The users guide was excellent. It provided the information neeeded to connect and control the Crate system. Nothing was left to chance

Recalibrate Converters � Used to calibrate DC offset of the A/D and D/A converters. When the Lynx L22 driver first loads, the converters are calibrated for optimum fidelity. Over time temperature changes inside your computer may cause the DC offset to drift slightly. Because of this, Lynx recommends recalibration 15 to 30 minutes after your computer has been turned on and whenever significant changes in room temperature occur. Dither Type � Provides selection of the type of dither used on all record channels. The selection may be one of the following: None - Dither is disabled. Volume processing utilizes rounding prior to truncation. Triangular - Enables the addition of triangular probability density dither. This type of dither is free of data-dependent noise modulation effects, but decreases signal-to-noise ratio by 4.8 dB. Triangular is the preferred dither type in most cases. Shaped Triangular - Enables the addition of shaped triangular probability density dither. This type of dither is essentially a high-pass filtered triangular dither that places most of the dither energy at higher frequencies making it less audible to the human ear. Shaped triangular dither also decreases signal-tonoise ratio by 4.8 dB. Rectangular - Enables the addition of rectangular probability density dither. This type of dither decreases the signal-to-noise ratio by 3 dB (less than triangular), but is less desirable because of its noise modulation effects.
