This user manual introduces the features and usage methods of the Yamaha P4500/3200/1600 series power amplifiers. These amplifiers feature high power, superb quality, high reliability and stability, guaranteeing the highest possible audio performance.
This manual provides instructions for the Yamaha P4500, P3200, and P1600 series power amplifiers. It details the controls and functions found on the front and rear panels, including the POWER switch, indicators, and various input/output terminals. The document explains three operating modes: STEREO, PARALLEL, and BRIDGE, along with specific connection diagrams for each.
| Minimum Impedance (Stereo/Parallel) | 4Ω |
|---|---|
| Minimum Impedance (Bridge) | 8Ω |
| Heat Sink Overheat Threshold | 85°C |
The three modes are STEREO, where channels A and B operate independently; PARALLEL, where a mono source is output by two amp systems; and BRIDGE, where the unit operates as a single high-power amplifier.
The CLIP indicators light up when the respective channel's output signal distortion exceeds 1%, which is usually due to excessive input signal levels.
The minimum load impedance for the speaker system in Bridge mode is 8Ω.
