Bass guitar combo with a power of 40 W. The combo has one instrument input. The "gain" control adjusts the level of the input signal in the preamplifier, so you can achieve a slightly distorted sound. When the compressor is on, it controls the compression rate. Other control elements include the main volume and a 4-band equalizer with split mid-range frequencies, with which you can better adjust your preferred sound. The AUX input is used to play music from an external device, e.g. MP3, smartphone. Thanks to the headphone output, silent exercise is possible. Output D.I. Out allows you to get a balanced low-impedance output signal from the preamp before Master-Volume, but after any tonal correction. It serves for the direct output of the signal from the amplifier to the mixing desk or additional power amplifier.
