POWERING MODES GETTING STARTED

1. DC Adapter: EBS recommends the use of the EBS AD-9 DC

power supply, which supplies a well-stabilized power to the
EBS MicroBassII.

2. EBS Phantom Power™: The Phantom Power option allows

you to power the MicroBassII from another EBS product such
the GormET/Drome bass combos or EBS-active cabinets and so
on. When using the phantom power, you need to connect a
stereo ¼” cable between the OUTPUT from the EBS­MicroBassII and the input jack of the amplifier, or if option is
available on the amp, to the effect return jack. Please refer to
the amps user manual on how to engage this on the amp.

3. 48V Phantom: This is the standard microphone phantom

power option found on mixing consoles and is fed through the
balanced XLR output. Refer to the operating instructions of the
mixing console being used for further reference on how to
activate the 48V phantom power.

4. 9V Battery: Use a long-life alkaline battery for best

performance. Note that the battery doesn’t need to be removed
when using another powering mode. The battery will not be
surged or charged.
