-
If your equipment is no longer functioning properly, if fluids or objects have gotten inside the equipment 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.
-
Clean the equipment using a dry cloth.
-
Comply with all applicable disposal laws in your country. During disposal of packaging, please separate plastic and paper/cardboard.
-

For Equipment That Connects To The Power Mains: -
CAUTION: If the power cord of the device is equipped with an earthing contact, then it must be connected to an outlet with a protective ground. Never deactivate the protective ground of a power cord
-
If the equipment has been exposed to strong fluctuations in temperature (for example, after transport), 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.
-
Before connecting the equipment to the power outlet, first verify that the mains voltage and frequency match the values specified on the equipment. If the equipment has a voltage selection switch, connect the equipment to the power outlet only if the equipment values and the mains power values match. If the included power cord or power adapter does not fit in your wall outlet, contact your electrician.
-
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.
-
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.
-
Whenever possible, avoid switching the equipment on and off in quick succession because otherwise this can shorten the useful life of the equipment
-
IMPORTANT INFORMATION: Replace fuses only with fuses of the same type and rating. If a fuse blows repeatedly, please contact an authorised service centre
-
To disconnect the equipment from the power mains completely, unplug the power cord or power adapter from the power outlet.
-
If your device is equipped with a Volex power connector, the mating Volex equipment connector must be unlocked before it can be removed. However, this also means that the equipment can slide and fall down if the power cable is pulled, which can lead to personal injuries and/or other damage. For this reason, always be careful when laying cables
-
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
Never remove the cover, because otherwise there may be a risk of electric shock. 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 accidentprevention 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-pressure 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.
CAUTION! IMPORTANT INFORMATION ABOUT LIGHTING PRODUCTS
- Do not look into the beam from a distance of less than 40 cm.
- Do not stare into the beam for extended periods at short-to-medium distances.
- Do not view the beam directly with optical instruments such as magnifiers.
- Under some circumstances, stroboscopic effects may trigger epileptic seizures in sensitive individuals! For this reason, persons who suffer from epilepsy should always avoid places where strobe lights are used.
CONTROLS
-
Mono-Switch:
Locate the mono switch between the XLR output sockets. When pressed (recessed) the stereo signal is merged to a mono signal via a transformer-matrix. An Identical output signal is then available on both output sockets. This way the PLI04 can also be used as a signal splitter. In this setup only input and output are isolated via transformer. The grounds of the XLR sockets are not isolated between each other. -
Ground-Lift-Switch:
A galvanic (electrical) connection between two mains powered devices is often undesired as it can lead to ground loops. Ground loops induce a low frequency hum or noise due to compensating currents though the ground lead. In addition, computers and similar devices can also cause high frequency noise on the ground lead. The PLI04 therefore implements high quality audio transformers (coupling transformers), which in combination with the ground lift switch can reduce noise induced by ground loops and ground problems in general. Press the according switch to lift the ground – in this case there is no physical/mechanical (electrical) connection between input and output and compensating currents are thus suppressed. -
Soft-Ground-Switch:
With this switch the ground connections are coupled via an RC-circuit. This circuit cuts off high frequency
noise (such as from a computer) on the ground lead and in addition suppresses low frequency humming.
CONNECTION
Connect the line outputs of your input device to the suitable input connectors of the PLI04 using high quality shielded cables. The PLI04 offers several options: 6.3mm Jack sockets suitable for mono or stereo connectors, Cinch/RCA sockets or a stereo 3.5 jack socket.
We do not advise the simultaneous use of different connector types as this can lead to interferences.
Connect the outputs of the PLI04 to the microphone inputs of your mixer using balanced and shielded microphone cables. For stereo signals you will need two channels on the mixer – remember to pan the channels left and right to obtain a true stereo signal.
NOTE: IF YOU ARE ONLY USING ONE INPUT SOCKET, BE SURE TO USE THE RED RCA SOCKET AS THIS IS THE ONE CONNECTED TO THE HOUSING GROUND.
