In all modes, taking pin 4 (Mute) to ground will disable amplifier and it will enter standby mode.
Although this module does not require forced cooling, it is recommended that it is housed in an
enclosure with some free airflow around the heatsink at the base. If the module is housed in a small
sealed enclosure the thermal protection may activate after some time. As with all electrical products
that generate heat, the life will be prolonged if the item is kept cool, therefore we recommend a small
fan if the item is being used continuously at high powers, or in bridge mode.
For further information, please see the manufacturer’s full instruction sheet downloadable from the
Enigma Shop product web page.
We sincerely hope you enjoy using our products.
