UNPACKING INSTRUCTION
CAUTION! Carefully unpack the box upon receipt. Check the contents to ensure that all parts are present and have been
received in good condition. Notify the shipper immediately and retain packaging material if any parts appear damaged from
shipping or the package itself shows signs of mishandling. Save the package and all packaging materials. If the product must be
returned, it is important that the product is returned in the original factory box and packaging.
If the device has been exposed to drastic temperature fluctuation (e.g. after transportation), do not switch it on immediately. The
arising condensation water might damage your device. Leave the device switched off until it has reached room temperature.
OVERVIEW
1. NL-4 CONNECTOR
Input for connecting to amplifier output with NL-4 cable.
2. SCREW TERMINALS
Screw terminal input (from amplifier) and output (additional speaker looping) for connecting by
using speaker wire.
NL-4 CONNECTION
This speaker allows for connection by NL-4 cable via the NL-4 input connector.
Use a suitable NL-4 type cable of good quality to ensure function.
SCREW TERMINALS
For optimum performance it's important to use cables specifically designed for speaker use. Do not use shielded "guitar" signal
cables for connection to these speakers.
Selection of the appropriate wire gauge is important for system operation. A cable that is too light will result in amplifier power
being wasted due to the series resistance of the cable. In addition, loss of low-frequency performance may be experienced due
to a degraded damping factor.
Looping speakers
Running too many speakers from a single amplifier channel may result in damage to the amplifier and/or in degraded audio
performance. To calculate the combined impedance of multiple identical speakers in parallel, please use the formula below:
Keep in mind that two 8 Ohm parallel linked speakers will equal a 4 Ohm load.
Refer to your power amplifiers owner's manual, for information on minimum recommended load impedance.
