2.1 THE PB-4281 PC BOARD AND SC-01 SIGNAL CONDITIONER The PB-4281 PC board and SC-01 Signal Conditioner form a high precision two channel A/D-D/A audio front-end for your IBM or compatible PC. The PB-4281 PC board is housed in a standard PCI slot inside your computer and performs precise 18-bit digitizing of the signals to be analyzed. The SC-01 Signal Conditioner is software controlled via an RS-232 serial link; it is equipped with instrument grade input and output analog circuitry with an exceptionally wide range of output attenuation and input gain that allows an easy interface to the outside world; the input and output loop-back capability with the internal ultra stable voltage reference permits a simple and precise calibration of the whole instrument; the two input channels can be controlled separately or as a single balanced one. A switchable phantom supply lets you directly connect an Audiomatica MIC-01 or MIC- 02 microphone to any of the SC-01 inputs. It is also possible to superimpose a DC voltage to the generated AC signal. 2.1.1 COMBINED TECHNICAL SPECIFICATIONS GENERATOR Two channels 18 Bit sigma-delta D/A Converter Frequency range: 1Hz-22kHz Frequency accuracy: >0.01% Frequency resolution: 0.01 Hz Output impedance: 150 Ohm Max output level (Sine):12dBu (3.1 V RMS) Output DC (Ch. A): ±2.5V Attenuation: 0.1 dB steps to full mute THD+Noise (Sine): 0.01% ANALYZER Two channels 18 bit sigma-delta A/D Converter Input range: +40 ÷ -40dBV Max input acceptance: +40dBV (283Vpp) Input impedance: 64 kOhm (5.6 kOhm mic) Phantom power supply: 8.2V PC SYSTEM RESOURCES One free IRQ One free RS-232 port MISCELLANEOUS Sampling frequency: 48kHz÷8kHz Card type: 12cm.

2.2 THE MIC-01 MICROPHONE The MIC-01 microphone is an electret measuring microphone that is particularly well suited to being used in conjunction with the other components of the CLIO system. It is furnished with its own stand adaptor and a calibration chart reporting the individually measured sensitivity, all fitted in an elegant case. Its long and thin shape renders it ideal for anechoic measurements. Because its frequency response is very flat over the entire audio band, no particular correction is usually needed. 2.2.1 THE MIC-02 MICROPHONE The MIC-02 microphone is functionally identical to MIC-01. It differs only in the fact that its length is 12 cm instead 25 cm. The MIC-02 is more practical to handle and to work with, and is ideal for measurements in a reverberant environment. 2.2.2 TECHNICAL SPECIFICATIONS MIC-01 Type: Accuracy: Maximum level: Dimensions: Accessories: MIC-02: Condenser electret ±1 dB, 20 Hz to 10 kHz ±2 dB, 10 kHz to 20 kHz (direct field) 130 dB SPL 8 mm diameter, 25 cm long wooden case, 2.7 m cable, stand adaptor Same as MIC-01, but 12 cm long.
