Getting Started

Section 1

Output Level

This knob controls the overall level of the output signal, and ranges from -20 to +20dB.

Meter Select Switch

This switch allows you to select display metering of either the digital or analog output signal. The analog level is scaled in dBu, while the digital level is scaled in dBFS.

LightPipe™ Meter

This meter displays either the analog or digital output signal.

Dither Switch

This switch is used to select the type of dither algorithm including: TPDF, SNR2 , or None. Dither is random noise that is added to the audio signal which effectively eliminates the harmonic dis- tortion created by truncation. See the “Truncation” graph in section D.2 of the Appendix. The LED will be lit RED for the SNR2 or GREEN for the TPDF dither algorithm. When the LED is off, dither- ing is not in use.

Shape Switch

This switch selects either the Shape 1 or Shape 2 psycho-acoustic noise-shaping curve. Shape 1 utilizes a mild psycho-acoustic curve, while the curve used in Shape 2 tends to be more aggres- sive. Please see the "Noise Shaping" graph in section D.1 of the Appendix. The LED will light GREEN for Shape 1 and RED for Shape 2. When the LED is off, the noise-shaping effect is not in use.

Sample Rate Switch

This switch selects the digital output sample rate of either: 44.1, 48, 88.2, or 96 kHz. The LED will not be lit for 44.1 kHz, GREEN for 48 kHz, RED for 88.2 kHz and YELLOW for 96 kHz.

Word Length Switch

Selects output wordlength of 16, 20, or 24 bits output resolution. The LED will not be lit for 16 bit, GREEN for 20 bit, and RED for 24 bit.

Output Format

Selects the AES/EBU or S/PDIF digital output format. The LED will be lit green for AES/EBU and red for S/PDIF.
