About the Square ONE Splitter
The Square ONE Splitter is a user-friendly, high-performance, eight-channel, active microphone (mic) splitter
designed for live sound reinforcement. Housed in a rugged and compact 2U rack enclosure, the Square ONE
Splitter offers a cost-effective and space-effective method of providing up to 24 outputs from 8 sources. In
addition, the Square ONE Splitter can also function as a 1 x 16 media splitter.
The Square ONE Splitter can distribute up to eight mic or line level signals to multiple locations, while
maintaining signal integrity and minimising noise interference. Its primary application is to split the audio
signals on-stage into individual feeds for front of house (FOH), monitoring (MON), multi-track recording, live
broadcasting or indeed any other requirement; see Figure 1, “Typical channel I/O connection options,” on
page 2. Although the Square ONE Splitter is a cost-effective unit, its signal integrity and audio performance
mean it can be used with any console, and the quality of its preamp and circuitry can enhance the audio
performance of lower cost consoles.
The Square ONE Splitter has eight channels, each consisting of two parallel inputs, two preamps, and a total
of three balanced outputs. Two of the outputs (identical) are electronically balanced, while the other is
transformer isolated. Both paralleled mic inputs feed two integral, superbly specified mic preamps, which are
based on the circuitry used in the DL431 Mic Splitter (part of the acclaimed Midas XL8 Live Performance
System). One preamp provides adjustable gain and drives the two electronically balanced outputs at
increased levels (up to line level), while the second provides a fixed gain copy of the input and drives the
transformer isolated output.
Channel controls consist of: solo, filter and phantom voltage pushbutton switches each with an adjacent LED
for on/off indication; a gain control knob; and a dedicated peak reading meter for displaying the output at all
times. The solo system allows any channel(s) to be monitored via the integral headphone amplifier. The gain
control knob is used for optimising the preamp gain. St48V phantom powering is individually
switchable on each channel and has remote operation by virtue of its unique phantom voltage sensing
feature.
Additional controls include a headphone level control (just above a headphone jack), a global ground lift
switch per set of electronically balanced outputs and a media split switch. The media split switch activates
media split mode, in which the output of channel 8 is distributed to all 16 electronically balanced outputs.
