Tuning stages The CT-10 employs a Phased Locked Loop digital front end. Our goal is to provide maximum audio performance when tuned to strong stations, without sacrificing the ability to receive weaker and more distant ones. Circuit layout, critical in all audio applications, is particularly important in radio frequency designs. The Class? CT-10 circuit components have been laid out by hand, by an experienced design team, to assure the best possible performance from the tuning stages. No computer-routing program can compete with experienced designers in this essential task.
Balanced circuitry As with the tuning stages, all audio circuits inside the CT-10 benefit from high-quality circuit board materials and component layout by experienced designers. Component parts are selected for sound quality and reliability. As with other Class? designs, the analog output stage features balanced circuitry. When properly implemented, balanced circuits and interconnections can reject noise and distortion, which would otherwise degrade audio signals. Class? takes care when implementing balanced circuits to derive the full benefit from this more costly topology. In the end, we achieve the sweet, dynamic and open sound quality that has become a hallmark of Class? performance.
Interconnection standards The CT-10 offers both single-ended and balanced line-level outputs for use in systems equipped with either interconnection standard. The chassis is fitted with professional-grade XLR as well as RCA-type phono connectors.
Special features The CT-10 features US-system Radio Data System (RDS) tuning. For stations broadcasting RDS information, the unit will display PS (station call letters), CT (clock/calendar information) and PT (program-type, such as “Classical,” “Talk,” etc).
The CT-10 is equally at home in high-end stereo, home theater and whole-house entertainment systems. It offers convenience features such as IR remote control, rear panel IR in and out, RS-232 control, DC trigger control, discrete commands for on/off and all tuner functions, direct frequency access tuning and memory for dozens of AM and FM preset stations.
Whether integrated with a third-party control system or placed on a shelf and operated by infrared remote control, the CT-10 is an elegant addition to any high-performance music system. The chassis is hand-crafted in the Class? tradition with a two-toned billet-aluminum finish. As with all Class? components, the CT-10 is designed to deliver years of enjoyment and complete satisfaction.
