The ST-LCR1 provides double-pole, double-throw dry switching contacts and LED indicator for relay closure. The ST-LCR1 provides momentary operation and is ideally suited where additional switching...

The output is ground-referenced, and drives more than 1 watt RMS into an 8 Ω, load. The output circuit can be connected to any load impedance of 4 Ω, or greater.

The ST-HP3 features RDL',s SupplyFlex power input configuration for operation directly from ground-referenced, floating or bipolar 24 Vdc power.

The MIC INPUT may be wired for balanced or unbalanced operation. A phantom voltage terminal is provided for use with condenser microphones. The phantom input accepts dc voltages up to 48 Vdc and is...

The input and output may be wired balanced or unbalanced. Two LED indicators are provided for adjustment.

The ST-GCA3 constantly adjusts for changes in input levels, bringing up low levels, and reducing gain for high levels. The audio level is constantly adjusted to maintain the correct output. The AGC...

The ST-FS6 module is a passive device with six identical channels. All inputs are fed through a series of ferrite RF suppressors to their respective outputs. All channels are isolated from each other...

The ST-EQ3 features a balanced bridging input, which may be connected unbalanced if desired. The output driver is 150 Ω, balanced, and is intended to drive unbalanced or balanced lines of 150...

The ST-DA3 features RDL',s SupplyFlex power input configuration. The module will operate directly from floating 24 Vdc or bipolar dc power. If a jumper is connected between the PWR minus...

The ST-CX2S features RDL',s SupplyFlex power input configuration for operation directly from ground-referenced, floating or bipolar 24 Vdc power.

For systems also incorporating subwoofers, the LOOP THRU output connects to an input of the RDL ST-CX2S Subwoofer Crossover. The ST-CX2 features RDL's SupplyFlex power input configuration for...

The ST-CL2 is a high performance compressor/limiter designed to maintain a constant average output level and effective peak control over a wide range of input levels. The input and output are line...
