Lightweight 19" stereo guitar power amp

Gone are the days of lugging around heavy guitar power amplifiers - and we can be thankful for it. Modern Class D power amps pack an enormous amount of power into a lightweight package - and the Harley Benton GPA-400 stereo guitar power amp is no exception. With dual outputs each delivering 200 watts of power at four ohms, this powerhouse comes in a 19"/1 HU rack format and is the ideal solution for guitarists and bassists who are looking to make their rig powerful enough to always be heard, but want to save their energy for the stage rather than wasting it transporting their gear. Each channel features independent controls for resonance and presence as well as dedicated indicator LEDs for signal and peak, so a full parameter overview is ensured at all times. What is more, the GPA-400's robust 19" chassis weighs in at a mere 3 kg, so it can be easily transported without putting your back out.

Plenty of power for your rack

With an output of 400 watts in mono bridge mode and 200 watts in stereo mode and covering a frequency range of 20 Hz to 20 kHz, the GPA-400 is a real workhorse, and it provides the perfect solution for powering either a single cab on its own or two cabs in a stereo setup. Each channel has a dedicated two-band EQ with a resonance control for bass and a presence control for treble, which lets you make final tweaks to the signal coming from your preamp, pedal board, or multi-effects unit and get the sound you want from the speakers connected. Both channels also have their own indicator LEDs for peak and signal to allow you to visually monitor the incoming signal, and the front panel feature a mute switch to allow complete silence when you are not playing. The GPA-400 also operates without mechanical noise, as there is no internal fan to start getting on your nerves.

THE power amp for stereo rig users on a tight budget

Players who use guitar rigs like the Kemper modelling amp series or Axe FX Fractal systems will find the GPA-400 to be a very interesting alternative to significantly more costly units. This robustly built power amp - manufactured in the time-tested 19" rack format - delivers up to 400 watts at four ohms in mono and 200 watts in stereo, and should thus fulfil a wide range of applications. A glance at the GPA-400's budget-friendly price tag (typical of Harley Benton) of course makes it twice as attractive. All of this means that the GPA-400 is particularly interesting for musicians who are on a limited budget but don't want to miss out on the luxury of amplifying their system in stereo.

High performance for rehearsal room and stage

Whether you are using the GPA-400 with a 1x12" cabinet for practising and jamming at home or pairing it with a pair of 4x12" cabs on stage, this little powerhouse is easily up to both of those jobs. In addition to amplifying your guitar preamp, the GPA-400 also gives you additional scope to shape your sound to suit the room and the speakers connected thanks to its two-band EQ. The fact that the GPA-400 weighs in at just 3 kg and operates without a fan in order to facilitate quiet practice at home is also an advantage that is not to be sneezed at. It has never been easier to have so much power at your disposal wherever and whenever you need it while going easy on your wallet - and your back - at the same time.
