- Page 3 Each Amulet Ultra Dual Mono Preamp has 2 thumbwheel controls - VT has Master Volume plus a Tone control (high-end roll off), Ultra DV has 2 Volume controls that give you on the fly control of the volume of each pickup separately (see Page 4). We recommend that you make sure the volume thumbwheel is set to a lower (or off) position when plugging into an amplifier, and then adjust to your desired volume to avoid any unpleasant surprises.

- Page 6 INSTALLING YOUR AMULET ULTRA SYSTEM For detailed pickup installation instructions, please see our guide at https://tranceaudio.com/support/ It is very important to prepare the surface of the guitar in any spot where you are going to apply adhesives, whether it is the Velcro patch used for the battery bag and preamp, the stick-on cable clips, or the pickups themselves.
- Page 7 MOUNTING THE PREAMP The Amulet Ultra preamp module is extremely lightweight, and so it’s fairly easy to securely mount it to the bass side of the soundhole on most guitars using the Velcro supplied with the system. Most guitars will have a brace mounted near the soundhole, and this brace varies a lot in size and location.
- Page 8 Once the two Velcro surfaces are mated, wiggling the preamp back and forth and twisting it slightly will create a better connection between the Velcro hooks and loops and a more secure mounting for the preamp. The preamp modules have the hook portion of the Velcro already applied, so the loop portion of the Velcro is applied at the soundhole;...
- Page 9 The Pickup Input Assembly and Endpin/Battery Clip Assembly jacks have a keyed design so that it only plugs in correctly with the plug oriented in ONE DIRECTION. This is called a polarized connector, and it insures that all of the cable wires get hooked up correctly during installation.
- Page 10 The endpin connector socket is easily visible at the left rear of the unit, while the input connector socket for the pickups is recessed somewhat inside the unit, directly lined up with the “INPUT” label on the top cover of the unit.

Page 11: Trim Control
TRIM CONTROL Each preamp channel has its own easily accessible gain trimmer that allows you to set the perfect balance between the pickups. These can also be used to match the level of your instrument to your amplification system, and even match levels between multiple instruments allowing for smooth transitions between instruments during a performance. -
Page 12: Powering The System
POWERING THE SYSTEM - Battery/Phantom Power Switch Your Amulet Ultra preamp can be powered by a single 9V battery when the switch is set to B (towards the thumbwheel controls), or by 48v Phantom power when set to P (towards the rear of the preamp). Once a new battery is attached to the battery cable, make sure it is secured in the battery bag with the Velcro closure securely fastened,... - Page 13 ENDPIN JACK INSTALLATION The endpin jack serves as the audio output of the system, the power on/off switch, and also as the strap button where you can secure the back of the strap for your instrument. When using a battery to power the system, be sure to unplug the cable when not in use to preserve battery life.
- Page 14 From inside the guitar, insert the endpin assembly through the endblock hole, making sure not to allow the Large Flat Washer and the Locking Washer to fall off. Adjust the Large Hex Nut so the larger threads are about 1⁄16" shy of the outside of the endblock.
- Page 15 Note: When properly installed, the end of the jack will be flush or slightly ahead of the strap nut, so when a plug is inserted, it will snap securely in place. If the end of the jack is recessed too much, the cable plug will not plug in all the way and engage properly, and may even fall out.
- Page 16 ULTRA UPGRADE If you're upgrading your old Amulet system or using another manufacturer's pickups, you'll have an input adapter assembly with jacks for you to plug your pickups into. Plug the input adapter assembly connector into the preamp input (see Page 9 for details on the keyed plug design).

Page 17: Phantom Power
PHANTOM POWER Most modern mixers have 48 volt phantom power built into their microphone preamp channels. This means that you can plug the Amulet Ultra directly into the mic input of your mixer, turn on 48V phantom power and play. Some devices advertise phantom power capabilities, but actually have lower phantom voltages which will not power our system, so be sure to carefully examine any manufacturers literature for any device you are considering for this purpose. - Page 19 Trance Audio's liability for a product found defective is limited to repair or replacement of the unit, at our option. In no event shall Trance Audio be liable for damages based on inconvenience, whether incidental or consequential, loss of use of the unit, loss of time, interrupted operation or commercial loss, or any other consequential damages.
