The Yamaha PX3 is a solid choice for DJs needing a reliable and fairly powerful amplifier. It delivers 2 x 500 watts at 4 ohms, which is sufficient for most small to medium DJ setups, providing clear and strong sound without distortion. The amplifier is notably lightweight—about 50% lighter than previous Yamaha models—making it easier to transport to gigs. It includes useful onboard features like digital signal processing (DSP) and Yamaha's D-Contour for better sound shaping, which helps maintain audio quality even at higher volumes.
The unit also offers convenient tools such as a configuration wizard and panel lock to prevent accidental changes, along with event logging, which can be helpful for troubleshooting. In terms of build, it uses metal and plastic to balance durability and weight. The product dimensions are somewhat bulky for its power class, so users should consider the size when planning their setup. The amplifier has a respectable signal-to-noise ratio and keeps distortion low, ensuring clean sound output.
This amplifier suits DJs who want a dependable, easy-to-handle power amp with good sound-shaping features, especially if portability is important. Those needing very high power or advanced connectivity might want to explore other models.
The Crown Two-channel-300W at 4Ω Power Amplifier (XLi800) is a solid choice for DJs looking for reliable and powerful amplification. With a power output of 300 watts, it can handle demanding audio setups efficiently. The amplifier offers stereo, parallel, and bridge-mono modes, making it versatile for different performance needs. It has user-selectable input sensitivity options (0.775V and 1.4V), which adds flexibility depending on your audio source requirements.
For connectivity, it includes electronically balanced RCA and XLR inputs, as well as binding post and speakon outputs, ensuring compatibility with various audio equipment. The forced-air cooling system is efficient in preventing overheating during extended use. Controls are straightforward with two level controls, a power switch, and LEDs indicating signal presence, clip, and fault for each channel, helping you monitor performance easily.
The unit is also relatively heavy at 25.1 pounds, which might be a consideration if you frequently move your equipment. Despite this, the amplifier's positive features suggest it is a reliable and well-regarded option for DJs.
The Rockville RPA16 is a powerful 2-channel amplifier well-suited for DJs and live sound use, offering up to 1500 watts RMS per channel at 4 ohms and 3000 watts bridged into one channel for subwoofers. This makes it capable of driving large speaker setups with plenty of headroom. It supports 4 and 8 ohm speakers, providing flexibility depending on your speaker system. The amp maintains low distortion (less than 0.04% THD) and a high signal-to-noise ratio (over 100dB), which means your sound stays clear and free from unwanted noise during performances. Its built-in limiter and clipping indicators help protect your speakers from damage, a valuable feature for DJs who push volume levels.
The cooling system uses quiet, high-velocity fans, which effectively manage heat without adding distracting noise. Inputs are balanced with a high impedance for compatibility with professional audio gear, and the amplifier offers versatile modes (stereo, bridged, parallel) and crossover settings that help tailor output for different speaker arrangements. It also includes helpful front-panel displays showing volume and temperature, plus a rugged rack-mount design for easy integration into pro setups.
At around 41 pounds, it is a bit heavy and may not be ideal for quick, frequent transport. The size and power make it best suited for stationary or semi-permanent DJ rigs rather than portable use. The RPA16 provides strong power, solid sound quality, and useful protective features, making it a reliable choice for DJs needing a robust amplifier for club or event sound systems.
