2. Keep all information and instructions in a safe place.
3. Follow the instructions.
4. Observe all safety warnings. Never remove safety warnings or other information from the equipment.
5. Use the equipment only in the intended manner and for the intended purpose.
6. Use only sufficiently stable and compatible stands and/or mounts (for fixed installations). Make cer-
tain that wall mounts are properly installed and secured. Make certain that the equipment is installed
securely and cannot fall down.
7. During installation, observe the applicable safety regulations for your country.
8. Never install and operate the equipment near radiators, heat registers, ovens or other sources of heat.
Make certain that the equipment is always installed so that is cooled sufficiently and cannot overheat.
9. Never place sources of ignition, e.g., burning candles, on the equipment.
10. Ventilation slits must not be blocked.
11. Do not use this equipment in the immediate vicinity of water (does not apply to special outdoor
equipment - in this case, observe the special instructions noted below. Do not expose this equipment
to flammable materials, fluids or gases.
12. Make certain that dripping or splashed water cannot enter the equipment. Do not place containers
filled with liquids, such as vases or drinking vessels, on the equipment.
13. Make certain that objects cannot fall into the device.
14. Use this equipment only with the accessories recommended and intended by the manufacturer.
15. Open the device for changing the battery, do not modify this equipment.
16. After connecting the equipment, check all cables in order to prevent damage or accidents, e.g., due
to tripping hazards.
17. During transport, make certain that the equipment cannot fall down and possibly cause property
damage and personal injuries.
18. If your equipment is no longer functioning properly, if fluids or objects have gotten inside the equip-
ment or if it has been damaged in another way, switch it off immediately and unplug it from the
mains outlet (if it is a powered device). This equipment may only be repaired by authorized, qualified
personnel.
19. Clean the equipment using a dry cloth.
20. Comply with all applicable disposal laws in your country. During disposal of packaging, please sep-
arate plastic and paper/cardboard.
21. Plastic bags must be kept out of reach of children.
22. If the equipment has been exposed to strong fluctuations in temperature (for example, after trans-
port), do not switch it on immediately. Moisture and condensation could damage the equipment. Do
not switch on the equipment until it has reached room temperature.
23. Do not step on the power cord. Make certain that the power cable does not become kinked, especially
at the mains outlet and/or power adapter and the equipment connector.
24. When connecting the equipment, make certain that the power cord or power adapter is always freely
accessible. Always disconnect the equipment from the power supply if the equipment is not in use
or if you want to clean the equipment. Always unplug the power cord and power adapter from the
power outlet at the plug or adapter and not by pulling on the cord. Never touch the power cord and
power adapter with wet hands.
25. To disconnect the equipment from the power mains completely, unplug the power cord or power
adapter from the power outlet.
26. Unplug the power cord and power adapter from the power outlet if there is a risk of a lightning strike
or before extended periods of disuse.
CAUTION:
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
There are no user serviceable parts inside. Have repairs carried out only by qualified service personnel.
CAUTION – HIGH VOLUME LEVELS WITH AUDIO PRODUCTS!
This equipment is intended for professional use. Therefore, commercial use of this equipment is subject
to the respectively applicable national accident prevention rules and regulations. As a manufacturer, Adam
Hall is obligated to notify you formally about the existence of potential health risks. Hearing damage due to
high volume and prolonged exposure: When in use, this product is capable of producing high sound-pres-
sure levels (SPL) that can lead to irreversible hearing damage in performers, employees, and audience
members. For this reason, avoid prolonged exposure to volumes in excess of 90 dB.

SCOPE OF APPLICATION
Balanced or unbalanced isn’t the question here. BALUN stands for Balanced-Unbalanced. Thanks to the
stereo TRS jacks used in the PLI05, it can cope with both balanced and unbalanced signals. The PLI05
is so to say the PLI02’s little sister. Both boxes can be used to convert balanced to unbalanced and both
use so called line isolating transformers to realize a galvanic separation. They are connected between
mains powered devices to reliably prevent ground loop hum. The PLI02 was designed for use with XLR
connections and for low impedances (600 Ohms). The PLI05 on the other hand with its jack connectors
is better for higher impedances. It covers a wide range from 600 Ohms to over 10 kOhms. The attached
diagrams for harmonic distortion, frequency- and phase characteristics demonstrate this quite clearly. To
prevent loss of level make sure that your input impedance is not higher than the output impedance. Both
devices are suitable for high levels of up to +20dBu.
CONNECTIONG BALANCED DEVICES
Use shielded two-core cables with stereo jack plugs. These are also called TRS jacks, TRS stands for
the Tip, Ring and Sleeve of the plug. A balanced connection only makes sense if your device has a
balanced output. If the device has XLR outputs you will need an XLR to stereo jack adapter cable with
the following assignments: XLR pin 1 to the jacks’ sleeve, XLR pin 2 to the jacks’ Tip and XLR pin 3
to the jacks’ ring.
CONVERTING BALANCED TO UNBALANCED
As mentioned earlier, you can use the PLI01 to make an unbalanced signal balanced. Simply use a
mono jack on the unbalanced side, and a stereo Jack with the same assignments as stated above on
the balanced side of the PLI01. Important: Balanced wiring is a lot less sensitive to interferences com-
pared to unbalanced setups. Unbalanced cables should therefore always be kept as short as possible.
CAUTION:
All Audio transformers are quite sensitive to magnetic fields caused by mains transformers for example.
Before you permanently install the PDI01 somewhere, make sure the location is suitable by temporarily
installing the device.
