Pinhl - A 3 Channel Passive Low Pass Gate

Pinhl is a vactrol-based 3 channel passive low-pass gate. Each channel of pinhl features 3 different tones selectable with the switches on the front of the panel. With the switch in the upward position, the channel is in low pass mode with a mild cutoff. When the switch is in the down position, the tone is darker with a stronger level of filtering. In the middle position, the channel bypasses the filtering circuit and acts as a passive vactrol-based VCA 4HP
