From dspMixFx UR-C
Select the "Guitar Amp Classics" from the "Effect Type", then click "Effect Edit" in the section "Channel Area".

CLEAN

This amp type is optimized for clean tones, effectively simulating the tight brilliance of transistor amplifiers. The tonal character of this amp model provides an ideal platform for recording with multi-effects. It also features built-in chorus and vibrato effects.

1. VOLUME
   Adjusts the amplifier's input level.
2. DISTORTION
   Adjusts the depth of distortion produced.
3. TREBLE/MIDDLE/BASS
   These three controls adjust the amplifier's tonal response in the high, middle, and low frequency ranges.
4. PRESENCE
   Can be adjusted to emphasize the high frequencies and overtones.
5. Cho/OFF/Vib
   Turns the Chorus or Vibrato effect on or off. Set to [Cho] to turn the Chorus effect on, or to [Vib] to turn the Vibrato effect on.
6. SPEED/DEPTH
   These controls adjust the speed and depth of the Vibrato effect when it is on. The SPEED and DEPTH controls only work with the Vibrato effect, and are disengaged when the Cho/OFF/Vib control, above, is set to "Cho" or "OFF."
7. BLEND
   Adjusts the balance between the direct and effect sound.
8. OUTPUT
   Adjusts the final output level.

CRUNCH

This is the amp type to use when you want lightly overdriven crunch tones. The CRUNCH model simulates the type of vintage tube amplifiers that are favored for blues, rock, soul, R&B, and similar styles.

1. Normal/Bright
   Selects a normal or bright tonal character. The [Bright] setting emphasizes the high-frequency overtones.
2. GAIN
   Adjusts the input level applied to the preamp stage. Rotate clockwise to increase the amount of overdrive produced.
3. TREBLE/MIDDLE/BASS
   These three controls adjust the amplifier's tonal response in the high, middle, and low frequency ranges.
4. PRESENCE
   Can be adjusted to emphasize the high frequencies and overtones.
5. OUTPUT
   Adjusts the final output level.

LEAD

The LEAD amp type simulates a high-gain tube amp that is rich in overtones. It is ideally suited to playing lead guitar lines that will project well in an ensemble, but it can also be set up for crisp accompaniment tones as well.

1. High/Low
   Selects the amp output type. The [High] setting simulates a high-output amp, and allows the creation of more distorted tones.
2. GAIN
   Adjusts the input level applied to the preamp stage. Rotate clockwise to increase the amount of distortion produced.
3. MASTER
   Adjusts the output level from the preamp stage.
4. TREBLE/MIDDLE/BASS
   These three controls adjust the amplifier's tonal response in the high, middle, and low frequency ranges.
5. PRESENCE
   Used to emphasize the high frequencies and overtones.
6. OUTPUT
   Adjusts the final output level.
   Using the GAIN, MASTER, and OUTPUT Controls
   The tonal character of the DRIVE and LEAD amp types can be adjusted over a wide range via the GAIN, MASTER, and OUTPUT controls. GAIN adjusts the level of the signal applied to the preamp stage, affecting the amount of distortion produced. MASTER adjusts the output level from the preamp stage that is then fed to power amp stage. The GAIN and MASTER control settings have a large effect on the final sound, and the MASTER control may need to be turned up fairly high in order to drive the power stage sufficiently for optimum tone. The OUTPUT control adjusts the final output level from the amp model without affecting the distortion or tone, and is useful for adjusting the guitar's volume without changing any other aspects of the sound.

DRIVE

The DRIVE amp type provides a selection of distortion sounds that simulate the tonal character of various high gain tube amplifiers. From mildly overdriven crunch to heavy distortion suitable for hard rock, heavy metal, or hardcore styles, this model offers a wide range of sonic capabilities.

1. AMP TYPE
   Six amplifier types are provided. Types 1 and 2 feature relatively mild distortion that allows picking nuances to come through naturally. Types 3 and 4 have more pronounced overtones, resulting in a fat, soft tone.
   Types 5 and 6 deliver wilder, aggressive distortion with a tight attack. The even-numbered amp types have greater presence and range than the odd-numbered types.
2. GAIN
   Adjusts the input level applied to the preamp stage. Rotate clockwise to increase the amount of distortion produced.
3. MASTER
   Adjusts the output level from the preamp stage.
4. TREBLE/MIDDLE/BASS
   These three controls adjust the amplifier's tonal response in the high, middle, and low frequency ranges.
5. PRESENCE
   Can be adjusted to emphasize the high frequencies and overtones.
6. OUTPUT
   Adjusts the final output level.

Monitor Mode

UR24C has two different monitoring configurations: monitor mode DAW and monitor mode DJ. Monitor mode DAW is used for producing music with a DAW such as Cubase. The monitor mode DJ is convenient for music performance use with DJ software.

How to switch the monitor mode

The monitor mode can be switched on the "Setup Window" of dspMixFX UR-C.

In monitor mode DAW, the POWER indicator of the front panel and the monitor mode icon of the dspMixFx UR-C light in white, and light in red in monitor mode DJ.

How to use the slide switch and MIX knob

Monitor mode DAW

After the level of the input signal from the [MIC/LINE 1/2] jacks and the output signal as UR24C Mix L/R from DAW is adjusted with the [MIX] knob, the signal is output to the [LINE OUTPUT 1L/R] jacks.
This signal is called OUTPUT 1. Turn the [MIX] knob to the [DAW] side if the input volume is high and to the [INPUT] side if the input volume is low. When the knob is turned fully to the [DAW] side, only the input sound from DAW can be heard.
The output signal from DAW as UR24C Output 2 L/R outputs directly to [LINE OUTPUT 2L/R] jacks. This signal is called OUTPUT 2.
When the slide switch is set to [OUTPUT 1], the OUTPUT 1 signal is output to the headphones. When the switch is set to [OUTPUT 2], the OUTPUT 2 signal is output.

Monitor mode DJ

Set the master output for DJ application to UR24C Mix L/ R, and the monitor output to UR24C Output 2 L/R.
After adjusting the level of the input signal to [MIC/LINE 1/ 2] jacks and the master output signal of DJ application in dspMixFX UR-C, the signal is output to the [MAIN OUTPUT L/R] jacks and [LINE OUTPUT 1L/R] jacks. The signal is called MASTER.
The monitor output of the DJ application is output directly to the [LINE OUTPUT 2L/R] jacks. This is called CUE.
When the slide switch is set to [SPLIT], the monoral master sound is output from the right side of the headphones, and the monoral cue sound is output from the left.
Use the [MIX] knob to adjust the left and right volume balance.
When the slide switch is set to [STEREO], the stereo master and cue sound is mixed and is output to both the left and right.
Use the [MIX] knob to adjust the mix balance.
NOTE
In monitor mode DJ, you can adjust the balance of the input signal to [MIC/LINE 1/2] jacks and the output signal from software such as a DAW only by using dspMixFx UR-C.
