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.
