The Square ONE range consists of the Square ONE graphic equaliser and the Square ONE dynamics, an 8-channel, 3U configurable dynamics processor. Klark Teknik has historically concentrated on the feature-rich top end of the market but the Square One units address a new price point, making them attractive for medium size rental companies and smaller installations.

Square One Dynamic

The Square ONE dynamics has been designed to provide eight channels of flexible, configurable, high-performance dynamics processing in one 3U package. Users can select the required mode of operation, allowing the multi-mode dynamics processor to function as a default compressor (RMS sensing type); 'vintage' compressor (peak sensing type); broadband frequency-conscious compressor; Hi-Q frequency-conscious compressor (de-esser); limiter; expander or gate. Square ONE dynamics also provides i-TS (intelligent threshold shift) in conjunction with the gate hold function to reduce chattering within the gate; stereo and multi-channel operation, solo buss operation; 6-segment, 3-colour input meter and 10-segment attenuation depth meter.

Square One Graphic

Features of the Square ONE graphic include 45mm faders with integral dust guards (Long-throw faders for maximum accuracy and resolution); signal present and clip LEDs (Maximum input capability of +22dBu); fully balanced inputs and outputs XLR & TRS connectors, both feature extremely high CMRR; relay activated bypass Continues to pass audio in the event of power failure; PROportional Q filters The "Q" or bandwidth of the Square ONE's filters is proportional to the gain applied, and so gives increasing focus on real problem frequencies. This also means that adjacent filters sum together with minimum phase error, providing smooth, ripple-free summation.
This filter mapping is also implemented on the World-leading Klark Teknik DN370, and is the most appropriate for live sound reinforcement; high pass and low pass filters The HPF on graphic equalisers are used to remove unwanted subsonic frequencies (traditionally about 30Hz). The HPF on the Square ONE graphic is set at 80Hz. If using your Square ONE graphic with a large speaker system, then you will almost certainly be using an active crossover, which should provide appropriate subsonic protection. In this case, leave the HPF out of circuit. The Square ONE graphic's LPF is fixed at 12kHz. This is optimal for stage monitoring applications, both loudspeaker and IEM systems, and will increase available headroom as well as providing HF drivers with some thermal protection against ultrasonic frequencies.

When engaged simultaneously, the Square ONE graphic's HPF & LPF give optimal control of the operating bandwidth of most foldback (floor wedge & IEM) transducer systems; universal power supply and roadworthy 3U steel chassis.
