Q: How can I control my HD147 via MIDI?
A: Please check the Appendix C on your Pilot's Handbook, you will have a list of MIDI program changes and their relation with the HD147 channels. So channel 1A would recall program 1 on your MIDI device. You can either overwrite program 1 on your device with the effects you want to use with channel 1A or you can go to the preset you want to use and internally reassign that preset to MIDI program 1 (if your device offer that option). You can also set the Expression pedal on a MIDI controller to the MIDI CC# you wish to control - for example if you want to control the Delay Mix with it set the CC# to 34. Please see the bottom of this document to download the HD147 manual.

A: The HD-147 is rated at 150w/channel RMS. 147 decibels is the level of loudness at which your head explodes. What we're trying to say is that this puppy is loud.


Q: How many watts are my two 16 ohm cabs going to pull per side with my HD-147?
A: A solid state amp without an impedance switch puts out more power with a lower speaker load. However, we do have an impedance switch in the back of the amp. The purpose of the switch is to make sure the amp puts out the same amount of power as long as it sees the correct load.


So for your set up, you would plug one cab into one of the RIGHT jacks and the other into one the LEFT jack. Set the impedance switch to 16 ohms. Your amp should put out 150 watts per side.
