4 ABOUT THE POWER SUPPLY: The TX15 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 in 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 at least 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 TX15 must be fully charged before operating the amplifier for the first time. The amplifier leaves our factory with a 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 #14, page 6) doesn’t illuminate, the battery might be beyond recharging. (The TX15 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: SLM Electronics 1901 Congressional Drive St. Louis, MO 63146 1-800-738-PARTS (7563) CAUTION! The TX15 contains a sealed, rechargeable, lead-acid battery. Improper disposal of battery or replace- ment with any other type may cause leakage, explosion, and/or injury.

5 1. INPUT 1: Use this jack to connect a low or a high impedance micro- phone to the amplifier by means of a shielded signal cable. 2. VOLUME 1: Use this control to adjust the level of the signal con- nected to the Input 1 jack (#1). 3. INPUT 2: Use this jack to con- nect an instrument or a high impedance microphone to the amplifier by means of a shielded instrument or signal cable. 4. VOLUME 2: Use this control to adjust the level of the signal con- nected to the Input 2 jack (#3). 5. LOW: Use this control to adjust the level of the low frequencies for both inputs. 6. LOW MID: Use this control to adjust the level of the lower-middle frequencies for both inputs. 7. HIGH MID: Use this control to adjust the level of the upper-mid- dle frequencies for both inputs. 8. HIGH: Use this control to adjust the level of the high frequencies for both inputs. 9. CD INPUT: Use these jacks to connect the output of a CD player, a tape player, a rhythm machine or any other similar source to the amplifier by means of a shielded signal cable. These jacks are con- nected in parallel – a stereo signal should be connected to both jacks (the left channel to one jack, the right channel to the other), while a mono signal may be connected to either jack. 10. HEADPHONES: Use this jack to connect a pair of stereo head- phones to the amplifier. The inter- nal speaker is disconnected when the headphones jack is used. 11. LED: When the power switch is on and the battery is fully charged, this LED illuminates yellow. The LED illuminates red when the bat- tery needs recharging. 12. POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch depressed). THE FRONT PANEL:
