Sampling Rate
When a sampling rate is selected for recording, all tracks are recorded at the selected sampling
rate. Sampling rates are selected among common rates from 32 kHz to 192 kHz. Additionally, non-
standard sampling rates can be applied when the 788T is word clocked from an external source
(clock sources between 32 kHz and 192 kHz). When recording off-speed sampling rates, fi les will be
stamped with the rate closest to the internally generated frequency.
Sampling Frequency and Audio Bandwidth
The sampling frequency is expressed in samples per second (hertz) and defi nes the number of times
in a second that the analog audio signal has been measured. Sampling frequency determines the
audio bandwidth, or frequency response, that can be represented by the digital signal. A quick esti-
mate of the maximum bandwidth capable of being represented at a given sampling rate is maximum
analog frequency = sampling frequency/2. Higher sampling frequencies allow for wider audio
bandwidth.
The 788T generates the following sampling rates:
• 32 kHz
• 44.1 kHz
• 47.952 kHz
• 47.952 kHz “F Mode”
• 48 kHz
• 48.048 kHz
• 48.048 kHz “F Mode”
• 88.2 kHz
• 96 kHz
• 96.096 kHz
• 96.096 kHz “F Mode”
• 176.4 kHz
• 192 kHz
See Time Code
for more information about F Mode sample rates.
Considerations When Recording With High Sample Rates
Increasing the sample rate above 48.048 kHz requires certain settings to be adjusted and imposes
certain limits to some features. Increasing the sample rate above 96.096 kHz furthers these require-
ments. It is recommended to save settings for work fl ows with a high sample rate, so they can be
easily recalled.
