TROUBLESHOOTING

No Sound • Is the loudspeaker cable connected?• Is the SPEAKON cable connector correctly inserted? turn it clockwise until it clicks.• Are you sure your power cable works properly? check it using a cable tester or replacing with a newone.

As soon as the music gets loud, the high frequency shuts down• The HF driver protection trips to protect the HF driver from excessive signal: turn down the volume and mid/high tone controls.

Distorted Sound • Input signal level is too high. Turn down your level controls.

Different channel level• Check if are using a balanced cable for one channel and an unbalanced one for the other, as this would cause a considerable difference in channel levels.• Be sure that your loudspeaker system is fully connected and both loudspeakers have the same impedance.

Noise / Hum• Enable GND LIFT button on rear panel, if the problem persist press all GND LIFT buttons for all system's amplifiers.• Whenever possible, preferably use only balanced cables. Unbalanced lines may also be used but may result in noise over long cable runs.• Sometimes it helps to plug all audio equipment into the same AC circuit so they share a common ground.

CE CONFORMITY

• Proel products comply with directive 2004/108/EC (EMC), as stated in EN 55103-1 and EN 55103-2 standards and with directive 2006/95/CE (LVD), as stated in EN 60065 standard.

• Under the EM disturbance, the ratio of signal-noise will be changed above 10dB.

INSTALLATION AND DISCLAIMER

• Proel products have been expressly designed for audio application, with signals in audio range (20Hz to 20kHz). Proel has no liability for damages caused in case of lack of maintenance, modifications, improper use or improper installation non-applying safety instructions.
• The installation of these speakers is provided for indoors, in case of use outdoors be sure that the speakers are installed correctly in a safe location protected from wind, rain and humidity. To avoid performance deterioration of mechanical, acoustics and electrical parts is not advisable to leave these speakers exposed outdoors for a long period of time, so we suggest a temporary installation for the limited sound events.
• The installation of these speakers is provided for floor or by means of specific stands able to support their weight. Therefore avoid installation on unstable elements such as: furniture, chairs and vibrant surfaces as stages or other speakers without appropriate fix point specifically designed to avoid speaker movement. Then avoid the use of inadequate supports, we suggest to use PROEL stands and accessories only.
• In case of the speakers are provided of rigging points: DO NOT SUSPEND THE SPEAKERS FROM THE HANDLES, use exclusively these rigging points. Consult professional rigger or structural engineers prior to suspending loudspeakers from a structure not intended for that use. Always know the working load limit of the structure supporting the loudspeakers. Always make sure that the rigging hardware minimum rating is at least five times the actual load, speakers and rigging hardware.
• Locate the speakers as far away as possible from radio or television receivers or other sensitive equipment. These speakers have a strong magnetic field which can induce hum and noise into unshielded devices that are located nearby with consequent deterioration of reception of image and sound.
• Proel S.p.A. reserves the right to change these specifications at any time without notice.
• Proel S.p.A. declines any liability for damages to objects or persons caused by lacks of maintenance, improper use, installation not performed with safety precautions and at the state of the art.

GENERAL INFORMATION

Thank you for having chosen a PROEL product.

The LITE Series by PROEL is an extended range of active and passive speaker systems with plywood cabinet offering the renowned PROEL sound and a high-level performance in a reliable and affordable package. For the construction of the cabinets we have used plywood, a very lightweight and durable material that makes moving and installing these speakers very quick and easy. Strong, anti-scratch paint and steel grilles with an internal foam layer provide proper protection for years of service. The dual-angle pole holder featured in LT8, LT10 and LT12 models offers the possibility to obtain a more uniform coverage of the audience.

For the high frequency reproduction of LITE Series we have designed wide-dispersion horns, able to provide constant coverage for large audiences and detailed response with low distortion. The high-excursion woofers, together with carefully tuned vented cabinets, offers an extended response with deep and tight basses.

4 passive models are available, featuring carefully designed crossover filters with HF electronic protection. The choice of black or white cabinet, built-in flying points and a wide range of accessories make them suitable for any kind of fixed installation.

The LT loudspeaker systems can be combined with the SW subwoofers capable of providing the perfect low frequency extension for each model of the series.

INSTRUCTIONS (FIG. 1 / 2 / 3)

1. INPUT (SPEAKON)

External amplifier power input: this is the connector where you plug in the power cable coming from your power amplifier or powered mixer. The powered signal is filtered by an internal passive crossover that splits the power signal into a low frequency section, sent to the woofer, and a high frequency section, sent to the tweeter/driver. The frequency transition is around 2KHz. The INPUT has this pin connection:

PIN1+ (or TIP): positive power signal (usually red wire)

PIN1- (or SLEEVE): negative power signal (usually black wire)

2. LINK (SPEAKON)

Output of the power signal to be sent to an another satellite loudspeaker. INPUT and LINK connectors are connected in parallel.

CHOOSE THE AMPLIFIER POWER

We give you three power numbers: continuous, program and peak.

So these data suggest you can use any amplifier with a power capability in the range between continuous and program, but this rule is valid only if the amplifier never clip any time.

Preventing loudspeaker damage caused by clipping, that is likely the number one cause of damage, and assuming you want to use the full capability of the loudspeaker, we recommend the use of an amplifier with a built-in limiter to prevent clipping, in this case the rated power capability must be in the range between continuous and program power rating of the loudspeaker into the same nominal impedance (tipically 4 or 8 ohms):

• To obtain the best result using 4 (as single 8 ohm speaker for each channel) to 8 (as parallel 4 ohm speaker for each channel) LT6P connected in stereo, we suggest the use of PROEL AUP4150 amplifier.
• To obtain the best result using 2 (as single 8 ohm speaker for each channel) to 4 (as parallel 4 ohm speaker for each channel) LT8P connected in stereo, we suggest the use of PROEL HPX-900 amplifier.
• To obtain the best result using 2 (as single 8 ohm speaker for each channel) to 4 (as parallel 4 ohm speaker for each channel) LT10P connected in stereo, we suggest the use of PROEL HPX-1200 or DPX-1000 amplifier.
• To obtain the best result using 2 (as single 8 ohm speaker for each channel) to 4 (as parallel 4 ohm speaker for each channel) LT12P connected in stereo, we suggest the use of PROEL HPX-2400 or DPX-1500 amplifier.

IMPORTANT: Clipping occurs when the signal at the output of any device in the system (not just the amplifier) reaches its maximum level. Proper operation of a sound system includes being aware of the types of audio signals being reproduced, controlling the output levels accordingly, and operating all the devices in the system so that no clipping occurs within the signal chain.
