RedPlate BlackMagic Operations Guide
3
Gain
–This control sets the amount of break up character you desire in your tone.
Typical
setting is around
7 o’clock for lower gain tones and around 3 o’clock for high gain tones but
experimentation is encouraged.
Gain2
– Like Gain (above) This control lets you set an alternate amount of break up character
you desire in your tone.
This control is deactivated when rotated all the way counter clockwise.
Active at all other settings, it can be switched on or off with the Gain2 button on the footswitch.
Treble Control
–
Adjusts the balance of high and low frequencies, fatter treble when pulled.
Middle Control
–
Controls the amount of Midrange frequencies, somewhat interactive with
the Bass Control.
Bass Control
– Sets the amount of low end. Can be rotated to zero where it clicks off for a full
tone stack lift (Tone Controls are Bypassed).
MASTER SECTION
Master1 Volume
– This is an active control and actually adds gain at the higher settings. The
cleanest tones are achieved at settings below
2 o’clock.
Master2 Control
– When engaged with the footswitch it is Identical to Master1
Control. Useful
for setting a solo volume.
Standby/Operate Switch
– This switch allows the tubes to warm up before operating the
amplifier. Wait 1 minute after power on to move it up to the operate position. For improved tube life
and performance do not leave the amplifier in Standby position for longer than 20 minutes (better to
just leave it in operate mode during performance intermissions).
REAR PANEL SECTION
IEC Module
– contains the main power switch, power cord inlet connector and the fuse drawer
which doubles as the voltage selector on export models. To access the fuse(s) use a small flat
blade screwdriver in the notch at the bottom of the power cord inlet connector, the drawer snaps
out in a rearward direction. The BlackMagic can accept both the larger (3AG footprint) or smaller
European (5mm X 20mm) fuses. A time delay variety (SLO-BLO) is recommended.
Export version
is identical , observe back panel recommended fuse value.
100 WATT / 50 WATT Switch
– This switch changes the output tube by lifting the center pair of
output tubes (V7 & V8) enough to be irrelevant. The impedance selector does not have to be
changed in 50 watt mode.
