Features
The HT-5R MK III and HT-20R MK III are highly versatile amplifiers suited to a wide range of playing styles and situations, by including the great tone and innovative features of the HT Venue MK III range.
The Clean Channel has two voices; one based on a classic American circuit and the other based on a classic British tone. The Voice switch reconfigures the preamp voicing, EQ and valve gain structure, as well as the power amplifier damping. This produces a clean, bright and tight but solid bass response for the American tone and a highly responsive 'chime' with looser bottom for the British tone that can be pushed into a midrange overdrive when driven hard. The Voice setting can also be selected via footswitch.
These amplifiers also have two voices on the Overdrive Channel, which share a common EQ section. These two voices provide a broad palette of overdriven tones.
As with the Clean Channel, each of these voices can also be selected by footswitch.
The Overdrive voices are characterized by a tone which is high in gain, but avoids any of the detached top-end 'fizz' often found in other designs. This is a result of unique preamplifier and power amplifier shaping techniques, which also benefit the player in the way the overdrives clean up beautifully as the guitar volume is reduced. Even at the most extreme settings, the Overdrive voices remain natural sounding.
The patented ISF (Infinite Shape Feature) control is unique to Blackstar Amplification and represents a major step forward in tone shaping flexibility. The ISF control shifts the response of the three-control tone stack between, a US type response at one end, and at the other, a UK type response. Importantly, in between the two extremes lie an infinite number of alternative tone choices that would be otherwise unavailable.
The amplifier features naturally sounding digital reverber that can be adjusted via the Reverb control on the front panel.
The reverb decay times can also be adjusted differently for each channel by connecting via USB to our proprietary Architect software.
A Power switch is provided on the front panel to switch the amplifier between full power and 10% power. This means that the full tonal depth of the power valve stage can be enjoyed at any volume, retaining the distinctive sound of power valves working hard.
A USB connector allows for sending a speaker emulated output into a computer for recording purposes.
It also enables the connection to the previously mentioned Architect software for deep editing of not only the rever, but also extensive control of CabRig parameters for power amp/speaker/cabinet/mic/room simulations from the USB, balanced DI and stereo headphones/line outputs, for practicing, recording and live use.
Front Panel
1. Input
Plug your guitar in here. Always use a good quality screened guitar lead.
If there is no connection to the input, the power amp is automatically set to Standby Mode.
Clean Channel
2. Clean Volume
This controls the volume of the Clean Channel. Turning it clockwise increases the volume. At extreme clockwise settings the preamplifier will start to overdrive, particularly in the 'British' mode.
3. Clean Voice Switch
This switch selects between the two clean voices. With the switch up, the 'American' setting is very clean and bright but with a solid and tight low end. When this Voice is selected, the Voice LED is unlit. With the switch down, the 'British' setting has a looser bass response with warmer mid-range and is very sensitive to the output level of the guitar and the player's dynamics. When this Voice is selected, the white Voice LED is lit. The EQ voicing and valve gain structure is completely reconfigured between each voice.
4. Tone
This is a dual control that effectively adjusts the treble and bass for the Clean Channel at the same time. Fully counter clockwise (CCW) will be darker and bassy in character. Rotating the control clockwise (CW) will progressively brighten the sound and thin the bass.
OD (Overdrive) Channel
5. OD Select Switch
Press this switch down to select the OD Channel. When the red LED is on, the OD Channel is selected. When the red LED is off, the Clean Channel is selected.
6. OD Gain
The OD Gain control adjusts the amount of this Channel's overdrive or distortion. Low settings (anti-clockwise) will deliver a clean sound on the edge of break-up. As the Gain control is increased clockwise the sound will become more overdriven, moving through crunch tones until, at its maximum position, a full distorted tone is reached.
7. OD Voice Switch
The switch selects between the two voices of the OD Channel. When the small white LED is unit, this channel has a 'classic' but 'hot-rodded' overdrive, with medium power amp damping. With the white LED lit the overdrive sound has a more 'modern' voicing that includes a strong mid-emphasised pre-overdrive boost, as well as a looser, more aggressive sound due to reduced power amp damping.
8.QDVolume
This control adjusts the overall volume of the OD Channel. Turning it clockwise increases the volume.
9. Bass
The Bass control adjusts the amount of low-end frequencies in your tone. This amp has an advanced tone shaping circuit which allows the tone to be varied from light and cutting when counter clockwise, to warm and trumping when fully clockwise.
10.Middle
The Middle control adjusts the amount of middle frequencies in your tone. The middle frequencies are particularly important in setting the amount of 'body' your tone has. With the Middle control set to its minimum position (fully counter clockwise) the sound will be aggressive and scooped, a tone ideal for aggressive rhythm playing. As the Middle control is increased (clockwise) the amount of 'body' is increased, which is more suitable for sustained lead guitar tones.
11.Treble
The Treble control allows exact adjustment of the treble frequencies within the sound. At low settings (counter clockwise) the sound will be warm and darker in character. As the Treble control is increased (clockwise) the sound will become brighter. At the maximum settings the sound will be aggressive and cutting.
