BT220 Congratulations! You are now the proud owner of the Crate BT220 Bass Amplifier. The BT220 features two different channels: a distortion channel, featuring Crate’s exclusive Shape control for quick and easy access to the tone you need, and a clean channel with a four-band rotary EQ.
BT220 Bass Amplifier The Front Panel: 1. INPUT: Use this 1/4” jack to connect your bass to the amplifier by means of a shielded instrument cable. 2. -15dB/0dB: Use this switch to match the output signal level of your instrument to the amplifier. If your instru- ment has standard pickups, setting the switch to the 0dB position (switch in the out position) should yield the best results.
BT220 The Front Panel: 17. HEADPHONES: Use this jack to listen to the amplifier through a pair of stereo headphones. The internal speaker is disconnected when the headphones jack is used. To avoid possible damage to your hearing, do not use headphones for extended periods of time at extremely loud listening levels.
