RIAA. The EVO PHONODAC TWO has not a specific RIAA/IEC curve, but it can be obtained by selecting RIAA and the high-pass filter at 16Hz (see Section 8.7).
LP’s after losing the format war against Columbia, so it’s difficult to say which curve was used for a certain record. The EVO PHONODAC TWO offers three choices, based on record’s year of cutting. RCA1 is the oldest. The newest, RCA Orthophonic, is the one on which the “New Orthopohonic”...
Same thing can be done with the EVO PHONODAC TWO , connecting the playback head of a tape recorder to its analog inputs (eventually via an impedance adaptor), adjusting the gain as required and selecting the appropriate equalization curve for the tape being played back.
9.5. Interfacing a cartridge or a tape head The EVO PHONODAC TWO has an input impedance which can be set to any value between 10 Ohms and 50,000 Ohms by means of a knob on the back panel. This value range...
9.6. Recording programs When acquiring on a computer with the EVO PHONODAC TWO , a suitable program of application needs to be used. Several different programs of packages are available for Windows, Mac and Linux, some of them are freeware, others need to be purchased.
Apple OSX since the 10.6.4 release, without the need for any driver: It is sufficient to connect the EVO PHONODAC TWO to own Mac with an USB cable (not in stock) to have it recognized by the Mac, which will then include it in the audio devices list, as shown in Fig.
The EVO PHONODAC TWO is able to transfer music files recorded with the DSD format. A player able to send DSD data to the EVO PHONODAC TWO in a standard format handled by the DAC must be used. As an example, the configuration of Audirvana necessary for DSD files playback is shown in Fig.
USB Audio Device Class support. When in doubt, ask the creator of your Linux distribution for more information. As with Apple OSX, with Linux it is necessary to choose the EVO PHONODAC TWO as the output device. This can be done accessing the audio management window and setting the various parameters as shown in Fig.
10.3.1. Installing the Windows driver First, it is necessary to download the driver from the M2Tech website at (http://www.m2tech.biz/it/evoPhonoDAC.html) Here you’ll find the compressed folder containing all installation files. It’s a self-extracting file: automatic extraction is launched by double-clocking on its icon, as shown in Fig.
