Product Description


Like most of Fearn's products, the VT-24 came about because it was something that D. W. F. needed for his own recording projects. He wanted to record every microphone with VT-1/VT-2 mic preamps, but was running out of rack space in his small control room. A four-channel version of the VT-2 would double my preamp capacity in the same space.

Fearn did not want to compromise on the sound nor on the features of the VT-2. The VT-24 uses the identical circuit and custom Jensen input and output transformers as all our mic preamps. It has four true VU meters, but they are smaller than on a VT-1/VT-2. Specs are the same as a VT-2, and, most importantly, the sound is exactly the same.

The VT-24 has eight tubes, but it runs cool enough that no fan is required, so you can have next to live mics without a problem.

One thing that was eliminated in the VT-24 is the meter switch. But the 48V phantom power, 20dB pad, and special input selection for Low-Z microphones are just like on a VT-1/VT-2. The power switch is on the front panel.
