QUICKSTART
BASS Subwoofers

Dear customer,
thank you for choosing our HEDD BASS professional subwoofer.
You have selected an innovative, clean sounding active subwoofer that we think will open the window to your music at the
widest possible angle.
Please unpack your new subwoofer cautiously. If you discover any damage to the packaging or the speaker itself, don't operate the
speaker and contact your HEDD dealer for solving the problem.
The BASS subwoofers oer precise controls, so we invite you to read through the following section and the manual carefully.
We suggest that you allow the subwoofer to acclimate to the temperature of your room for about an hour before using it.
THANK YOU
Make sure the main power switch is in the "0" position, then connect the power cord to the power socket.
Set the power switch to "1". Please note that the LED becomes green immediately but it may take up to 15 sec
to power up and play audio. Warning: High volume may damage your hearing! Consider lowering the volume rst.
Connect your audio source via the balanced XLR socket and choose the input selection via the „ANALOG/AES“
rotary switch accordingly. Please connect both left and right channels for analog input. Use the Left and Right
outputs to connect your satellites.
As there are quite a number of control knobs on the backplate we recommend to start playing music with all the
markers in the "Up" position: ALL "0" and "↑" POSITION = FACTORY SETTING
