The compact, versatile headphone amplifier able to get the most from any professional headphone. Practically speaking, HP 24 not only allows up to 4 users to listen at the same time but also customizes the sound experience to suit the needs of sound engineers, musicians, and performers, while maintaining the optimal audio performance.
HP 24 perfectly combines the ability to apply high gain with very low distortion levels. The amplifier features L/R balanced inputs. The central knob controls the amplification level of the audio signal, while the LED meter displays the stereo audio level, visually reporting possible saturation/clipping.
Each of the 4 channels has an independent level control. A dedicated button allows switching the signal from stereo to mono and vice versa, when necessary. In addition to this, auxiliary input and output also allow multiple HP-24 modules to be connected together, increasing the total number of available channels when needed. The ground terminal eliminates any buzz due to connection between different devices.
The amplifier is supplied with an external power supply unit with interchangeable plugs (EU/UK/US).
