Which hardware configuration do you recommend, and how high must the data
transfer rate of the hard drive be to take full advantage of the card?
Answer 1:
The minimum system requirements are:
System requirements PC
System requirements MAC
System recommendation PC
System recommendation MAC
The required data transfer rate can be calculated as follows:
((((Number of tracks X resolution in bits X sampling
rate in Hz) / 8) / 1024) / 1024) = MB/s
Thus 4 tracks at 32 bits / 96 kHz require a hard drive and controller
that can handle a data transfer rate of 1.5 MB/s.
Regarding the 32 bits in the formula (rather than 24 bits): All of the
cards drivers are capable of forwarding 24-bit audio data to the recording
software as 32-bit data.
This feature reduces the CPU load substantially, as 24-bit data doesn't need to
be "stacked" to pass through the 32-bit wide bus, as in the
conventional "packed-byte" process.
When selecting components for a hard-drive recording system based on the
AudioSystem PHASE 28, we recommend the following hard-drive controllers in
descending order:
Please note that additional PCI cards can affect the performance of the
PCI bus and thus the operation of the PHASE 28 system. This effect is naturally
more pronounced at 24-bit / 192 kHz
than at lower settings.
Which operating systems are supported? What additional support is
planned for the future?
Answer 2:
The card supports driver models as follows :
Does the PHASE 28 system support Suspend to Disk“ or „Standby“?
Answer 3:
Yes.
Is it possible to play and/or record analogue and digital signals with
different sample rates simultaneously?
Answer 4:
Yes, with the exception of ASIO or WDM kernel streaming applications.
Does the MIDI port need an extra interrupt?
Answer 5:
No, an additional interrupt is not required.
Can I use the PHASE 28 system as a mixer?
Answer 6:
Only if you are using a recording software with e. g. ASIO-support (e.g.
Steinberg Nuendo) . The PHASE 28 system has no mixer or EQ.
How 'clean' is the synchronisation by recording and playback in general?
Answer 7:
The synchronization of the channels is absolutely sample-synchronous.
Is it possible to add an XG-Wavetable module to the card?
Answer 8:
No.
Can the card be cascaded with additional PCI audio systems?
Answer 9:
Yes, the system can be synchronised to additional systems with
EWS-Connect facility (EWS88 MT/, MIC, PHASE 88,…) Up to four systems be linked
in one PC.
Why is the card red?
Answer 10:
Because the red colour increases the signal-noise ratio and decreases
the latency ….I’m just kidding ;o)
it just looks nice.
How large is the control parameter for the Input signal on the PHASE 28
system?
Answer 11:
The inputs are designed for 2,2 Volt RMS @ 1 kHz. The gain controls on
the slot-bracket can decrease or amplify the input signal (-19 dB to +12 dB). In addition the input A/D-converter
do also have a gain setting which can be controlled within the ControlPanel (
Input Gain ).
Can an internal CD audio output from a CD-ROM drive be connected?
Answer 12:
No.
How many resources are used after installation in my system?
Answer 13:
The PHASE 28 system only requires one interrupt and a variety of memory
blocks.
How good is the signal to noise ratio?
Answer 14:
A/D measured : 100 dB (A),
24 Bit/192 kHz A/D converter
with 102 dB (A)
D/A measured: 105 dB (A),
24 Bit/192 kHz A/D converter
with 106 dB (A)
Can I use the GigaSampler/Studio at the same time that I use an audio
sequencer program like Cubase VST or Emagic Logic?
Answer 15:
Yes.. Within the ASIO ControlPanel you can set up an ASIO/GSIF
multi-client mode.
Do the drivers work with the software CoolEditPro?
Answer 16:
Yes.
What is the best CoreAudio latency on MAC OS X?
Answer 17:
Depending on your system performance less than 4 ms are possible.
Are there any special points to consider by the
installation under Windows 2000 or XP?
Answer 18:
It is strongly recommended that you log on these systems as
"Administrator". Otherwise it may be that speaker configuration can
not be changed.
How much sensitivity do the analogue In and Outputs have?
Answer 19:
|
Analogue In |
2,2 Vrms @
1 kHz (Gain -19 dB up to +12 dB), 10 kOhm |
|
Analogue Out |
2,2 Vrms @
1 kHz, 220 Ohm |
The recorded Signal is distorted, what went wrong?
Answer 20:
In most cases you can solve this problem by increasing the buffer size
within the ASIO control panel.
Is a ASIO support for MAC OS X planed?
Answer 21:
Yes, as soon Steinberg includes such a support to their OS X products we
plan to prepare those drivers.
Why can't I hear any Midi sounds?
Answer 22:
Because the PHASE 28 system
is a pure I/O-card for HD-recording and software synthesizers arenīt
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.
Why can't I hear any Midi sounds?
Answer 23:
This can happen if you switch the card's synchronisation to
"External" but no external device has been connected. In this case
please connect the external device, switch back to "Internal" and
then back to "External"
