Thermal Overload Protection. The transmit relay in the amplifier is disabled if
excessive heatsink temperatures are reached.
Compact size. The ALS-600 weighs only 12.5 pounds and measures 6"H x 9.5"W x
12"D.
Remote Amplifier Operation. The ALS-600 amplifier can be tucked out of the way
when used with the optional ALS-500RC Remote Control Head. The ALS-500RC
provides band switching, transmit and load fault indicators, output power monitoring, and
fault re-setting in a compact control and display unit.
Automatic Transceiver Frequency Tracking. The optional ARI-500 Automatic Band
Switch unit interfaces frequency band information for most transceivers to the ALS-600.
So as you change frequency bands on your transceiver, the ALS-600 automatically
follows these band changes. The ARI-500 may be configured for automatic fault re-
setting of the ALS-600 if desired. These features make the ARI-500 particularly
convenient for contest operations. The ARI-500 Automatic Band Switch includes an
input for the ALS-500RC Remote Control Head, so both may be used simultaneously if
desired.
