Power Options
1. 9-Volt Battery
Squeeze the tabs on top of the preamp together and the battery drawer will pop out. Snap in a fresh 9-Volt
alkaline. To conserve the battery, unplug the input of the Platinum Bass when you are not using the preamp.
2. 48-Volt Phantom Power
Use an XLR cable to connect the Platinum Bass to a mixing board with 48V phantom power. When you turn
on the 48V phantom at the mixer, the green 48V phantom LED lights up, the 9V battery shuts off and the
Platinum Bass draws power through the XLR cable.
The green 48V phantom LED may not light up once you switch on phantom power. This means the phantom
power from the mixer is not delivering enough voltage. For insurance, keep a fresh 9V battery in the preamp.
The battery will take up the slack if the phantom power is too low.
3. AC Adapter Input
Use only a well filtered and regulated AC adapter with a 9-Volt DC output. We
recommend the Fishman 910-R. Use of a non-recommended adapter may void
the warranty and damage the unit.
Input—Plug your bass in here
When you plug into the input jack, the 9-Volt battery switches on. Remember to unplug the input jack when
you are not using the preamp to save the battery. Turn down your amp or mute your mixer input before you
plug into the Platinum Bass input to protect your speakers (and your ears) from loud pops.
