The DVM-120-PBS is an ideal tethered, purely analogue (zero latency) and powerful personal monitor solution. The central unit provides up to 4 beltpacks with the signal plus the required voltage. It offers a stereo IN and also an auxiliary sub-input, which can be activated individually for each beltpack output. This is often used for command functions in the studio or for the conductor.
The beltpack contains the actual headphone amplifier. It features 1 level control, 1 mute switch, 1 balance control as well as the tone control. The beltpack can be switched to either stereo, dual-mono or sub-input operation mode. For dual-mono operation mode only the selector switch on the bodypack is used, while the balance control determines the mix level for the two input signals. For the mix mode plus sub-input both the selector switches on the bodypack and on the central unit are needed. Now the balance control is used to determine the mix level of the combined stereo signal and the sub-input.
The power for the central unit is provided by an integrated wide range power supply . When designing the product, we attached great importance to ultra low noise and high amplifier performance in the bodypack.
The inputs are electronically balanced, the stereo input can be switched from +4 dBu to –10 dBV nominal level. The connection between the
devices is made by using off-the-shelf microphone cables (max. 50 m).
