Randall RT2/50 Owner's Manual - page 4
Front panel Features and controls:
Channel switching:
The RT2/50 has a three selection from panel switching control. The front button selects between Channel 1(Selection 1), Channel
2(Selection 2), and bypass mode (Selection 3). Each channel can be MIDI programmed to the desired module or preamp channel.
To select and save the channel you want to use, simply set to the desired channel, push and hold the channel button for 2 seconds
and release. The bypass mode can also be programmed to quickly eliminate any noise when finishing a tune. Program the bypass
mode the same as you would Channel 1 or 2.
Volume controls:
The front panel features two separate volume controls, one for each channel. These knobs control the level of output for each
channel.
Density controls:
Each channel as features a density control knob. This knob boosts the amount of overall low end in your guitar tone. This is an
additional low end EQ control that should be set to your desired liking.
Presence controls:
A Presence control can also be found on each channel. This knob boosts the amount of overall hi-end and sparkle in your tone.
This is an additional hi-end EQ control, that should be set to your desired liking.
Tube Bias Section:
Very cool specialized feature. This section allows you quickly and easily change or replace your power tubes, and correctly bias the
tubes. Please refer to the Bias section, later in this manual. Please refer to pages 5 & 6 for details functions and uses.
Play/Standby:
This switch is mainly used to protect and save the life of your power tubes. Once the power has been turned on, this switch puts
your amplifier in standby or play mode. Please switch to standby position when not using the amp for a short period of time, like set
breaks, to save the life of your power tubes. Select the play position when ready to use the amplifier. Always switch to Standby
position before turning off the power switch. It is recommended to turn on the main power switch, and allow the amplifier to warm
up at least 30 seconds before turning this switch to play mode.
Power Switch:
This is the main AC power switch. The switch turns the unit on or off for the amplifier.
IMPORTANT: Make sure the amp is in Standby mode, anytime your turning the power on and off.
