Overview

The revolutionary Line 6 DT50™ & DT25™ are not only full-featured tube amplifiers, but also offer numerous circuitry parameters to customize their sound and feel. In this guide we’ll cover how you can utilize a standard external MIDI controller device to access this multitude of DT amp options for maximum tweakability. This effectively allows you to fully customize your DT amplifier so that each of its Voicing switch settings (I, II, III & IV) for both Channel A and Channel B recall your own customized preamp and power amp configurations.

You may first want to review the Pilot’s Guide that came with your DT Series amplifier to be familiar with all its features - available in PDF form at www.line6.com/support/manuals/.

Note: This Guide covers DT50 & DT25 amplifiers with Flash Memory version 2.0 (or later) installed. Use the Line 6 Monkey software to download and apply the latest updates for your DT Series amp - available free at http://line6.com/software/.

MIDI or L6 LINK™?

In case you are asking yourself this question regarding how to best access your DT amp settings...

Line 6 POD® HD Pro, HD500, HD300 & HD400 devices include the unique L6 LINK functionality, which allows complete integration and control with DT amplifiers. If you are wanting control over your DT amp in a live setting, then using a POD HD with a L6 LINK connection to the DT amp is the way to go. This allows 2-way communication, control over amp models, amp parameters, effects, knob settings, volume levels and more. The ability to store all these settings and recall Presets makes L6 LINK the preferred choice for real-time performance control.

The DT amps’ MIDI implementation is offered primarily for customization of your DT amp and to access “hidden” settings not found on the amp’s front panel. Once you send MIDI CC messages to your DT amp, your changes are retained on the amp. For example, if you set your DT amp to Channel A and the Voicing switch position “I,” you can then send MIDI CC messages to determine the specific preamp and power amp configuration - which will then be recalled when you set the DT amp to Channel A, Topology I. You’ll see more details about this functionality in the following sections.

Note: For more info about L6 LINK, please see the POD HD Advanced Guide and L6 LINK Connectivity Guide PDFs, available at http://line6. com/support/manuals/.

Overview

MIDI Connectivity

Your DT Series amplifier will respond to specific MIDI CC messages to configure preamp, power amp, switch amp channels, control tone knobs, etc. (See the MIDI CC tables in the following chapter for the list of specific parameters & commands.) You can use any manufacturer’s external MIDI controller device that is capable of configuring MIDI CC commands and values, and that includes a standard 5-pin MIDI OUT jack. Connect a standard MIDI cable from the controller device’s MIDI OUT to the 5-pin MIDI IN port on the back of your DT Series amp. There is no other configuration of the DT amp necessary for MIDI control - it will respond to valid MIDI CC messages on MIDI Channel 1.

Got a POD HD500 or POD HD Pro? These devices are capable of functioning as MIDI controllers, where you can configure the specific MIDI CC messages to be sent from its footswitches & pedals. See the POD HD Advanced Guide PDFs at http://line6.com/support/manuals.

Or, if you have an Apple® iPhone®, iPod touch® or iPad®*... Check out the Line 6 MIDI Mobilizer™ II, the mobile app & MIDI interface that lets you take control of MIDI devices anywhere! See http://line6.com/midimobilizer/mmii/ for details.

DT Amplifier Factory Reset

As mentioned in the above sections, when customizing any settings via MIDI, your changes remain “saved” internally on the DT amplifier. This includes changes made to the preamp and power amp per Voicing switch value, Reverb and more. To return all settings back their factory default state, you’ll need to perform a “Reset” of the DT amp. To perform the Reset, start with the DT amplifier powered “Off,” then simultaneously hold the Voicing toggle switch DOWN and the Pentode/Triode toggle switch UP while powering the amp “On.” Continue to hold these toggle switches in this position until you see the Voicing “I” indicator light up (this takes about 15 seconds). The DT factory default settings are then fully restored and your DT amp is ready to play.

Hold the Voicing switch Down

Turn the Power On with other switches held

Hold the Pentode/Triode switch Up
