FP-MX4
4 Channel Audio Mixer - Microphone or line input and output
The FP-MX4 is a single-channel audio mixing module featuring four identical inputs. Each input accepts either a mic or line level source. The output section provides four mixing potentiometers corresponding to the four inputs. The output section provides both a balanced line (+4 dBu) and balanced microphone level (-45 dBu) output. Both outputs may be used at the same time. The four mixing potentiometers are intended to be set at installation or to be adjusted occasionally. Levels may be adjusted at the mixer using the RDL dual-LED VU meter which displays the mixer output level.

RDL STD-10K
SKU: RDL0561
Each STD module is a resistive branching network with RF filtering on each of the four channels. Any channel, A through D, may be either an input or an output. This permits combining stereo signals into mono inputs, splitting mono signals to multiple inputs, and even combining microphones with output shorting switches into a single amplifier input. The STD modules are available in 150 Ω, 600 Ω and 10 kΩ models. All inputs and outputs are balanced. View details
RDL ST-MX2
2 Channel Audio Mixer - Microphone or line input and output
SKU: RDL0586
The ST-MX2 is used in any application requiring mixing of two audio sources. A mic may be mixed with a line-level music source. Two mics may be mixed to feed the mic or line level input of a power amplifier. A mic or professional +4 dBu line-level mono sum is possible. It may be used to convert mono line-level signals from consumer to professional, or from professional to consumer format. It may also be used as a microphone preamplifier, or conversely to adapt unbalanced or balanced line-level signals into the microphone input of other equipment. View details
RDL ST-UMX3
3x1 Universal Audio Mixer - 3 microphone or line inputs x 1 microphone or line output
SKU: RDL0610
The ST-UMX3 is a three-channel audio mixer for combining mic-level or line-level signals to a single output. A MIC/LINE switch is provided for each input. A separate MIC/ LINE switch selects the output level. Each input features a separate preamplifier circuit, which isolates it from the other inputs. An audio taper single turn gain adjustment is provided for each of the three input preamps. Signals from the three preamps are actively summed and fed to the output amplifier which includes an RDL® dual-LED VU meter.…
