Square One Splitter (Klark Teknik) £645.94
Description
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.
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. Standard +48V 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.

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.
- One transformer isolated output (front panel), derived from a second fixed gain preamp. Each channel is clearly labelled and includes the following controls:
- Rotary gain switch with nine positions. Range is from 0dB to +40dB in 5dB steps.
- +48V phantom power switch with adjacent LED for on/off indication.
- 30Hz high pass filter switch with adjacent LED for on/off indication.
- Solo switch with adjacent LED for on/off indication.
- Output meter with four LEDs, which indicate -15dB, 0dB, +12dB and +21dB.
- Additional features include:
- Headphone output (1/4 jack) and level control to monitor the solo bus.
- Two global ground lift switches, one for each set of electronically balanced outputs.
- Media split switch for routing channel 8 to all 16 electronically balanced outputs.
- Phantom power sensing for remotely enabling +48V on the inputs when phantom power is activated from any attached console.
- Male (output) and female (input) XLRs with gold plated connectors.
- Power LED for on/off indication.
- Mains supplied via an IEC socket on rear panel.
- Fuse drawer contains easily replaceable mains fuse and a compartment for a spare.