12.ISF (Infinite Shape Feature)
The patented ISF control works in conjunction with the Bass, Middle and Treble controls. It allows you to choose the exact tonal signature you prefer. Fully counter clockwise has a more American characteristic with a tight bottom-end and more aggressive middle, and fully clockwise has a British characteristic which is more 'woody' and less aggressive.
Unlike conventional 'contour' controls and parametric equalisation systems, the Bass, Middle and Treble controls remain interactive with each other just like in a traditional guitar amplifier tone stack. This leads to a very familiar, musical response.
Master
13.Reverb
The Reverb control sets the overall level of the reverb effect. With the control fully counter clockwise there will be no reverb. Turning the control clockwise will increase the amount of reverb.
Reverb decay times can be adjusted for the Clean and OD channels by connecting to our Architect deep-editing software.
14. Volume (HT-20R/RH MK III ONLY)
This controls the overall volume of your amplifier. Turning it clockwise increases the volume.
15. Power Switch
This switch allows the reduction of the output stage from full power down to 10% power. This means the full tonal depth of the valve power amplifier can be enjoyed at lower volumes, therefore making the HT MK III Ideal for recording, smaller gigs and home practice use. Working in conjunction with the power amplifier voltages, this method of power reduction suffers none of the loss in tone of other power reduction systems.
16. Power Indicator Light
The LED will be illuminated when the amplifier is switched on.
17. Power
This switch is used to turn the amplifier on and off.
NOTE: There is no standby switch on these amplifiers. The valves will warm up as normal and the amplifier will automatically switch to standby mode if either the Input or Speaker Output jacks are not in use.
Rear Panel
1.Mains Fuse
The value of the Mains Fuse is specified on the rear panel. Never use a fuse of the incorrect value or attempt to bypass it.
2. Mains Input
The supplied detachable mains lead is connected here. The lead should only be connected to a power outlet that is compatible with the voltage, power and frequency requirements stated on the rear panel. If in doubt get advice from a qualified technician.
3. H.T. Fuse
The value of the H.T. Fuse is specified on the rear panel. Never use a fuse of the incorrect value or attempt to bypass it.
4. Speaker Outputs
The output marked "1x16 Ohm" is for the connection of a single 16 Ohm extension speaker cabinet.
The outputs marked '1x8 Ohm or 2x16 Ohm' are for the connection of either a single 8 Ohm extension cabinet or two 16 Ohm cabinets.
If no connection is made to any speaker outputs, the power amp is automatically set to Standby mode. Unlike most other valve amplifiers, this is safe to do.
1x16 Ohm output 1x8 Ohm or 2x16 Ohm' outputs
| Internal 16 Ohm combo speaker | X | X | ||
| Internal 16 Ohm combo speaker plus one 16 Ohm extension cab | X | ✓ | ✓ | |
| One 16 Ohm extension cabinet | ✓ | X | ||
| Two 16 Ohm extension cabinets | X | ✓ | ✓ | |
| Single 8 Ohm extension cabinet | X | ✓ | X |
WARNING: The output marked '1x16 Ohm' should never be used at the same time as any of the outputs marked '1x8 Ohm or 2x16 Ohm'. Failure to correctly match the impedance of the amplifier and speakers could damage the amplifier.
5. CabRig Output - Mono Balanced XLR socket
This output provides a balanced, low impedance connection to a recording device, stage box or mixing desk using a standard XLR cable.
6. CabRig Output - Stereo Line Out / Phones socket
This output provides a stereo un-balanced connection to a recording device or mixing desk. Always use a good quality screened TRS lead. The stereo jack socket also accommodates connection of headphones, allowing you to practice silently.
NOTE: Both the XLR and Stereo Emulated outputs remain active even when in Standby mode. This allows for silent recording or practice when the amplifier is not connected to a speaker.
7. CabRig Switch
The switch enables you to instantly select between one of the three stored CabRig patches. This will apply to the XLR, Line Out / Phones and the relevant USB output CabRig patches can be edited using Architect software.
Learn more about Architect here: https://blackstaramps.com/architect/
8. Line In
This is a stereo mini jack input. Connect the output of your audio device here and adjust the player's volume to match that of your guitar to enable you to play along.
NOTE: This connection is stereo, and will remain stereo from the Emulated Output Stereo Jack Socket (6). All others outputs will mix the incoming stereo signal and output a mono version.
9. Effects Loop Level
The Effects Loop Level switch sets the effects loop to either +4dBV / - 10dBV , which enables you to use it with either professional equipment ( +4dBV setting), or with guitar level effects such as effects pedals (-10dBV setting).
10. Effects Loop Return
Connect the (mono) output of an external effects unit here.
11. Effects Loop Send
Connect the (mono) input of an external effects unit here.
12. Footswitch
The latching 2-way footswitch can be connected here. The footswitch will enable the selection of the Clean and Overdrive channels, and the two voices on each Channel.
NOTE: Using a footswitch will disable the front panel channel and voice switches. Therefore, full control via the footswitch is granted irrespective of how the amplifier is set.
EXTERNAL SWITCHING: This can also be used by people who wish to control the main features of the amp using an external switching device that connects via the TRS connection of the socket.
The following external conditions will switch the channels and voices as follows:
TIP RING CHANNEL VOICE
Closed Closed Clean Voice 1
