Analog 8/4 Interface

The Analog 8/4 interface provides the Falcon with eight or four analog cinch outputs with 16-bit precision (20 Hz - 20 kHz). It is directly supported by all professional HD recording systems (Cubase Audio, Logic Audio, Audio Master, Audio Tracker, Zero-X).

Connecting the Interface to the Falcon

Use the special SoundPool DSP adapter cable to connect the Analog 8/4 Interface to the Falcon. The SPDIF interface can be placed on top of the Analog 8/4 Interface. Use the short D-Sub connector to connect the SPDIF port of the Analog 8/4 Interface interface with the SPDIF interface.

If you are chaining multiple SoundPool devices, connect them in the following order:

1. ADAT Interface
2. Analog 8/4 Interface
3. SPDIF Interface

Combination of SPDIF and Analog 8/4

In some cases the combination of an Analog 8/4 and a SPDIF interface of the first revision may cause unexspected trouble during record. There is an easy way to fix this problem:

1. Open the SPDIF interface

2. In the top right, close to the connector you will find nine resistors. The last one on the
right hand side is a 18 Ohm resistor (brown/grey/black/gold).

3. Replace this resistor with a new one (68 Ohms blue/grey/black/gold)

Connecting the Interface to the Mixer

Use high quality shielded audio cables to connect the output of the Analog 8/4 interface with the input of the audio mixer.

Software Installation

The SoundPool Analog 8/4 interface is supported by Cubase Audio (Version 2.06 or higher) and AudioTracker (Version 1.60 or higher). Other programs only support two track playback. For proper installation and output selection refer to the manuals of the software.

Tips & Tricks for Noise and Hum Interference

1. Ground Loops

They can be remedied with galvanically seperated line level and digital connections. Unfortunately the required transformers are quite expensive. Therefore, optical cables (TOS link) are recommend for digital connections and DI-boxes with transformators for the record send (from the mixer to the computer). Very often, this is sufficient. In very difficult cases, you can google some very good articles on the subject.

2. Digital Crosstalk

This can be remedied with galvanically seperated digital connections (optical cables) and very good SCSI cables. Very often you will find the power supply of some devices to be the culprit.

3. Electromagnetic Interference

Interference by transformers and power supplies can be remedied with balanced cables. This effect is most noticeable with mircrophones (high impedance and with high gain) For this reason, most MIC inputs or mixers are balanced and fitted with XLR connectors. Make sure your mixer has balanced line level inputs.

The balanced outputs of certain HD recording systems very often work with a certain cheap DAC which balances the signal electrically. Galvanically seperating transformers are hardly to be found in these devices.

Please note: An incorrectly soldered cable can cause any type of 'phase mutilation'.

4. Noise

As a rule, the noise level produced by OP amps is low enough to be ignored. Most mixers and especially effects devices produce far more noise than the DAC of a HD recording system.

Analog 8/4 Interface Features

The final version of the SoundPool Analog 8/4 is revision 2b. It features four/two high quality 16 bits stereo D/A converters with a new, complex output filter design. The frequency response is linear from 20 Hz to 20 kHz.

Outputs: standard line level, cinch connectors, asymmetrical. The separate power supplies for the digital and the analog section of the interface guarantee very low digital noise in the audio signal. The digital section is powerd by the internal power supply of the Falcon, the analog section uses the external 12 V power supply.

Power supply: External 12 V, 500-1000mA, - ring/+ tip
Analog output: Line Level, Cinch
Falcon Port: D-Sub, SoundPool format
SPDIF/FDI Port: D-Sub, SoundPool format
4MB STFM 1.44 FD- VELOCE+ 020 STE - 4MB STE 32MHz - STFM 16MHz - STM - MEGA ST - Falcon 030 CT60 - Atari 2600 - Atari 7800 - Gigafile - SD Floppy Emulator - PeST - HxC - CosmosEx - Ultrasatan - various clutter
