A dual-channel microphone amplifier that delivers high performance at an affordable price. It offers optional input impedance, which affects the performance of any dynamic or tape microphone. It is possible to choose between dual mono / stereo performance. The preamplifier can be used at low or high voltage of two integrated 12AX7 lamps, which allows higher variability of tone and power. Its body is made of solid steel with a front panel made of anodized aluminum and can be connected to a rack. The front panel has VU and LED indicators and is controlled by potentiometers gain, impedance, output level and low cut filter for each channel. It is connected using XLR and 6.3 mm connectors. Impedance: 150 - 3000 Ohm. Frequency response: 15 Hz - 120 kHz. Dimensions: 222 x 482 x 88 mm. Weight: 4.5 kg.
