2. Introduction

The Sirius 600 audio input and output cards provide the necessary conversion to enable

stereo analogue sources or destinations to be routed through any Sirius 600 digital crosspoint

card, and to be used in combination with the Sirius 600 AES digital audio cards.

• 4790: Eight channel stereo analogue audio input ADC

• 4791: Eight channel stereo analogue audio input ADC

• 4795: Eight channel stereo analogue audio output DAC

• 4796: Eight channel stereo analogue audio output DAC

These cards can therefore be directly substituted for the AES input, or AES output cards, for

users requiring an analogue or mixed Sirius 600 audio router. The hybrid cards can also

perform the same audio modify functions as the digital cards, allowing use in a mixed

mono/stereo environment. These features are documented in Section 3.5.

The cards have input and output gain adjustment with a range of +15 to +24 dBU at 0DBFS,

these are user adjustable for each channel and stored in non-volatile RAM. The output card

can also generate test tones to assist with the lining-up process. These features are

documented in chapter 3.

These cards operate in synchronous or asynchronous AES environment. If a valid AES11

reference is supplied to the Sirius 600 frame, this provides clean click-free switching, and

enables all the audio modify features. In an asynchronous Sirius 600 frame with no reference,

the input card free-runs at 48 kHz, and the output card converts from any sample rate in the

range 32 to 54 kHz, although no audio modify features function.

The DAC Auto detect determines which reference is selected:

• ADC Reference = I2S

• No Reference = AES Free-runs at 48 kHz,

Both cards have on-board circuitry for input and output monitoring via the Sirius 600

monitoring card.

There are also two builds of connector panel to accompany the input and output cards:

• 1767: fitted with 50-way D-type plug for 8 stereo inputs

• 1768: fitted with 50-way D-type socket for 8 stereo outputs

4790 and 4795 cards can only be used with the following 'series 1' crosspoint cards:

• 3906: 128x32 HD/SDV/Audio Crosspoint (4U/7U frame)

• 3907: 128/32 SDV/Audio Crosspoint (4U/7U frame)

• 3909: 256x64 SDV/Audio Crosspoint (16U frame)

• 4907: 128x32 Audio Crosspoint (4U/7U frame)

• 4909: 256x64 Audio Crosspoint Audio/AES/Data/Timecode (16U frame)

Sirius Audio Converters www.snellgroup.com Introduction

4791 and 4796 cards can be used with any of the 'series 1' crosspoint cards listed above, and

the following 'series 2' crosspoint cards:

• 3908: 256x32 HD/SD/Audio Crosspoint module (16U frame)

• 3912: 128x32 HD/SD/Audio Crosspoint module (4U and 7U frame)

• 3913: 256x64 HD/SD/Audio Crosspoint module for Sirius Gold

• 3962: 128x32 3G/HD/SD/Audio Crosspoint module (4U and 7U frame)

• 3969: 256x64 3G/HD/SD/Audio Crosspoint module (16U frame)

• 4905: 256x32 Audio Crosspoint module 16U frame)

• 4911: 128x32/128x64 Audio Crosspoint module (4U and 7U frame)

• 4913: 256x64 Audio Crosspoint module for Sirius Gold

3. Hybrid Audio Cards

3.1 4790 Input Card

The 4790 Input Card has eight inputs of stereo analogue audio, with separate balanced left

and right channels and non-volatile gain adjustment. These are converted to digital signals of

an internal format designed to feed Sirius 600 AES or Audio Hybrid output cards via any

Sirius 600 digital crosspoint. If the frame is supplied with a valid AES11reference, which can

be in the range 32 to 54 kHz, all digital outputs from the card are aligned to the reference.

With no reference detected the card runs at approximately 48 kHz, as set by an on-board

oscillator. The outputs have 24bit resolution with channel status indicating Professional,

Locked (with frame reference) or Unlocked, Flat (no emphasis), Stereo, with no aux bits. The

sample rate status is flagged as '48 kHz' if the on-board crystal locks to the frame reference,

otherwise it is set to 'not indicated'.

The front edge of the card has push buttons for adjusting and storing the gain setting, a HEX

switch for selecting the channel, and a piano type DIL switch for mode selection. A green LED

indicates that power is present, a red LED to indicate that no reference has been detected,

and a tri-color LED to show gain status. Section 3.1.1 describes the Gain adjustments.

3.1.1 Adjusting the Gain

Fig 2. shows the front edge switches. Only position 4 of the piano type DIL switch is used.

When set Down (ON), the UP and DOWN buttons increment and decrement the gain of the

mono analogue channel, see Table 1.

Note:

This card only works with series one crosspoint cards.

At large signal levels the gain increment is 0.25dB, and at lower levels it is 0.025dB. The UP

and Down buttons are auto-repeating at a rate of 2 steps per second if kept pressed. When

the required gain level has been achieved, it is committed to non-volatile memory by pressing

the STORE button, if this is not pressed the channel reverts to the last saved gain setting

when the module is re-powered. A tri-color LED indicates the status of the gain adjustment for

the current channel:

The switch position for normal operation is Switch 5, position 4 UP (INHIBIT).
