Description
A versatile MC transformer
The ST-7 is a compact moving coil step-up transformer in a solid housing on four rubber feet, which help reduce unwanted vibration. Its sandwich winding structure is designed to improve high frequency response, for a clear and open sound across the frequency range.
High-quality internal wiring and gold-plated terminals are used for signal transmission, and the dual-mono design, with individual shielding for each channel, improves imaging and reduces environmental interference. Ortofon publishes a gain of 24 dB and a cartridge impedance range of 2 Ω ~ 60 Ω.

To Keep your equipment safe these are some best practices to note. Please be advised that this is only to reduce the risk of misuse and is not an exhaustive list.
Speakers
- Speaker terminals are marked red and black, ensure your amplifier to the speakers are wired on the same colours
- Ensure no loose speaker wire from the red touches a loose wire from the black as this will lead to a short circuit and damage either the speaker, the amplifier or both.
- Not all speakers are designed to play at max volume, kindly consider the pairing of your amplifier and speakers
- Speaker cabinets cannot be replaced please handle with care.
AV & Stereo Amplifiers
- If your amplifier has HDMI ports, ensure all devices are off before plugging in the HDMI cable
- Turn off the amplifier before swoping out or adding speaker cable
- Amplifiers generate heat, place them in a well ventilated space. if possible avoid having anything on top of the unit.
- adding a surge protector can assist with power dips which are likely to damage your devices. Isotek and Furman are industry standard.
- Dusty environments can sometimes lead to accumulation of dust in the electronic components that might affect heat regulation
