Delivering up to 500 watts of solid-state power with intuitive tone shaping and practical connectivity, it is built to handle rehearsals, studio sessions and live gigs with ease.
With its musical 4-band EQ, simple front panel layout and rugged construction, the PA 500 keeps you focused on playing rather than menu diving. Plug in, dial in your sound in seconds and enjoy tight lows, articulate mids and smooth highs that let your bass sit perfectly in the mix.
Powerful, Portable Bass Amplification
At just 3.13 kg and with a compact footprint, the PA 500 is easy to transport yet delivers serious output. Offering 500 watts at 4 Ohms or 300 watts at 8 Ohms, it has enough headroom for loud stages while remaining controlled and responsive at lower volumes. The solid-state Class D design keeps things efficient and cool-running, ideal for players who need reliable power night after night.
Musical 4-band EQ for Precise Tone Shaping
The PA 500 features a flexible 4-band EQ with Bass, Lo Mid, Hi Mid and Treble controls, each offering up to +/- 15 dB of cut or boost. This lets you fine-tune your sound to suit different basses, rooms and musical styles, from deep, rounded lows to punchy, forward mids and crisp top end. The straightforward layout means you can make quick adjustments on the fly without losing focus on your performance.
Stage-ready Front Panel Controls
Everything you need is right on the front panel: a standard 6.35 mm mono input jack, Volume control, dedicated EQ knobs and a convenient MUTE switch for silent tuning or quick changeovers. The Power On / Off switch and LED clip indicator keep you in control of your level, helping you avoid unwanted distortion and protecting your speakers from overload.
Practical Connectivity for Live and Studio Use
The rear panel offers a Line-In and Line-Out (both 6.35 mm mono jacks) for integrating with external preamps, effects or recording setups, plus a Speaker Twist output for secure connection to your speaker cabinet. With an IEC mains socket and selectable 120/240 VAC input voltage, the PA 500 is ready to slot into a wide range of rigs and power environments within the specified voltage range.
