The ALTO GATE from Alto Pro Audio is a four-channel expander/gate that features extensive controls for each channel of the unit. Each channel can be independently switched to function in either mode, while a semi parametric side-chain EQ is provided for each channel to help with correct functioning of the gate or expander.
The ALTO GATE is housed in a 1U 19" rack-mount chassis and provides balanced inputs and outputs. A 7-step LED meter shows gain reduction, while a 3-step LED indicator provides information about the signal levels and functioning of the expander/gate. Both the meter and indicator are available for each channel.
