007- I just got a Phasor Sound Card and now I need some
info. What are the 4 DIP switches used for? What are the
2 POTs used for? And, where can I get programming
information?
The Phasor is a great sound card. Offers you 12 sound channels (using all
sorts of wave-form patterns and effects, simular to FM-synthesis in IBMs), 4
white noise generators (synthesized drums, etc) and a 1-voice synthesized speech
channel, expandable to 2 speech channels. Has a 4 watt amplifier that can drive
stereo speakers (left & right). It's compatible with most older sound cards,
like the Mockingboard, ALF, SMS and Echo+. Few programs ever supported it, let
alone many programs out there that sup
ported the older cards. It did, however, come with some decent software that
showed off the card's features and let you experiment with it a bit.
The four DIP switches control emulation modes and standard Apple ][
internal speaker sound-level (only if you disconnect internal speaker and have
old speaker toggling sent to Phasor). Switches #1 and #2 are for emulations.
Switches #3 and #4 control your old internal speaker sounds, again, *if* you
have speaker disconnected and that pin location on motherboard connected to
Phasor.
You can set Low, Medium and High volume with three different DIP positions.
This doesn't affect Phasor music/sound however. To do that, you must turn those
two pots you asked about. Each controls either the left or right stereo channel.
Turning them clock-wise increases volume, and you probably don't want this too
high up, or sound gets distorted! Put both on an equal setting, unless you want
one channel louder/softer than the other.
Phasor DIP switch emulation modes:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Native Phasor mode: 1: closed, 2: closed
Mockingboard mode: 1: opened, 2: closed
Echo+ mode: 1: opened, 2: opened
(Never got the Echo+ mode to work!)
