Using the Aguilar Tone Hammer 500 is a breeze. First, connect your bass to the 1/4″ input jack. You can then use the EQ section to adjust the bass, mid - level, mid - frequency, and treble to your liking. The “Drive” control, adjustable with the AGS circuit, allows you to add some extra character to your sound. The dedicated tuner output makes it easy to tune your bass without disturbing others.
If you want to use effects, connect your effects unit to the effect loop. The loop adds 6 dB of gain, which helps make most effects work well. For the speaker, use the Neutrik Speakon outputs to connect to your speaker cabinet.
When it comes to the balanced output, the XLR connection has a pre/post EQ and ground lift switch. You can use this to send a clean signal to a mixer or recording device.
Here are some things to keep in mind. Don't expose the amplifier to extreme temperatures or humidity. If you're using the - 10dB pad button, adjust it carefully to avoid over - or under - amplifying your signal.
For maintenance, keep the amplifier clean. You can use a soft, dry cloth to wipe it down. The two whisper fans keep the amplifier cool, but make sure there's enough space around the unit for proper air circulation. If you're not using the amplifier for a long time, store it in a dry place.
