The ST-RG1 is a digitally generated 0 to 10 volt Ramp Generator which provides the ideal interface for audio volume control from multiple points with the ST-VCA2. Any number of Up and Down buttons may be connected to the ST-RG1. Sufficient drive is provided from the ST-RG1 to control up to six ST-VCA2s.
VCAs may be controlled from several locations with the optional RLC2 Remote Level Control panel or RUC-4 Universal Remote.
LED level indicator driver circuitry is included in the ST-RG1 for visual indication of relative level.
