Page 7: Introduction And Key Features
Introduction and Key Features Introduction The Bag End Kairos DSP series of loudspeaker processors represent the current state-of-the-art. Taking ad- vantages of the latest advances in analog to digital conversion and digital signal processing technologies the units achieve performance levels that have only recently been made possible. -
Page 8: The User Guide
The User Guide This user manual gives a progressively more detailed description of the functions of the DSP series. A single page quick reference guide is provided for those users who are experienced with this type of equipment and just need to know how to ‘drive’ the front panel. A detailed explanation of the front and rear panel controls and indicators is contained in the next section. -

Front Panel Channel Select buttons 2x 24 character Limiter Indicators Store and Recall buttons KS26 Input Signal Indicators Parameter Edit Encoders Edit Parameter Output Mute Select buttons buttons Input Signal Indicators A set of three pairs of LEDs indicate signal present, +4dBu and input clip for each channel. The signal present LEDs operate at approximately –40 dBu, giving a useful indication of even relatively low input signal levels. -
Page 10: Text Display
Text Display Preset, channel, parameter and status information is shown on the 2x 24-character text display. In most screens the currently selected channel is displayed on the upper line and the edit parameter on the lower line. To simplify the display and enhance security, some parameters or parameter pages are omitted when not relevant. -
Page 11: Rear Panel
Connectors Power Inlet The Bag End Kairos DSP series unit should be connected to a suitable mains electricity supply using the cable supplied. The processor has a switch mode power supply that is capable of operating with a nominal mains voltage of 85V to 240V, 50/60Hz without re-configuration. -
Page 12: Operation
Selecting a Factory Preset • The Bag End Kairos DSP series processors have a library of Factory Presets designed to suit a range of applications. • Factory Presets contain some parameters that are fixed and hidden from view; the remainder of the DSP parameters are available for user manipulation. -
Page 13: Navigation And Viewing Parameters
Navigation and Viewing Parameters Many of the processing elements in each input and output path have features that may be controlled by the user, such as gain, frequency or limiter threshold. We call these adjustable features parameters. In A Freq Width Gain 100Hz... -

CHANNEL Out1 Freq Width Gain 100Hz 1.4Q 0.0dB EDIT Pressing the edit navigation buttons gives access to the various pages of parameters available for each channel. The currently selected page is shown in the bottom left hand corner of the display, this is omitted on some pages where the function is obvious. -

Page 18: High Pass Filter
High Pass Filter In A Freq Shape 20.0Hz LR24 • Knob a: Frequency, out (off), 20.0Hz to 25.6kHz in variable steps • Knob b: high pass filter type System high pass filtering is provided for the input signal. This is the preferred location for high pass filtering as it affects all outputs and can therefore improve inter-band phase relationships. -
Page 19: High And Low Shelving Filters
High and Low shelving filters In A Freq Slope Gain 100Hz 12dB 0.0dB • Knob a: Frequency, 10.0Hz to 25.6kHz in variable steps • Knob b: Slope, 6 to 12dB / octave in 1dB steps • Knob c: Gain, +/-15dB in 0.2dB steps The frequency is specified as point where the filter deviates by 3dB from the gain value. -
Page 20: Output Channels
Output Channels Gain and Polarity Out1 Gain 0.0dB • Knob a: Gain, adjustable in 0.2dB steps from –80 dB to +20dB • Knob b: Polarity, selectable, normal or reversed with reference to other outputs Delay Out1 Delay 1.50ms • Knob a: Adjustable in variable steps from 0 to 80ms As for input delay, velocity sensitive Parameter Knobs provide finer adjustment at low levels and rapid selection of higher values. -

Page 23: Limiters
These both assume the use of the recommended amplifi- er(s) for a particular Bag End loudspeaker system. In all cases the amplifier should be set for a voltage gain of 26 dB. -
Page 24: Routing
Out1 Thresh 4.0dB • Knob a: Threshold, -40dBu to 20dBu in 0.2dB steps A high performance, low distortion limiter is provided on each output. Threshold is user adjustable; all oth- er parameters are carefully calculated dependant on configuration to provide clean and effective control of signal dynamics. -
