Microphone preamplifier
PRE-01
The microphone preamplifier PRE-01 has been designed to match Audiomatica’s microphones MIC-01, MIC-02 andMIC-03. It is particularly useful when the microphone has to be operated far from the analyzer or when weighted measurements are needed. PRE-01 powers the microphone connected to its input with an 8.2V phantom supplyand adds a selectable weighting filter (A or B or C); also available there is a 20 dB gain stage

Microphones
MIC-01, MIC-02 and MIC-03 are low cost precision condenser electret microphones perfectly suited for laboratory and on-field acoustical measurements. They have identical performances but differ for their physical size; MIC-01 is preferable for fixed laboratory installations while MIC-02 is highly manageable due to its short length; MIC-03 is the best where space saving is a must. Their frequency response is individually tested against specifications and the sensitivity value is supplied. MIC-01 & MIC-02 & MIC-03 can be directly connected to your CLIO system's input.

Amplifier, Switch and Test Box
CLIOQC Model V
The QCBOX Model 5 is a non-conventional unit designed to fulfil actual and future needs of an electro-acoustical analyzer like the CLIO system. It is USB linked to a PC and can be configured, with dedicated software controls, to assist frequency response and impedance measurements or to perform DC measurements. Using it for frequency response measurements acts as 50W power amplifier to drive the speaker or network under test while routing one-of-four inputs to the analyzer as well the current sensing output. The four inputs are able to provide a phantom power supply both for Audiomatica or general purpose microphones (0-24 V range, software controlled). Impedance measurements can be done either switching the D.U.T.’s load across the analyzer’s input or using a dedicated output, ISENSE, thus allowing impedance measurements in constant voltage mode as well voice coil current distortion analysis. An internal ADC measures the DC current into the voice coil. Thanks to an internal software controlled voltage generator the speaker can be driven with a superimposed DC voltage (±20V), allowing for measurements of large signal parameters. Two ADC converters with a ±2.5 V and ±5 V are available at inputs 3 and 4 to measure the displacement with a laser sensor or any other DC signal. A dedicated digital input handles an external foot pedal switch (or TTL signal) to be connected and triggers QC operations. A 6 bit output – 5 bit input TTL digital port is available to interface the QCBOX and driving software with external hardware (like turntables for example).The QCBOX Model 5 finds use both in laboratory for R&D applications and in production lines setups.

Calibration Services
Your CLIO hardware can be furnished with (or be submitted for) a SIT Certificate of Calibration. This document, produced by a laboratory accredited by the Italian Calibration Service, reports measurement data of the primary quantities generated and analyzed by the instrument (AC Voltages) traceable to National and International Standards. This document is usually requested for ISO compliance.
