Instructions for Use:
1. The T3’s output can only be connected to an amplifier or active speakers; it cannot be connected to passive speakers.
2. The T3 is powered by 12V DC; the voltage must not exceed 12V, otherwise the unit will be damaged. The power connector is 5.5 × 2.1, with positive on the inner pin and negative on the outer pin.
3. After connecting the T3 to power, simply set the power switch to the “ON” position to turn it on. If using external trigger startup, set the switch to the “AUTO” position.
4. To use Bluetooth, switch the input to the “BT” position, then search for the Bluetooth name “LSYSAQT3” on your phone and connect.
5. The T3 comes with brand-new, stock vacuum tubes. Before first use, you must insert the tubes into the sockets yourself. Be sure to align the pins correctly and push them in all the way. Do not use excessive force to avoid bending the pins. Vacuum tubes are consumable parts and are not covered by the warranty. Their service life is approximately 1,000 hours, though it may range from 2,000 to 3,000 hours—this is not guaranteed. If the sound quality seems off or there is no sound at all, this indicates the tube has reached the end of its service life and needs to be replaced. Vacuum tubes that have reached the end of their service life are not covered by the warranty; please purchase new tubes on your own.
6. Due to the structural characteristics of vacuum tubes, they require warm-up time to reach full operating condition. After turning on the unit, allow it to run for about ten minutes; once the tubes have warmed up, you can enjoy the beautiful sound.
7. To protect the vacuum tube circuitry and ensure optimal sound performance, the system will undergo a 15-second warm-up after startup. Once the warm-up is complete, the connected power amplifier will automatically turn on.
