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!)
