RedPlate RedLine Operations Guide
2
Input Jack
– Typical High impedance input to the amplifier. Designed to be “Pedal Friendly”.
Volume
–
Typical setting is between 10 and
1 o’clock but experimentation is encouraged.
Gain
–
Typical setting is between 10 and
1 o’clock but experimentation is encouraged.
The combination of Volume and Gain lets you adjust the character of the channel at various
volume levels for consistency of tone and character in both small and large venue sizes.
Treble Control
-
Adjusts highs.
Middle Control
–
Controls the amount of Midrange frequencies, somewhat interactive with
the Bass Control..
Bass Control
– Sets the amount of low end,
somewhat interactive with the Middle Control.
Presence Control
– The presence circuit uses global negative feedback to remove low
frequencies which frees up bandwidth for more midrange and highs.
Master2 Volume
– Only used when footswitch is connected. This is an active control and
actually adds gain at the higher settings. The cleanest tones are achieved at settings below 2
o’clock.
Master1 Volume
– This is the default Master, it is an active control and actually adds gain at
the higher settings. The cleanest tones are achieved at settings below
2 o’clock.
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
SEND and RETURN Jacks
– The send jack connects to the input of an external effects device
and the return jack connects to the output of an external effects device. The return jack interrupts
the signal path so the external effects unit must mix the wet and dry signals.
Footswitch Jack
- This is a standard
¼” for footswitch connection.
Impedance Selector Ω
- Set this to the total impedance of all attached speakers.
Speaker Jacks
– The MAIN and EXT jacks are wired in parallel. The MAIN jack must be used
first because it has a protection device. ALWAYS HAVE A SPEAKER CONNECTED TO AVOID
PERMANENT AMPLIFIER AND OUTPUT TUBE DAMAGE.
LINE OUT
– A line level signal jack derived from the speaker output which contains the whole
tone of the amplifier.
Bias adjustment and bias test point
– Allows external access for bias adjustment (see bias
procedure in the
Maintenance
section).
IEC Module
– contains the main power switch, power cord inlet connector and the fuse drawer
which contains both the MAINS as well as the H.T. fuses. 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 RedLine can accept both the larger (3AG footprint) or smaller
European (5mm X 20mm) fuses. A time delay variety (SLO-BLO) is recommended for the MAINS
fuse. Right side fuse is a 1 amp H.T. fuse, this fuse is an extra layer of protection for the output
transformer and power transformer. If this fuse blows it generally indicates an output tube failure.
The left side fuse is the MAINS fuse,
observe back panel recommended fuse value.
Bias adjustment and bias test point
– Allows external access for bias adjustment (see bias
procedure in the
Maintenance
section).
