Operation

With both input volume controls turned fully down, switch on the power

(12) to the CLARA speaker cabinet.

The LCD display (1) will light up and show the VOLUME level. Use the

rotary selector (8) to adjust the master output volume between 0dB and

60dB. Keep this setting at 60dB for testing and reduce, if necessary, later.

If a smart phone is paired with the CLARA cabinet, make sure that the Bluetooth receiver is switched on (3)

and play a track from the smart phone to test the speaker, turning up the level control (9) gradually.

If a mixer is connected to the CLARA speaker unit, ensure a signal is present, turn up the mixer output part

way and gradually increase the volume of the input that the mixer is connected to for checking the output

from the speaker. If the sound is present and OK, turn down the mixer and turn up the level on the speaker

to the maximum required output and then control the volume from the mixer.

If a microphone is connected directly to MIC/LINE B input (6), speak into the microphone whilst gradually

increasing the volume of the MIC/LINE B input (11) until the required sound level is reached.

For playback devices connected to the LINE A or B input, play an audio track with the playback device volume

turned up part way and gradually increase the volume of the relevant input so that the output can be checked

and increase to the required output level.

Each CLARA active speaker has an inbuilt Digital Signal Processor (DSP) unit to control the tonal and dynamics

character of the speaker for optimal performance in any given application. This DSP can be programmed

directly from the rear panel or from a windows PC connected to the speaker by a USB lead.

As described above, on power-up, the backlit display will show the master

output VOLUME, and this can be adjusted using the rotary selector. It is

advised to reduce the input levels whilst making adjustments and turn

fully down if powering down the CLARA speaker unit to avoid loud noises.

To access the internal DSP functions directly, press the rotary selector and

the page opposite will be displayed. Turn the rotary selector to navigate

through the listed options and press the rotary selector to select the

highlighted option or setting.

Navigating to the "EQ ..." section and pressing the selector gives access to

a programmable parametric EQ. There are 5 separate EQ bands, named

EQ1, EQ2, EQ3, EQ4 and EQ5.

Each of the 5 bands has fully editable frequency, resonance and gain values.

Turning to "MODE" and pressing the selector offers 5 x DSP profile

settings: NORMAL, JAZZ, POP, CLASSIC and CUSTOM. Rotate the selector

to the required profile and press to select.

The CUSTOM profile is set aside for

user programming. NORMAL is a pre-

set generic setting and JAZZ, POP and

CLASSIC are pre-set as an optimal

profile for different music types.
