mandatory to perform any plugging or unplugging of microphone cables with the phantom power turned off. Also make sure, that the phantom power is turned off when utilizing microphones that are not meant to be operated with phantom power. The voltage that is present on pin 2 and pin 3 of the XLR-connector could lead to severe damages on the microphones. When in doubt, please consult the owner’s manual of the questionable microphone or contact your dealer before you perform any connections.

17. input sensitivity switch (IN 1)

Setting this switch to its “MIC”-position lets you connect a low-impedance dynamic microphone to the IN 1, while in LINE-setting a high-level sound source can be played via the IN 4.

18. input “IN 1"

This balanced input lets you either connect a low-impedance dynamic microphone (30 - 600 ohms) or a high-level sound source (e. g. AM/FM tuner, cassette deck, CD-player, etc.). The connector is carried out as 1/4" phone jack. To adjust the input sensitivity, please use the corresponding switch (17). The input features the “Voice Priority” function which overrides all other input signals once a microphone message is send. If you want to have this function disabled, please contact a DYNACORD SERVICE CENTER.

19. mains cord connector

This connector is meant for the connection of the supplied mains cord.

20. binding posts for the DC battery supply

These two binding posts allow the connection of an external 24 V DC power supply ( e. g. a 24 V DC battery). In this way continuous operation of the amplifier is maintained even during a power outage, since it is automatically switched to the DC power source.

NOTES

The amplifier is not capable of recharging the connected battery. Thus, it is recommended to have a suitable device at hand.

When the amplifier is operated on the DC power source, the nominal power handling capacity drops by approximately 20 %.
