The board is controlled by software for a Windows PC. The parallel cable must be the standard type used for hooking up a printer to a PC: one end is a DB-25 connector andthe other is a 36 pin Centronics connector. Banana connections are provided for V DD, ground, and am- plifier outputs. Amplifier outputs are also routed to a stereo headphone jack. RCA connections are provided for amplifier inputs, loop in, loop out, and microphone out. Mono mini- plug connectors are provided for microphone inputs. If required, microphones can be biased using the resistors R MIC1 and RMIC2. This layout is set up to allow the use of the internal tone- control circuitry or the external loop. The jumper next to each C LIN capacitor controls which route the signal should take. DS100014-31 www.national.com 16 |
