Noise / Hum
• 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.

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.
• These amplifiers are adapted in a properly ventilated, standard professional 19" rack. These units feature ventilation holes on the front and back
panels. Absolutely do not obstruct the ventilation holes. Blocked ventilation can cause damages and fire.
• Do not locate sensitive high-gain equipment such as mixer, preamplifiers, recorders or AD/DA conversion units directly above or below these
amplifiers. Because these amplifiers have a high power density, it ha a strong magnetic field which can induce hum into unshielded devices that
are located nearby. If an equipment rack is used, we recommend locating the amplifier in the bottom of the rack and the mixer, preamplifier or other
sensitive equipment at the top.
• Locate the speakers as far away as possible from radio or television receivers or other sensitive equipment. These amplifiers 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.

or a compressed air gun.
• These amplifiers have been designed with CLASS I construction and must be connected always to a mains socket outlet with a proctetive earth
connection (the third grounding prong).
• Before connecting the product to the mains outlet make certain that the mains line voltage matches that shown on the rear of the product, a
tolerance of up to ±10% is acceptable.
• To disconnect these equipment from the AC Mains, disconnect the power supply cord plug from the AC receptacle.
• Inside the amplified loudspeakers are present special safety devices such as:
ü
Transformer and amplifier over-heating protection.
ü
Protection against excessive power applied at each speaker.
•
THE REPLACEMENT OF FUSES INSIDE THE APPARATUS MUST BE MADE ONLY BY QUALIFIED PERSONNEL.
•
CHECK THE CONDITION OF THE PROTECTION FUSE, ACCESSIBLE OUTWARD, ONLY WITH THE APPARATUS SWITCHED OFF AND
DISCONNECTED FROM THE MAINS LINE OUTLET.
•
REPLACE THE PROTECTION FUSE ONLY WITH SAME TYPE AS SHOWN ON THE PRODUCT.
