>>>>>>>>>> CAUTION <<<<<<<<<<
PLEASE READ BEFORE CONNECTING ELECTRONIC DEVICES TO YOUR JD7!
Caution must be used when connecting electronic equipment to the JD7. The JD7 bridges all electronic
equipment connected to it so faulty wiring or incorrect grounding of any of the equipment may cause a
shock hazard to be present and/or damage to the JD7 or other connected equipment. Because grounding
schemes differ between manufacturers, it is important to check for correct polarity, in particular with older
amplifiers using 2-prong ungrounded A/C cords. If the polarity is reversed on an ungrounded amplifier
there may be a potential of 120V present between the amp chassis and ground. Radial Engineering takes
no responsibility for this or how the JD7 is connected or used. It is the users full responsibility to ensure that
proper electrical polarity is maintained on all equipment connected to the JD7 and that proper building
electrical codes have been followed wherever the JD7 is being used.
To reduce opportunity for shock hazard or damage to the JD7 or connected equipment, plug the ¼”
connectors into the amplifiers first and then to the JD7. This is especially important when using old
amplifiers that do not have 3-prong plugs as the possibility exists to touch the chassis ground with the
connector plug tip when the plug is inserted into the jack.
Cautions for amplifiers with ungrounded 2-prong A/C cords: Before connecting any input to an
ungrounded amplifier, power the amp up and listen to the residual hum. If the amp has a two-position
ground polarity reverse switch, set the switch in the position that produces the least residual hum from the
speakers. If there is no polarity switch, reverse the A/C plug at the outlet to find the least residual hum.
To ensure an ungrounded amplifier does not present a shock hazard: Test for voltage potential by
connecting a voltmeter between the amplifier chassis and the JD7 chassis. If voltage is present, reverse
the amplifier’s A/C supply polarity and test again.
Note that due to this potential problem, damage to the JD7 or other connected equipment caused by
improper A/C polarity is not covered under warranty.
