Fuse drawer contains easily replaceable mains fuse and a compartment for a spare. 1. The mic input of the Square ONE Splitter is based around the same circuitry as used in the DL431 Mic Splitter, which is part of the Midas XL8 Live Performance System, and features exceptionally low noise and distortion, combined with generous headroom. -
Page 16: How To Use The Square One Splitter
Using the main inputs To maximise the sonic benefits of active splitting, the Square ONE Splitter should be located close to the mic sources and connected to them as directly as is practical. In this way the unit can provide active drive to all the distributing cable systems. -
Page 17: Using The Parallel Inputs
If this occurs there is normally little time available to de-bug the problem fully before the show. However, the Square ONE Splitter provides a solution for such circumstances by providing an additional parallel input on the front panel of the unit for emergency connection of a spare mic or individual replacement cable. -
Page 18: Getting Started
Getting started Observing the guidelines in the “IMPORTANT SAFETY INSTRUCTIONS” and “PRECAUTIONS” sections towards the front of the manual, carry out the following to get your Square ONE Splitter unit fully operational. Unpacking Carefully unpack your Square ONE Splitter equipment package. -
Page 19: Connecting The Power Cable
Making sure that the mains power at the power outlet is off, connect the mains cable supplied with your Square ONE Splitter to the mains power outlet and then to the mains socket at the rear of your unit. Connecting the audio cables Making sure that all equipment is switched off, connect your Square ONE Splitter to the rest of your audio equipment as shown in the following subsections. -

Rear panel Rear panel The rear panel provides the power and primary I/O connections for the Square ONE Splitter. Additionally, the media split and ground lift switches are adjacent to the channel 8 connectors. You will find important information, such as warnings and cautions, power supply and fuse specifications, safety and compliance standards markings etc., printed on the left-hand side of the panel. -

(front or rear panel) as soon as the unit is powered up. Connect all condenser mics and active DI boxes to the Square ONE Splitter before applying phantom power. Ensure that the sound system level is turned down at this stage to prevent switch-on thumps or acoustic feedback. -
Page 27: Media Split Mode
With a ground lift switch switched on, pin 1 of each of its associated output XLRs will still be connected to chassis ground via capacitors. This provides an a.c. path to ground, while blocking any d.c. current flow resulting from a ground loop condition. Square ONE Splitter... -
Page 28: Applications
Applications Applications The following examples illustrate just a few of the many possible uses of the Square ONE Splitter in a live situation. Example 1 - FOH and MON split, and broadcast out In a live broadcast situation, the Square ONE Splitter may be used to split the stage mic/line signals at source. -

Page 35: Introduction
These factors include the number of splits required and the length of cable runs, and also the inherent problems imposed by the low level of the mic signal and multiple-grounding. The types of splitter and how they are designed to overcome these problems are discussed in further detail in the following subsections. Square ONE Splitter... -
Page 36: Passive Parallel Splitter
This can potentially lead to ground loop problems if parts of the system are powered from different sources. For example, the PA company may have set the whole system up perfectly using one grounding regime, an independent broadcaster then arrives and has to use a portable generator, adding another grounding source. Square ONE Splitter... -
Page 37: Isolated Splitter
Phantom power (+48V) will also need to be provided for the mics, which may entail connecting one of the consoles in a passive parallel splitter-type configuration or adding a separate supply. Square ONE Splitter... -
Page 38: Active Splitter
In addition, a transformer isolated output - normally derived as a copy of the post-preamp signal, but on the Square ONE Splitter is tapped off before the gain stage - is buffered and driven, making it relatively safe from external interference. This would typically be used for broadcasters who prefer to add their own gain and may also be running their system from a different power source. -
Page 39: Balanced Audio
(CMRR). The electronically balanced input and output connections of the Square ONE Splitter have the benefit of high common mode rejection (CMR), which eliminates externally induced interference such as mains hum etc. CMR is the ability of a balanced input to reject the part of the incoming signal that has the same amplitude and opposite phase on both input terminals, referenced to ground. -
