Safety instructions CAUTION! Possible hearing damage The device can produce volume levels that may cause temporary or permanent hearing impairment. Over an extended period of time, even levels that seem to be uncritical can cause hearing damage. Decrease the volume level immediately if you experience ringing in your ears or hearing impairment.
Page 11
Unplug the device before electrical storms occur and when it is unused for long periods of time to reduce the risk of electric shock or fire. TSA 4-700, TSA 1400, TSA 2200, TSA 4000, TSA 4-300, TSA 4-1300...

Safety instructions NOTICE! Magnetic fields The device generates strong magnetic fields that can interfere with the function of poorly shielded devices. The strongest magnetic fields are directly above and below the power amplifier. Therefore, never place sensitive devices such as pre- amplifiers, radio transmission systems, or tape decks directly above or below the power amplifier.
Installation and starting up Installation and starting up NOTICE! Possible staining The plasticiser contained in the rubber feet of this product may possibly react with the coating of your parquet, linoleum, laminate or PVC floor and after some time cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the floor, but use felt-pad floor protectors or a carpet.

In addition to the conduc‐ tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers the signal, but phase-shifted by 180°. TSA 4-700, TSA 1400, TSA 2200, TSA 4000, TSA 4-300, TSA 4-1300...

Plug and connection assignment Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized.
