Manual abstract:
Main features of the P4500/P3200/P1600 series · Three types of input jack (balanced XLR type connectors, balanced phone jacks, and barrier strip), and fiveway binding post output jacks are provided, allowing use in a wide variety of situations including installed applications. · Three operating modes are
provided: STEREO mode in which CHANNEL A and B operate independently, PARALLEL mode in which a mono source is output by two amp systems, and
BRIDGE mode in which the unit operates as a single high-power amplifier. · A SIGNAL indicator and CLIP indicator is provided for each channel. · The
PROTECTION indicator shows the status of protective circuitry such as power-on/off protection, output muting, and the DC detection circuit. The TEMP
indicator warns of heat sink overheating. · Variable-speed low-noise fan(s) ensures high reliability even under demanding conditions. This owner's manual
covers the three models P4500, P3200 and P1600. @@@@@@* This applies only to products distributed by YAMAHA KEMBLE MUSIC (U.K.) LTD.
English This series of audio amps was developed from Yamaha's wealth of experience in building PA equipment and its tradition of careful attention to every
detail of circuit design. @@Avoid excessive heat, humidity, dust and vibration. @@@@2. Ventilation Allow a distance of 10 cm between the unit and the
wall so that heat generated from the unit will be released effectively. Also, allow enough space between the unit and other devices.
If you mount the unit in an audio rack, keep a space of 10 cm on the top panel, and a space of 1 cm to the side panel. Remove the rear panel of the rack or
open a vent hole. If heat release is inadequate, the unit will retain heat inside the unit, which may cause a fire. 3. Avoid physical shocks.
Strong physical shocks to the unit can cause damage. Handle it with care. 4. Do not open the case or attempt repairs or modifications yourself. This product
contains no user-serviceable parts. Refer all maintenance to qualified Yamaha service personnel. Opening the case and/or tampering with the internal
circuitry will void the warranty. 5. Make sure power is off before making or removing connections. Always turn the power OFF prior to connecting or
disconnecting cables.
This is important to prevent damage to the unit itself as well as other connected equipment. 6. Handle cables carefully. @@7. Clean with a soft dry cloth.
Never use solvents such as benzine or thinner to clean the unit. Wipe clean with a soft, dry cloth. 8. Always use the correct power supply. @@@@@@@@3

from the speaker terminals. · Speaker fuse The output capacity of your amplifier is very high: 460 W+460 W (8) in stereo and 1240 W (8) in monaural on the
P4500; 340 W+340 W (8) in stereo and 880 W (8) in monaural on the P3200; 160 W+160 W (8) in stereo and 400 W (8) in monaural on the P1600.
Be sure to use a speaker system that has sufficient input capacity. @@After removing approx. @@@@@@max. @@@@The amplifier load is excessive.
The heat sink temperature has exceed 85°C.
Remedy Locate and correct the cause of the short. Use a speaker system with an impedance of at least 4 (stereo) or 8 (bridge). Check the ventilation slots, and
improve the airflow around the amplifier. Check the amplifier ventilation conditions and take appropriate measures to improve airflow around the amplifier.
Consult your dealer or nearest Yamaha service center. Protection Circuit CLIP indicator lights. The PC limiter circuit operates to protect the power
transistors. TEMP indicator lights. Warning by the TEMP indicator. The heat sink temperature has exceeded 95°C.
PROTECTION indicator lights. The thermal protection circuit operates to protect the power transistors. A DC voltage of +/2 V or greater was generated in
the power amplifier's output circuit. The relay operates to protect the speaker system. 10 .
