FCC Class B and CE Compliance

WARNING: This equipment has been tested and found to comply with the lim­its for a CLASS B digital device, pursuant to Part 15 of the FCC Rules. These lim­its are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instruc­tions contained in this manual, may cause harmful interference to radio and tele­vision communications. However, there is no guarantee that interference will not
occur in a particular installation.

If this equipment does cause harmful interference to radio or television recep­tion, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures: 1) reorient or relocate the receiving antenna; 2) increase the separation
between the equipment and the receiver; 3) connect the equipment into an outlet
on a circuit different from that of the receiver; 4) consult the dealer or an experi­enced audio television technician.

NOTE: Connecting this device to peripheral devices that do not com­ply with CLASS B requirements or using an unshielded peripheral
data cable could also result in harmful interference to radio or televi­sion reception.

The user is cautioned that any changes or modifications not expressly approved
by the party responsible for compliance could void the user’s authority to oper­ate this equipment.

To ensure that the use of this product does not contribute to interference, it is
necessary to use shielded I/O cables.

This product also complies with European CE require­ments.

Overview

Thank you for choosing the Flying Calf A/D, professional 24-bit
external A/D converter. The Flying Calf captures incoming audio
with its high-quality Analog-to-Digital (A/D) converters and out­puts it digitally via the popular S/PDIF digital audio format. The
Flying Calf is, therefore, the perfect companion for computer digi­tal audio cards, DAT machines, or any other digital audio device
that requires high-quality A/D conversion. Since the Flying Calf
is external, it moves the A/D converters out of the noisy and

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:

Panel Description

Front Panel

1. Sample Rate Indicator LED's: Show the current A/D sample

rate (either 44.1 kHz or 48 kHz). These LED's also double as
power indicators – one of the LED's is lit any time the unit’s
power is turned on.

2. Sample Rate Selector Button: Selects the current A/D sample

rate. When this button is out, the sample rate is set to 44.1
kHz. When the button is in, the sample rate is set to 48 kHz.

3. Input Level Displays: These LED display ladders accurately

depict the incoming signal levels at the A/D left and right
channels.

4. Power Button: When this button is in (and the power adapter

is properly plugged in), power is applied to the unit and one
of the Sample Rate Indicator LED's will be lit. When the but­ton is out, the Flying Calf A/D is powered down.

Rear Panel

5. Power connector: For connection to the Calf’s power adapter.

The Flying Calf uses a 9 Volt DC, 500 milliamp (or greater),
center-pin positive supply.

6. Analog In (Left and Right): Analog audio inputs to the

Flying Calf’s A/D converter. These 1/4" jacks accept unbal­anced line-level signals. Each jack provides a "tip/sleeve"
type of connection.
