- 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
