800S is the next step in a series of lightweight high-end amplifiers, following the principle of 400S. With a total weight not exceeding 3,3kg and the application of the newest technics - it becomes a compact tool for both electric and acoustic bassplayers.

Class-D technology makes it an amplifier with a continuous power of 800 Watts. Separate gain controls for both inputs. The LED above input 1 is a clip indicator, turning from green into red as soon as the signal is too high. 

High efficiency rate of 92% and the use of a massive aluminium cooling profile results in a lack of a cooling fan. That makes it a very useful feature, especially while working in the studio environment. Specifications of class-D power amps are highly dependent on the quality of the power supply. That makes the 800S a high-end bass amplifier without any hiss or noise.  is known for its absolute noiseless action due to the use of low-noise components. The input impedance of both inputs is very high (5 MΩ), so piezo pick-ups can be amplified without an external pre-amp.

The first input has a -6 dB switch to reduce sensibility if necessary. This could be the case while using an active bass guitar or a double bass with a separate preamp. The use of a separate preamp for acoustic piezo pickups is not necessary though. Input 1 is also provided with a phase turn switch, allowing to connect an acoustic bass with two different pickups. Setting one pickup out of phase results in a differend sound.

800S is also equipped with a mute out. The internal signal is interrupted and will be available at the mute out to be sent to a tuning gear. The equalizer is a 4-band with frequency ranges at 80, 250, 800 and 2500 Hz (+/- 12 dB). In normal acoustic circumstances the use of the tone unit won't be necessary.

At the back it's equipped with 2 Speakon loudspeaker outputs, a headphone output and a symmetrical line out with a pre/post switch. The pre/post switch controls the source of the line out signal.

The loudspeaker output has a minimal load of 4 Ohms , making it possible to connect two cabinets at 8 Ohms each. Controllable headphone output. Built-in start delay and protected against short circuit and clipping.
