Power supply
The TCH-1 should be supplied from external regulated 9V DC power supply,
with capacity of 90 mA or more. It is recommended to use separated source e.g. G LAB
PB-1 in order to avoid ground loop. Before connecting please check if the connector’s
polarization is CTR – (center negative).
The TCH-1 is protected against opposite polarity. If this protection activates it is needed
to disconnect the power supply and wait few minutes before reactivation of the device.
ATTENTION: Damages caused by improper power supply causes loss of
the warranty.
