DMAN 2044 drivers behave like four stereo WAV devices:
Audio Connectors Windows Device Name
IN1 / IN2 “DMAN2044 1/2 Record”
IN3 / IN4 “DMAN2044 3/4 Record”
OUT1 / OUT2 “DMAN2044 1/2 Playback”
OUT3 / OUT4 “DMAN2044 3/4 Playback”
Although this may appear at first to impose a severe restriction on how
the card can be used, it actually does not. Most of the more-advanced
audio applications allow the user to assign audio tracks to more than one
of these devices at a time, allowing complete simultaneous use of all
audio ports!
Hardware Mixer Operation
The DMAN 2044 hardware mixer controls the playback levels of all 4
WAV audio streams, the levels of the input monitors, and the routing of
the input monitors to output channels. Each hardware input (IN1, IN2,
IN3, IN4) is mixed and routed as shown below (the figure below depicts
just one of four circuits in the hardware input mixer):
IN1 Mixer Block Diagram
Notice that not only does the audio from each input go to your software
application for recording, but it is also monitored at the output of your
choice. The monitoring level and destination are both software-pro-
grammable.
NOTE: There are no “recording level” controls for the DMAN 2044
inputs. In order to obtain the maximum possible dynamic range and
lowest noise, the inputs are always run at full-scale. The external
audio source driving each input should be adjusted at the external
audio source for optimal recording levels.
Each hardware output (OUT1, OUT2, OUT3, OUT4) receives a mix of
WAV playback audio plus monitor audio. The figure below depicts just
one of four circuits in the hardware output mixer:

- Each dman 2044 audio input channel may be configured to accept either 10 db or 4 db signal levels this configuration is accomplished by installing or removing a hardware jumper for each channel an installed jumper factory default selects 10 db a removed jumper selects 4 db for best signal to noise performance use the 4 db setting and set your audio source louder than you would if using the 10 db set ting 9

- Before pnp properly configuring a pc compatible system was no small task usually when new devices were added to the system the hardware was manually configured with jumper blocks and dip switches and there were configuration conflicts that caused the computer to work erratically or not at all users typically resolved configuration conflicts by consulting complicated documentation provided with the each inter face card contacting the supplier s technical support group consulting a friend or giving up in disgust even trained engineers found the pc card configuration process unreliable and frustrating as the current generation isa expansion cards were introduced including multi func tion versions with wavetable music synthesis hi fidelity audio mpeg audio video fax modem capabilities more systems resources were required than ever before causing even more system resource conflicts 28
- In 1993 the first pc pnp specification was proposed as a solution to com mon resource conflicts pnp defines a means for the computer to com municate with its various installed devices and resolve any potential resource conflicts in theory with a working pnp system jumpers and dip switches are a thing of the past and compliant hardware is config ured automatically or with little user intervention pnp works with exist ing bus architectures and is widely supported by the industry to gain 28 28
