Laney L20T-212 - Manual (Page 6)

POWER INLET SOCKET: Connect to your power source. Make sure the specified voltage is correct for your
country!
POWER FUSE: This drawer contains the main safety fuse for the unit. The fuse protects the AC power to the
amplifier. USE ONLY THE CORRECT SIZE AND RATING OF FUSE AS SPECIFIED ON THE PANEL. If a fuse blows or
fails and a replacement of the same size and rating is installed and it in turn blows, the amplifier has suffered a
malfunction internally and needs immediate service from a qualified technician. DO NOT TRY USING A FUSE OF
HIGHER RATING. Using a fuse that is too large in current rating may cause serious, irreparable damage to the amplifier
and presents a serious fire hazard. The mains fuse ratings are detailed in the specs section at the rear of this manual
POWER: Main power switch for unit.
HT FUSE: This fuse protects the DC power to the tubes within the amplifier. USE ONLY THE CORRECT SIZE AND
RATING FUSE AS SPECIFIED ON THE PANEL. If a fuse blows or fails and a replacement of the same size and rating is
installed and it in turn blows, the amplifier has suffered a malfunction, at this point check the output tubes and replace
faulty ones if required. Should tubes not be the problem the amplifier should be checked out by a qualified technician.
Do not try using a fuse of greater value. Using a fuse that is too large in current rating may cause serious, irreparable
damage to the amplifier. Fuses are designed to protect, do not take chances.
SERIAL NO: Displays the model and serial number of the unit.
EXTENSION CABINET: If the onboard loudspeaker jack is removed, a 4-16 ohm cabinet can be connected directly
to these sockets. Use only one impedance selection at once. Please note mismatched impedance will reduce the
amplifiers performance and in some cases may cause damage to your amplifier.
