Laney LH50 Operating Instructions Manual page 11

7 CHANNEL SWITCH: Switch in to enable the 'Drive' channel. (This switch must be in the disengaged position in order for
the drive to be switched remotely via a foot switch.)
8
DRIVE LED: This led will illuminate when the Drive channel is activated with the Drive switch (8) or an optional Laney FS2
remote footswitch.
9 DRIVE: Sets the level of tube preamplifier drive or how dirty your sound is. This control should be used in conjunction with
the Drive Volume (12) Setting low levels of gain with high levels of volume will give a clean preamplifier sound with tube
output stage overdrive. Setting a medium drive level and medium Drive Volume will give a nice crisp bluesy tone, again with
the ability to drive the output stage at higher Drive Volume settings. Setting a high level on the Drive control and a low
setting on the Drive Volume will give you a punchy hard rock tone, with the ability to again drive the output tubes at higher
Drive volume settings. Having set the Drive and Drive Volume controls to your desired sound try backing off your guitar
volume and tone controls for lots of other cool sounds. Good tube amplifiers have the unique ability to produce a wide
range of sounds by using only your guitar controls, playing weight and style.
10
MODERN: The modern switch applies a degree of compression & bass lift to the signal, providing massive smooth sustain.
11
BASS, MIDDLE, TREBLE: These are a traditional set of passive tone controls for the Drive channel and work in a similar
way as those for the clean channel, except that they operate post distortion giving a wider range of distorted tone.
12 DRIVE VOL: Sets how loud the 'Drive' channel is. It is useful to experiment with drive levels and drive volumes. If you
want a very open, warm and semi overdriven sound try reducing the amount of drive and increasing the drive volume. This
reduces pre-amp gain but pushes the power amp section and makes it work harder giving you a very desirable level of power
amp distortion which is a very pleasing "retro" style sound.
13
TONE: The tone control works in a similar fashion to the Tone control you probably have on your guitar except that it
uniquely works at the other end of the amplification chain. This has the ability to not only control the overall top end
response but also reduce upper end harmonics on the output stage and preamplifier overdrive sounds. This will give you
bright cutting sounds at high settings and smooth rounded sounds at lower settings. (Midway (5) is a good starting point)
14
REVERB: Controls how loud the Digital Reverb sounds.
15 POWER LED: This led will be lit when the amplifier is switched on. (Always switch off and disconnect the power
cord when not in use)
16 STANDBY: Disconnects the main HT voltage from the tubes but keeps the tubes warm so that they are ready to go
instantly. Switch off for short breaks when you don't want to wait for the tubes to warm up again.
17 POWER: Main power switch for the unit. Tube amplifiers take between 30 seconds and 2 minutes to warm up and be ready
to play after switching on, this is normal. Use in conjunction with the standby switch.
