Mola Mola Makua
ESIVAHVISTIN
Analogista suunnittelua
digitaalisella aikakaudella
Makua on suunniteltu mahdollisimman rehelliseksi ja läpinäkyväksi esivahvistimeksi. Se on hämmästyttävän immuuni mitä tulee esimerkiksi verkkovirran laatuun, ja sen toiminta on varmaa ja täysin ongelmatonta.
Makuan koteloon on jätetty runsaasti tilaa vaihtoehtoisille extroille, kuten DAC- ja/tai phono-kortille.
Kaikki viisi sisääntuloa on helposti valittavissa kytkimellä joko XLR- tai RCA-tuloliitännöille. Makuan relepohjainen voluuminsäätö ohjaa suoraan antoliitäntöjen vahvistusta.
Maailmanluokan linjatasoinen esivahvistin!

Phono stage
What was originally intended to be a simple RIAA add-on for the Makua Preamp has quickly spiraled into the quietest and probably most versatile phono stage ever built. MC/MM input stages are optimized for current noise and voltage noise respectively. Unlike the more common arrangement of an MC head amp feeding into the MM stage, the two stages are fully independent, realizing an equally short signal path for both. Input gain is switchable in 5dB steps over a 40dB range.
DAC add-on
The converter is a two board stack that fits into one of the option slots in the preamp. On the first board, all incoming digital audio is upsampled to 3.125MHz/32 bits and converted to noise shaped PWM. On the other board are two mono DACs, in which a discrete 32- stage FIR DAC and a single-stage 4th order filtering I/V converter, convert the PWM into analogue with a breathtaking 130dB SNR.
With the knowledge in hand to design minimally invasive electronics without needing to be minimalistic, we decided that our preamp should be complete, very complete.
The basic Makua is an extremely transparent gain stage and a programmable routing matrix. The chassis has ample room to fit optional extras, most notably a DAC and a phono stage.
The 6 preset buttons are programmable via RS232 or Bluetooth to access any combination of channel, processing and routing.
In a system with mainly digital sources, the preset buttons would be programmed to select between them.
Vinyl lovers on the other hand might want to use several buttons to select the same turntable but with different EQ settings to suit their large collection of historic LP’s…
