficient sample rate for the PWM signal. The TAS5624A is a thermally enhanced class-D power amplifier based on the TAS5614A chip which uses large Mosfets for improved power efficiency and a novel gate drive scheme for reduced idle losses at low output signals, leading to reduced heat sink size. The TAS5624A uses constant voltage gain. The internally matched gain resistors ensure a high power supply rejection ratio, giving an output voltage dependent only on the audio input voltage, supposedly free from any power supply artifacts.

In this very direct conversion process, the main issue remains the prediction and address of nonlinearities and noise through sophisticated low-pass filtering and feedback techniques or DSP. The TAS5558 chipset used by Lumin is originally an 8-channel digital pulse width modulator with digital processing and sample rate conversion. As its ASRC consists of two separate modules which handle four channels each, it's possible to support two different input sampling rates. Lumin have nonetheless chosen a single sample rate of 176.4kHz which provides full compatibility with both PCM and DSD files.
