5. MODE OF OPERATION

The ULTRAMATCH is an all-purpose device for modern recording studios. It provides not only sample rate

conversion but also format and standard conversion, and additionally allows you to manipulate part of the

information transmitted with the audio signal. The ULTRAMATCH features no bypass mode, since input and

output signal are practically identical if the same sample rate is applied to both input and output.

+ Note: Special data formats for backup purposes, that do not contain audio data (streamer

applications etc.) cannot be processed with the ULTRAMATCH.

5.1 Basic Settings

When powered up, the ULTRAMATCH automatically generates a basic setting suitable for most applications,

thus relieving the user from unnecessary work. The input to be activated is automatically selected by a simple

priority logic, and the active mode of operation is indicated by the corresponding LED.

5.2 Elimination of Errors

The ERROR LED indicates if a valid signal is recognized at the input of the ULTRAMATCH. If a device con-

nected to the output of the ULTRAMATCH does not work properly, the wrong format has probably been se-

lected. Change the format of the output signal by pressing the FORMAT switch.

5.3 Conversion to 32 kHz

Though 44.1 kHz is a generally accepted standard for digital audio signals, there are good reasons for convert-

ing the signal to 32 kHz: This sample rate is not only compelling for some applications (digital broadcasting

systems, long-play mode) but also necessary if memory is critical (one minute of sample data requires only 7

Mbytes instead of 10 Mbytes).

5.4 Emphasis Correction

If the EMPHASIS switch is set to AUTO, the emphasis information is transmitted to the output as received at

the input. If the emphasis bit is wrongly set due to incorrect pre-processing or defective software or hardware,

press the EMPHASIS switch to suppress the output of the emphasis information. The EMPHASIS LED indi-

cates if an emphasis-coded signal is received at the input.
