About the Power Supply | Crate Amplifiers TXB50 guide

ABOUT THE POWER SUPPLY:

The TXB50 uses a sealed lead-acid 12-volt battery as its internal power source. Unlike ni-cad batteries, this battery has no “memory” – it can be fully recharged at any time, without damage to the battery.

When fully charged, the LED next to the power switch will illuminate yellow with the switch at the on position. The LED will change to red when the battery is low and needs recharging. When this happens, turn the amp off, connect the 15-volt charger to the charger jack and plug it in to an AC outlet. The LED near the charger jack will illuminate red while the amp is charging and goes out when the amp is fully charged. The battery fully recharges within 6 hours, providing up to 8 hours of use at low levels, about 4 hours of use at moderate levels, and about 2 hours of use at continuous full power (sine wave). The battery is rated for up to 1000 charging cycles. (The charger can also function as an AC power supply.)

The battery inside the TXB50 must be fully charged before operating the amplifier for the first time. The amplifier leaves our factory with a fully charged battery. However, the battery may lose some of its charge in transit.

NOTE: If the battery is drained too low, the Power LED will go out. This indicates an exhausted battery – one which may not take a charge. If this happens, turn the amp off, connect the 15-volt charger to the charger jack and plug it in. If the Charger LED (see #17, page 8) doesn’t illuminate, the battery might be beyond recharging. (The TXB50 uses a “smart” charging circuit and will not allow you to charge a defective battery.) If the battery is serviceable, the LED will illuminate once the battery reaches 10 volts – leave the charger plugged in and let the bat- tery fully recharge. If the LED never illuminates, the battery may need replacing. Contact Crate’s service department:
