Introduction Introduction Thank you for purchasing a Klark Teknik Square ONE Splitter. Your Square ONE Splitter forms an integral part of the Square ONE range, which was conceived by Klark Teknik to offer audio professionals a suite of easily accessible, high-performance audio equipment, designed to provide no-compromise sonic quality with a feature set that offers all essential facilities and functions.
Introduction All audio connections are on balanced XLRs (wired pin 2 hot) featuring gold plated connectors. The mic inputs and transformer balanced outputs are mounted on the front panel for easy access, and the two electronically balanced outputs are on the rear panel along with the duplicate set of inputs. An integral switch mode power supply automatically adapts to mains voltages in the range 100 to 240 volts (50 to 60Hz).
Introduction Features The Square ONE Splitter has eight channels, each with: • Two mic preamps, based on those used in the acclaimed Midas XL8 Live Performance System1; one drives the two electronically balanced outputs and the other drives the transformer isolated output. • Two paralleled inputs, one front and one rear. • Two electronically balanced outputs (rear panel), derived from the front control knob-adjusted mic preamp.
Introduction How to use the Square ONE Splitter This section shows you how to get the most out of your 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.
Introduction Using the parallel inputs Typically, the mic signals - from different stage locations - are fed to the splitting systems using multi-channel stage boxes and cables. This infrastructure is normally subjected to tremendous stresses during the show and during set up/breakdown, and it is not unusual to develop intermittent faults on some individual signal lines. If this occurs there is normally little time available to de-bug the problem fully before the show.
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. Inspect the Square ONE Splitter unit carefully for any signs of damage that may have occurred during transit and notify the courier immediately if any is discovered.
Getting started 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.
Getting started Connecting to unbalanced equipment Important: We recommend that you only connect balanced devices to your Square ONE Splitter. However, if you do have to connect unbalanced devices, we recommend that you use the Klark Teknik DN100 DI box to balance the signal first. Ideally, you will be making the best use of the low-noise high-headroom balanced inputs of the Square ONE Splitter by connecting to similarly balanced equipment.
Front panel Front panel The front panel of the Square ONE Splitter is divided into three main sections, as follows: 1 2 3 4 1 FIXED GAIN ISOLATED OUTPUT C / PARALLEL INPUT: Eight-channel section containing the paralleled inputs and transformer isolated balanced outputs; see “FIXED GAIN ISOLATED OUTPUT C / PARALLEL INPUT section” on page 9. 2 ACTIVE SPLITTER: Eight-channel section containing the channel controls; see “ACTIVE SPLITTER section” on page 10.
Front panel ACTIVE SPLITTER section All of the switches in this section are of the two-position latching pushbutton type. Each switch, unless otherwise stated, has an adjacent LED for on/off indication, where illuminated LED = switch is on, and extinguished LED = switch is off. 1 OUTPUT level meter (dBu): Dedicated peak reading, four-segment audio level LED meter that follows the output level at all times, no matter how the controls are set.
Front panel Phones, power and media split section 1 LEVEL control knob (dB): Adjustment of the headphones signal in the range 4 (off) to +10dB. 2 Headphone jack: Standard TRS-type 1/4” jack for connecting headphones, enabling you to monitor the solo function. 3 1 Blue POWER LED: Mains power on/off indicator. When LED is illuminated, mains power is on. (There is no mains on/off switch on the Square ONE Splitter.) 4 Yellow MEDIA SPLIT LED: Illuminates to indicate that media split is in operation.
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. The correct mains lead for the country to which the unit was shipped is supplied with the unit.
Rear panel Media split and ground lift switches The output lift and media split switches are deliberately recessed to prevent them being inadvertently switched on or off. Each switch has an LED above for on/off indication, where illuminated LED = switch is on, and extinguished LED = switch is off. 1 Red LED for OUTPUT A LIFT switch. 2 OUTPUT A LIFT switch: Recessed switch for globally disconnecting the internal ground from the OUT A output connector on all eight channels.
Operation Operation Basic operation Caution: Never apply phantom power to any unbalanced input source. Before powering the unit, always check the +48V status of any phantom powered equipment connected to any of the 16 output XLRs on the rear panel. If +48V is detected on any of these outputs the unit will apply +48V to any devices connected to their corresponding inputs (front or rear panel) as soon as the unit is powered up.
Operation Media split mode To switch the unit to media split mode, press the recessed MEDIA SPLIT switch on the rear panel; its yellow LED and also the one on the front panel will illuminate to show that the switch is on. In media split mode, the input to channel 8 - on both the front and rear panels - is distributed to all 16 electronically balanced outputs (rear panel) via its mic preamp, which is controlled via the channel 8 GAIN control knob; all of the meters will follow the output of channel 8.
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.
Applications Example 2 - FOH and MON split, and recorder In this simple live situation the stage mic/line feeds are split to serve the FOH live sound console, a monitor console and an on-site recorder. It is recommended that the transformer balanced outputs are used to feed the recorder or recording console, especially if the grounding scheme is outside the control of the public address (PA) operator.
Applications Example 3 - Pre-mixed broadcast output In this live broadcast application the Square ONE Splitter provides isolated feeds from the group outputs of the FOH live sound console.

More about splitters More about splitters This section is intended to provide some useful background information on mic splitters. Introduction In its very basic form, a splitter accepts mic/line signals and splits each signal for distribution to a number of different processing devices. However, more advanced solutions are required to cope with factors within a sound system that cause signal degradation and produce external noise and radio frequency (RF) interference.
More about splitters Passive parallel splitter The passive parallel splitter has, basically, all of the ‘split’ points wired in parallel, offering no ground isolation or any gain stage whatsoever. Passive parallel splitters are popular at the lower end of the market as they provide a very cost-effective solution as compared with a transformer isolated splitter or an active splitter.

More about splitters Isolated splitter An isolated splitter typically uses a 1:1:1:1 ratio transformer to achieve the audio isolation. The mic input signal is connected to the primary winding of the transformer, with all of the split points derived from the secondary windings. Additional ‘ground lift’ switches may be added to each of the split points providing the option to fully isolate individual parts of the system, if required.
