The TT-1700DC power conditioner is designed to supply electrical power to High-End and Hi-Fi AV equipment. The main elements of the power conditioner are two balancing toroidal transformers 230 VAC/115 + 115 VAC designed and developed by Audes, which isolate the equipment from the domestic network. The two transformers are referred to as the main transformer and the Group 2 transformer, which have the power ratings of 1500 V∙A and 200 V∙A respectively. Such design allows to connect low-power devices with switched-mode power supply (SMPS) to the separate Group 2 transformer. The SMPS can introduce distortions, which may adversely affect analogue devices, when connected to the same power source. Devices connected to the Group 1 outlets are isolated from devices connected to the Group 2 outlets.

The toroidal transformers inside the unit were designed to filter noise from the mains utilising controlled leakage inductance and capacitance. An integrated DC blocker protects the unit from harmful influence of direct current present in the mains. This feature significantly reduces transformer hum caused by DC offset, ensuring quieter operation. The outlet sockets of the TT-1700DC are fully isolated from the mains. The output voltages are symmetrical with respect to the artificial centre tap that is connected to the earth contacts of each socket.

When the power conditioner is switched on the main transformer is subject to a high inrush current during magnetisation of the transformer core. Due to this a soft start is implemented into the power conditioner. The power conditioner has a special ballast resistor to limit the current surge, so that other electrical equipment, which is connected to the same electrical network, remains unaffected.

The power conditioner is protected by a thermal circuit breaker. As an additional precaution, both transformers have thermal protection, which switches a transformer off if the temperature of the transformer reaches 90 °C. Once the temperature drops to 75 °C the device will reconnect to the electrical network automatically.
