NASH’s Bluetooth® module and your smartphone/tablet. The NASH is a high efficiency low power design, therefore very low power is lost in heat. Anyway an adequate air flow is recommended. Avoid smoke, moisture, dirt and liquids from reaching the unit. Please note that any signs of abuse will void warranty coverage. - Page 8 M2Tech NASH MC/MM PHONO PREAMPLIFIER REVISION P A – JUNE 2018 www.m2tech.biz Copyright © 2018, M2Tech Srl...

A more prolonged press while the NASH is on will cause it to switch off. 2) Standby LED. When the NASH is in standby mode, this LED blinks to indicate to the user that the device can be switched on by the included remote control. This LED is steadily lit during the firmware update procedure. - Page 10 M2Tech NASH MC/MM PHONO PREAMPLIFIER REVISION P A – JUNE 2018 www.m2tech.biz Copyright © 2018, M2Tech Srl...

Connect the stock wall adaptor to the NASH power input (Fig. 2, 15) and to a wall outlet. NOTE: If you also own the Van Der Graaf MkII and you with to power the Nash with it, do not connect the stock wall adaptor and connect the NASH to the Van Der Graaf MkII instead, using one of the 4-pin cables provided with the latter. - Page 16 M2Tech NASH MC/MM PHONO PREAMPLIFIER REVISION P A – JUNE 2018 www.m2tech.biz Copyright © 2018, M2Tech Srl...

Page 17: Using The Nash
7. Using the NASH At activation, the NASH spends a little time to ensure that all supplies reach their nominal levels, during which the model name is displayed. After the activation delay is expired, some general operational information is shown on the NASH display: the selected source, MM stage gain (not for line inputs) and the high pass filter setting (not for line inputs). -

7.2.2. MC GAIN: Setting the gain of the MM stage when the MC input is used When the MC Input is used, the gain chain of the Nash is made of three stages: the MC preamp, the MM first stage and the MM second stage. The MC preamp gain is set by the rear panel gain pot (Fig.2, 6). -

7.2.3. MC FILTER 16Hz: setting the high pass filter for the MC input The NASH is provided with a high-pass (anti-rumble) filter. This filter cuts low frequencies below 16Hz and is very useful with warped records. Also, the 16Hz filter complies with the new IEC curve used in modern records, which adds a 16Hz high-pass to the standard RIAA curve. -

11. Considerations on NASH gain and output level The NASH can deliver up to 95dB total gain on the MC input, and up to 65dB on the MM input. These values largely exceed the usual gains for a phono preamplifier, which range between 40dB for an MM input and 60-65dB for an MC input. - Page 28 MC preamplifier powered by a proprietary discrete components ultra-low noise dual regulator. Thanks to these low-noise amplifiers, the NASH can deliver at least 2.5V at its output with every cartridge model, with great noise performance. This means that the NASH has an output value which is aligned to that of digital sources like DAC’s, CD/DVD players and...
