    RIEF DESCRIPTION CTK38 is composed by a VHF transmitter (CST38) and a power supply (PSP910). The CST38 transmitter has been especially designed to allow best usage of MicroEar’s family “in-ear receivers” and many modulation parameters such as deviation, level/frequency curve, compression factor has been optimized. Therefore CST38 assures maximum performances of MicroEar both as sound quality and as audio level (in any case limited because of the very small size of receiver).
