Which hardware configuration do you recommend to take full advantage of the card?
Answer 1:
Systemrequirements:
• Windows XP SP2, XP X64, Vista oder Vista X64
• MAC OS 10.4 oder higher
• 256 MB RAM
• 1,4 GHz CPU oder higher (Windows)
• Apple Computer with Intel Processors
• 1 freie USB 2.0 Port
• CD/DVD – ROM for Driver and Softwareinstallation
Systememrecommendation:
• Windows XP mit Service Pack 2
• 512 MB RAM
• 2 GHz CPU
Is it possible to use the DMX 6Fire USB without a power supply?
Answer 2:
No, this is not possible. You have to use the Power Supply (12V / 1500mA).
How much Power is needed?
Answer 3:
Max. 1000 mA.
Will the DMX 6Fire USB system work on USB 1.1 ports?
Answer 4:
No.
Can I send AC3 or DTS to an external decoder when playing DVDs or Movies?
Answer 5:
Yes.
What is the DMX 6fire USB signal to noise ratio (SNR) and up to which samplerate can a signal be converted?
Answer 6:
• 24 Bit / 192 kHz A/D converter 114 dB (A) SNR* (In 1/2); typical: 111db (A) SNR
• 24 Bit / 192 kHz A/D converter 105 dB (A) SNR* (In 3/4); typical: 101db (A) SNR
• 24 Bit / 192 kHz D/A converter 114 dB (A) SNR* (Out 1-6); typical: 111db (A) SNR
* technical Data from the AD/DA Chip
What can I do if the control panel can not access the hardware?
Answer 7:
The Controlpanel needs the driver to communicate with the Hardware. Please verify the correct Installation of the driver in the Device Manager, „ Sound, Video- and Gamecontrollers”.
What is the impedance of the In- and Outputs?
Answer 8:
Line IN 1/2: 0,5 V – 2,5 V
Line IN 3/4: 2,5 V
Instrument IN: 100 mV – 3 V
XLR MIC: 10 mV (without PAD) – 1,6 V (with PAD)
Consumer MIC: 15 mV – 1,8 V
Line OUT 1-6: 2,5 V
Why is it not possible to hear Midi sounds?
Answer 9:
Because the DMX 6fire is a pure I/O-card for HD-recording and software
synthesizers and is not able to generate Midi
sounds from its hardware
on its own. To play Midi
sounds you'll need to use a virtual synthesizer (softsynth)
or hook-up a Midi
hardware device to the Midi-Out port.
Can I uplink to other DMX 6fire devices?
Answer 10:
No .
Is it possible to use Steinbergs Cubase VST together with the DMX 6fire USB?
Answer 11
Yes. Because the DMX 6fire USB is equipped with the latest ASIO 2.0 Drivers, very low Latency is possible.
What is the Assignment on the analog outs for Dolby 5.1?
Answer 12:
Line Out 1/2 = Front Left / Front Right
Line Out 3/4 = Center / Subwoofer
Line Out 5/6 = Rear Left / Rear Right
What level can be applied to the analog input and what it the typical SNR of the Inputs?
Answer 13:
The analog inputs are build for the Line-level-signals (up to 2,5 Vrms) and the typical SNR are 111db.
What latencies can I achieve in ASIO mode?
Answer 14:
Latencies of less than 4ms are possible on modern, well-configured
systems
What impedances and which output voltage do I need for the best performance of the phono input?
Answer 15:
Input-Impedance: 47 kΩ
Input-capacitance: 100 pF
Why is my S/PDIF IN not audible when I set the samplerate higher than 96 kHz?
Answer 16:
Up to 96 kHz are only for the S/PDIF I/O’s available. Higher samplerates are only for the analog inputs.
Why I don’t hear any noise after switching from Multi Channel to Multi Device under Windows XP (32-bits and 64-bits)?
Answer 17:
Thank Microsoft! All settings under “Start ->control panel -> sounds” will be lost after switching from Multi Channel to Multi Device (or vice versa) and the DMX 6Fire USB is no longer the standard device. Please verify the configuration each time you change the driver.
Which channels are supported for the Surround Expander function??
Answer 18:
The Suround Expander only works with Line 1/2 and Waveplay 1/2.
Which samplerate has a Dolby- or DTS Stream?
Answer 19:
A standard Dolby- or DTS Stream has a samplerate of 48 kHz. All normal DVD players are playing with 48 kHz. Please change the samplerate to 48 kHz while watching DVDs.
Which record player pick-ups are supported by the DMX 6Fire USB?
Answer 20:
Only Moving Magnet pick-ups are compatible.
