Front Panel Controls & Connections
1. Guitar In – Plug your guitar in here.
2. Power Switch – Connect the included power cable to your rear panel.
For optimum tube life always power your amp on with your amp set to
STBY.
3. Standby Switch – Allow the amp to warm up for one minute before
setting STBY to ON. This extends the life and performance of your
vacuum tubes. It is not necessary to set the amp to STBY before
setting the Power Switch to its OFF position, but it can be a good
habit, if only to ensure you’ve got it set properly next time you power
up the amp.
4. Master Volume – Sets the overall volume of the amplifier without
having to change your individual channel settings.
5. Channel A & B Controls – DRIVE controls how much “dirt” or
“distortion” you get in your sound. BASS, MID, TREBLE and
PRESENCE controls will interact differently depending on which
VOICING you have selected. REVERB adjusts the channel’s reverb
level, allowing you to switch between channels with different amounts
of reverb. If you don’t want any reverb, simply turn this knob fully
counter-clockwise. VOLUME sets the output level for its channel
only.
6.Channel Select Switch – DT25 features two independent
channels, A & B. When set to A, use the (5A) controls. For B use
the (5B) controls. You can assign unique combinations of Voicing/
Feedback Topology, Amplifier Operating Class and Pentode/
Triode settings for each channel. This provides much more than the
traditional clean/dirty channel configuration. Either channel can be set
up any way you like…even identically, if that’s what you’re looking for. Customization of each channel is not limited to simply changing some
components of the preamp or tone stack - the entire power section
can be reconfigured and switched instantly too. It’s like having two
extremely versatile tube amps in one box!
7. Voicing Switch – This switch determines the flavor of the currently
selected channel’s preamp and tone stack, as well as the Negative
Feedback Loop topology (NFL). NFL has a big impact on tonal
characteristics and the overall “feel” of the amp. Flip the switch up or
down to toggle through settings I through IV. With a single switch your
tone can go from clean to mean. Each voicing is distinct:
I – Puts the NFL in its tightest setting while configuring the Channel
Control’s behavior reminiscent of the great American “Blackface”
amps of the 60’s.
II – Sets the NFL topology to be a little looser than I while the
Channel Control settings are capable of dialing in echoes of
classic British amps.
III – This is the Zero Negative Feedback Loop setting which produces a
very “open” or “dynamic” feeling amp. In this setting, the Channel
Controls are configured for versatility with a distinct “chime-y”
quality.
IV –Setting IV brings the NFL back in and adds a low frequency
resonance that pairs quite well with high gain voicing applied to
the Channel Controls.
8. Class A / Class AB Switch – Class A operation is more dynamic
with greater touch sensitivity. Use Class AB operation for greater
headroom and power. In addition to setting the operating class, this
switch also determines the wattage and bias type:
When set to Class A the amp is running at 10 Watts and cathode
biased. When set to Class AB the amp is running at 25 Watts and fixed
biased.
Try both settings with each voicing to see what sounds best to you.
9. Pentode / Triode Switch – This switch changes the configuration
of the power tubes. Set switch to Pentode to sound clear and
commanding. Triode sounds quieter and rounder with a more vintage
feel.
Rear Panel Controls & Connections
10.Power Cord Receptacle – Plug the included power cable here.
11.Speaker Outs – Connect speakers here using speaker cables only.
You should only use one output (A, B, or C) at a time and never power
the amplifier up without speakers connected. If you want to silence the
speakers, use the Standby switch. The details are as follows:
Output A is for a 4-ohm speaker load. You can either hook up one
4-ohm speaker/cab or two 8-ohm speakers/cabs
Output B is for an 8-ohm speaker load. You can either hook up one
8-ohm speaker/cab or two 16-ohm speakers/cabs.
Output C is for a single 16-ohm speaker load.
12.Cabinet Simulated Direct Out – Provides a transformer-tapped
direct output with cabinet simulation for studio recording or live
performance without mic’ing your amplifier. The ground lift switch can
be used to eliminate hum or buzz. 13.Serial Effect Loop – Use the effect loop to send your audio signal to
external effects processors and stomp boxes such as modulations, delays
& reverbs. Note: Signal path is in series. When using the SEND,
audio will not pass through to the poweramp without a connection
back to the RETURN.
14.Footswitch – Connect a Tip-Ring-Sleeve (TRS) latching, two-button
footswitch for easy access to switching Reverb On and Off (Global)
and switching between Channels A & B.Alternately, connecting a
Tip-Sleeve (TS) latching, single-button footswitch provides easy access
to switching between Channels A & B.
15.Low Volume Mode - If you need to tame your DT25 power section,
set this switch to ON to reduce your the output volume of your DT25.
Now you can set your Master Volume for whisper quiet operation.
16.MIDI – Integrate your DT25 amp into your existing MIDI rig.
17.L6 LINK – is a powerful, proprietary connection developed by Line 6
to enable easy, reliable, one-cable connectivity between various Line 6
products. In the case of the DT25 Series guitar amplifiers and POD HD
(300/400/500) series multi-effects processors, this connection allows
both products to sync and communicate uniquely with each other. L6
LINK passes both audio and control data in a single XLR cable, and
the resulting operation allows users to plug a single cable from their
POD HD family processor into a DT25 series amp and receive many
incredible benefits:
• No additional cables are required to connect a POD HD
(300/400/500) to a DT25 series guitar amplifier.
• Changing Tone settings (for example) on either the POD HD or
DT25 immediately updates the other, with the result that both
units stay perfectly in sync.
• “Edit” a preset on a POD HD by simply turning knobs on the DT25
as one would on any other guitar amp, then save it on the POD HD
to perfectly recall every time the preset is selected.
• This one is crazy cool! Calling up a particular amp model or preset
on the POD HD enables the DT25 to dynamically reconfigure itself
in the analog realm to optimize its components to match the source
amplifier. Change your preset on a POD HD, and the DT25 will
immediately align itself in the analog realm to such things as the
appropriate Class A or AB operation, Biasing method, Feedback
topology, Triode/Pentode power tube configuration and more!
• Automatic sensing allows amps that are daisy-chained via L6 LINK
to operate in a variety of ways, depending on which POD HD is
connected. At a minimum, all POD HD multi-effects support stereo
operation with linked DT25s, and POD HD500 supports up to four
uniquely linked amps making stereo and wet/dry/wet configurations
easily available.
