include digital multitracks, digital mixers, or a converter that turns 8

analog signals or ADAT 8-channel optical into a TDIF format signal.

On the external breakout cable that connects to the PCI card, you will find

connectors for all other inputs and outputs. Coaxial S/PDIF I/O on

female RCA jacks accepts a digital input from a variety of sources, and

sends a digital output from your computer via the Delta software. The

Delta Control Panel software gives you several options for digital output,

such as setting copy protection bits, plus advanced settings that will

allow the output of a Dolby Digital 5.1, or “AC3” signal. The breakout

cable BNC connector is a wordclock output which may be used to

synchronize other digital devices to the Delta TDIF board. Wordclock is

a sampling clock signal which automatically operates at the present Delta

TDIF sample rate, whether that sample rate is derived from the Delta

TDIF’s internal clock, S/PDIF input, or TDIF input.

Analog jacks on the Delta TDIF breakout cable, two for input and two for

output, are RCA phono type female jacks. Although the RCA jacks

typically allow connection to unbalanced (typically consumer) line level

connections, +4dBu level unbalanced equipment may be connected to the

Delta TDIF’s RCA jacks. However, sometimes +4dB signals may be too

hot for these analog inputs. Consult the user guide for your particular

device. On the analog outputs, the Delta Control Panel software provides

line level switches between -10dB and -4dB, labeled “Consumer.” These

software switches allow you to adjust your stereo output signal to the line

level of the receiving device.

NOTE: In order to preserve its high dynamic range and minimize

distortion, the Delta TDIF does not have microphone pre-amplifiers

built into it. Therefore direct connection to a microphone is not

recommended. Instead run the microphone signal through a

microphone pre-amp and then connect the pre-amp output to the

input of the Delta TDIF.

The Digital Monitor Mixer

The Delta TDIF PCI Audio Card has a hardware digital audio mixer built

into its PCI controller chip. It accepts digital audio streams from all

hardware inputs and all outgoing software audio devices, mixes them

with 36-bit internal precision and then provides the mixed output to one

or more locations. For the purpose of monitoring, the output of the mixer

may be routed to the pair of Delta TDIF analog outputs and the S/PDIF

digital output simultaneously (SP/ANA stereo pair) . The output of the

mixer may also be routed to the Delta TDIF Audio Card’s TDIF OUT1

and OUT2. At the same time the mixer may be used for stereo mix-down,
