As the power consumption of keyboards becomes greater as their specifications and power increases, the prospect of having a portable multi-power adaptor becomes less practical. Our major concern is safety in the classroom, and it is usually more sensible to have well-made fused multiblocks with individual adaptors, than a powerful single distribution unit.

   In this section, we show a couple of good quality extension multiblocks (sometimes called distribution boards) which can be used to power up several musical instruments from one wall socket. We also show here DC power cables for the MPA series of multi-adaptors.
