The TT-1700DC power conditioner is designed to power high-end and hi-fi equipment. The main elements of the device are two balanced toroidal transformers 230 VAC/115 + 115 VAC, designed and developed by Audes, which isolate the device from the household network.

The two transformers are referred to as the main transformer and group 2 transformer and have nominal power ratings of 1500 VA and 200 VA. Such a design allows for the connection of low-power devices and devices with a switched-mode power supply (SMPS) to the separate group 2 transformer. The SMPS can cause distortions that can negatively affect analog devices if connected to the same power source. Devices connected to the group 1 sockets are isolated from devices connected to the group 2 sockets.

The power conditioner outlets are fully isolated from the mains. The output voltages are symmetrical to the artificial center tap, which is connected to the ground contacts of each outlet. The toroidal transformers inside the device have been designed to filter out interference from the mains through controlled leakage inductance and capacitance. The transformers have a very low output impedance, allowing the device to easily deliver large current surges up to the maximum power in each outlet while maintaining the nominal voltage.

When the power conditioner is switched on, the transformers are subjected to a high inrush current during the magnetization of the transformer core. Therefore, a soft start is implemented in the power conditioner. The power conditioner has a special resistor to limit the inrush current so that other electrical devices connected to the same power grid remain unaffected.

Despite the considerable nominal power of such transformers, the design of the power conditioner minimizes harmful electromagnetic radiation. Nevertheless, do not place the power conditioner near turntables and phono preamplifiers.

The power conditioner has an integrated DC blocker. The DC blocker protects the power conditioner from harmful effects of DC current present in the mains. This significantly reduces transformer hum due to a DC offset in the mains.

The power conditioner is protected by a thermal circuit breaker. As an additional precaution, both transformers have thermal protection that switches off a transformer if its temperature reaches 90 °C. Once the temperature drops to 75 °C, the device automatically reconnects to the mains.
