harsh computer environment. This improves the signal-to-noise and dynamic range performance dramatically over a typical (or even professional) sound card. This manual assumes you have a basic understanding of A/D conversion and digital audio. If after reading the manual you need additional tech support, or if you have comments or suggestions, we invite you to contact us directly by any one of the following methods: MIDIMAN 45 East St.

Features • High-quality, 24-bit stereo, A/D converter. • Unbalanced analog inputs on independent left and right 1/4” jacks. • S/PDIF digital output on an RCA connector. • Transformer-coupled S/PDIF eliminates potential system ground loops. • Front panel input signal level displays for each channel. • Jumper-selectable input levels. • Compact desk-top size: 6.3” x 3.6” x 1.2”. Panel Description Front Panel 1. Sample Rate Indicator LED's: Show the current A/D sample rate (either 44.1 kHz or 48 kHz).

7. S/PDIF Out: This female RCA jack outputs a standard S/PDIF digital audio signal. The S/PDIF signal is "stereo," containing both left channel and right channel audio data. The S/PDIF data rate will be determined by the Sample Rate selector button on the front of the Flying Calf.

After all connections are made, power up the Flying Calf by pressing the power button on its front panel. IMPORTANT: Before powering up the Flying Calf, turn off or turn down any amplifiers, mixers, or audio converters connected to the Flying Calf's S/PDIF output. Since it may take several milliseconds for the Flying Calf to output valid S/PDIF, you may hear a slight "pop" or “buzz” sound while powering up if you are monitoring the S/PDIF out .

The level of the analog signal that goes into the Flying Calf should be adjusted for optimum A/D sampling quality. For best conversion, the input signal should have enough amplitude to take advantage of nearly all 24 bits of A/D resolution. In other words, peak levels of the incoming audio signal should be loud enough to approach the A/D converter's maximum acceptable (full-scale) signal level. The Flying Calf front panel A/D Input Level indicators aid in this adjustment.

Internal Jumper Settings There are four configuration jumpers inside the Flying Calf chassis. Typically you will never need to open the Flying Calf and adjust these jumpers. For some applications, however, it may be required. JP2 and JP3 are used to set the input levels for the left and right channels. JP1 consists of two jumpers which are used to set the copy-protect status of the Flying Calf. IMPORTANT: Always power off the Flying Calf and disconnect the power adapter before removing its top.

Right Analog In “Standard” Level Right Analog In “+6” Level JP2 Left Analog In “Standard” Level JP2 JP3 Jumper JP2 and JP3 Settings JP3 Jumpers JP2 and JP3 control the input levels to the LEFT and RIGHT audio channels, respectively. When set to the "Standard" position, they accommodate most signals (-10 dBV nominal). When set to the "+6" position, they can accept signals that are 6 dB weaker (-16 dBV nominal). The positions and settings of these jumpers are shown in Figure 3 and 4.

However, if SCMS is enabled: When ORIGINAL is installed, data is flagged as a COPY. When ORIGINAL is not installed, data is flagged as ORIGINAL. Troubleshooting Symptom: When power is applied, there are no LED's lit on the Flying Calf's front panel. Solution: Make sure the power supply is properly plugged into the unit and into a live wall source or power strip. Also verify that the Calf's Power button is pushed (and latched) in.
