Features
The HT-5R MkII and HT-20R MkII are highly versatile amplifiers suited to a wide
range of playing styles and situations, by including the great tone and innovative
features of the award-winning HT Venue MkII 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 characterised 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 reverb that can be adjusted via the
Reverb control on the front panel.
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.
Two further outputs on the rear, a stereo jack socket and balanced XLR, also allow
the speaker emulated signal(s) to be connected to external devices for practicing,
recording or live use.
