Product Information:
Delfina "Flipper Edition" is designed by Individual Computers in cooperation
with the developer team of Petsoff (Finland). We have licensed the
hardwaredesign, and have made many improvements. All known features of the
Delfina Plus remain including:
- DSP56002, 73,7Mhz, 96KByte memory, 12ns speed
- Codec: 16 bit, 48khz (other frequencies were played back by re-sampling)
- Outputs: Stereo-RCA
- Inputs: 2x Stereo-RCA, CD-input internally
- Interface: 16-Bit Zorro-II
- recording and playback Simultaneously (full duplex)
- AHI-drivers with an unlimited amount of virtual channels
If you think this is impressive see what we improved on !! Since re-sampling
may cause drawbacks in sound quality, the Delfina Flipper can playback other
standard frequencies (32khz and 44.1khz) without the need to re-sample, thus
having no loss in sound quality.
The original Delfina was delivered with a 66MHz DSP, overclocked to 73.7 MHz.
Since our revised version does not use the technique of re-sampling any more,
we decided to reduce the overclocking to a moderate degree to make the Delfina
work reliably in all enviroments. Despite the reduction to 67,73 MHz, more
calculation power is left for the user, because re-sampling is not necessary.
actual product may vary
Delfina Flipper is split into two cards. The "Delfina module" carries the
digital signal processor, memory and the analog inputs and outputs. This module
has two interfaces to the computer: One clock-port for the A1200, and a 26-pin
expansion port that is available on all our Zorro-cards. With these interfaces,
the module is ready to be used with nearly every classic Amiga!
There are a lot of sound-connectors: Three stereo-inputs with regular
sensitivity, and one stereo-input with increased sensitivity for a microphone.
The output is not using mini-stereo connectors as most other soundcards do, but
RCA connectors, because these allow a better sound quality.
The second board is the so-called "Flipper-interface". It uses technology known
from the Catweasel MK3 PCI/Flipper: The board can be used in a classic Amiga,
as well as in a PCI slot.
The Delfina-module is simply attached to the Flipper-interface. This expands
the Delfina with SP-DIF connectors that allow digital connection to HiFi
devices like DAT, Minidisc and CD-Recorders. Musicians will like the MIDI
connectors: One MIDI-in and one MIDI-out can be programmed independently of each
other.
The Zorro-interface has been re-designed from scratch. With the Delfina Flipper
we're showing for the first time that the slightly outdated Zorro-bus can do
much more than the engineers at Commodore have intended when they developed the
bus system: We simply doubled the performance. With usual values of about
5.2MB/second (theoretical value 7MB/second), it's possible to playback more AHI-
channels than any other soundcard did before. In full-duplex mode (record and
playback at the same time) this data rate can be split, but if you only record,
the known limits apply to the Delfina Flipper. Of course, this performances is
only reached with a 68020 or higher processor.
The clockport of the A1200 cannot reach the data performance of the Zorro-bus,
but it's still enough to playback several AHI channels, and of course to
playback MP3 files. A player-program that can output this popular audio-format
at best quality is included. That means that with the Delfina Flipper, the MP3
module is already included in the price!
Compared to the previous Delfina models, the price is surprisingly low: The
Delfina module at $ 149.95 is more than $ 175.00 cheaper than the cheapest
model of the predecessor. The Flipper-interface for $ 69.95 also allows using
the board with emulators like Amiga Forever or Amithlon, and of course with the
PPC-based successors of the classic-Amiga series such as Amiga One.
