T-100 Phono Amplifier Description The CT100 is a two-channel phono preamplifier module with a very accurate RIAA equalisation and many features. It is constructed with the best semiconductors available and non-inductive, low noise, SMD metal film resistors. The circuit is designed to accept both moving coil (MC) and moving magnet (MM) transducers / cartridges directly in order to eliminate the need for an external MC step-up transformer or amplifier. MC or MM input loading and input nominal level values are easy to select with high accuracy using DIP-switches. The DACT CT100 is ideal for the most demanding applications requiring accurate RIAA equalisation, very low noise, extremely low distortion and superior sonic performance. The CT100 is a pre-assembled PCB ready for building into an enclosure or even better into your turntable (shorter signal cables). The high output voltage from the CT100 gives it an equivalent output to other signal sources like CD-players. Features Compact design. Dual-mono. Very low noise. Balanced output option. Non-inductive low noise SMD metal film resistors. Input accepts moving coil or moving magnet (MC or MM) cartridges directly without step-up transformer. Input loading 10 Ohm to 47 kOhm for MC or MM selectable in 21 steps. Input nominal levels 0.1 mV to 10 mV selectable in 34 steps. High output drive. Balanced: 28V. Unbalanced: 14V. High accuracy RIAA equalisation with 0.05 dB tolerance. Additional time constants of 3.18 uS and / or 7950 uS are selectable. Total harmonic distortion 0.0003%. Low output impedance - drives long signal cables. High output current capability - drives even high impedance headphones. Two-stage dual-supply voltage regulator onboard for each channel. Separate DC supply input for each channel (dual mono). High-end matching power supply CT102 available. Typical Applications High performance RIAA pre-amplifier for MC and MM cartridges. High performance RIAA headphone amplifier. Upgrading Hi-fi equipment. Reference RIAA pre-amplifier. Test equipment RIAA pre-amplifier.
