Alice MonoPAK MKII – Stereo to Dual Mono Converter

Product Overview

The Alice MonoPAK MKII is a compact stereo to dual mono level-matching unit that converts a balanced-line stereo input into two fully buffered balanced-line mono outputs. Both mono outputs are electronically buffered and independently adjustable via multi-turn presets accessible from the front panel, providing around 10dB loss to 20dB gain referenced to a 0dB stereo input. This makes the Alice MonoPAK MKII ideal for feeding separate mono destinations from a stereo source while maintaining correct operating level, low noise and high headroom in professional studio and broadcast environments.

Key Features

• • Balanced-line stereo input to dual fully buffered balanced-line mono outputs for flexible routing.

• • Independent gain trims on each mono output using front-access multi-turn presets, offering approximately 10dB loss to 20dB gain relative to 0dB input.

• • Bridging-balanced audio inputs with input impedance above 20k ohms, preserving source loading and signal integrity.

• • Mono balanced outputs on Neutrik XLR connectors, which can be wired unbalanced when required.

• • Wideband 20Hz–20kHz frequency response with typical tolerance around ±0.1–0.2dB for transparent audio.

• • Common-mode rejection greater than 60dB, low noise around -100dB ref +8dBu at unity gain and distortion below 0.005% at typical operating levels.

• • Maximum input and output levels up to about +25dBu, giving ample headroom for professional line-level systems.

• • Mains powered from 230V AC (115V available to order) with low power consumption in a rugged compact metal enclosure suitable for desktop or rack-mount kits.

Applications

Use the Alice MonoPAK MKII to derive separate mono feeds from a stereo programme bus for recorders, telephone hybrids, codec inputs or PA sends, or to feed identical mono signals to two different destinations at optimised levels. Its high common-mode rejection, low noise and wide headroom make it suitable for studio, OB and fixed broadcast installations where reliable stereo-to-mono conversion and level control are required.
