Pot/Trim selector assigns either as the input sensitivity controls. They set input sensitivity with range from mute to +4dB=-6dBFS. Precision 10 turn trimpots allow for precise level alignment while the knob is intended for quick “on the fly” adjustments. Refer to "Alignement” for details. Sample rate selection. Sets the desired sample rate. When used with external clock select FS closest matching that of supplied external wordclock. Introduction to Stereo Series Converters Peak meter in -dBFS.
Stereo192ADC internal trimpots and jumper assignments (remove top cover to access) Stereo192ADC internal trimpots and jumper assignments (remove top cover to access) Jumper JP5: Wordclock input 75 Ohm termination. Connect this jumper when Stereo96 ADC is the last destination in a chain fed by external wordclock source and the cable is long (above 6ft). For short cables and wordclock sources with unknown drive capability JP5 should be left unconnected (unterminated) (retain the jumper on one pin only).
Typical Setup Balanced signal source Stereo192 ADC is equipped with 2 XLR analog inputs. For best signal to noise performance it is recommended the signal source has a typical low impedance output with standard +4dB line level balanced signal. Alternatively a weaker unbalanced signal source can be used as described in subsequent paragraph. In typical setup the ADC is running on its internal clock with the rest of equipment synchronized to Mytek clock either through digital output signal or wordclock.
Unbalanced Signal Source Operation Analog Input Alignment When using precision trimpots analog input level needs to be aligned using an approx 1kHz sinewave fed from +4dB balanced source. The alignment does not affect audio quality, only input sensitivity. The alignment is performed using 10 turn trimpots. A small tweaker or screwdriver is necessary. You have to arbitrarily decide what will be your studio "0 VU" analog/digital reference level. It is usually between -20 and -14dB.
Are printing final CD master, we do not recommend recording too hot. There is no sonic benefit of pushing the level up to 0dBFS. A healthy 1-23 dBs headroom allows more freedom in later processing and mixing of recorded tracks. The red peak light is triggered digitally when 1 or more samples are overload. It's not recommended to peak frequently although occasional overloads might be acceptable.
and must not be used for critical projects downsampling. Some such as Faulkner Downsampler (http://www.audiosignal.co.uk/freeware.html) provide excellent results for 88.2>44.1 but don't work for 96k. 88.2k is also easier to upsample to DSD. 96k sample rate, has in our opinion, a marginally better perceived sound quality than 88.2k but the difference is very small and difficult to perceive for most people. If the record is going to be mixed in analog domain, 96k might be a desirable choice for tracking.
