5 - Connections Computer connections Two types of USB cables (USB 2.0 or USB 3.0) are included. Use an included USB cable to connect the unit to a computer USB 2.0 or USB 3.0 port according to the computer and OS that you are using. When the USB connection is working, the USB indicator on the front of the unit lights.

CAUTION If you connect this unit to a computer via a USB hub, for example, audio signal dropouts, clicking noises and other interference could occur due to the influence of other USB devices connected to that hub. For this reason, we strongly recommend connecting this unit to a separate USB port. Connecting USB keyboards and mice, however, to the same bus should not be a problem. Audio connections Analog audio signals input into this device from mics, guitars, keyboards and other audio equipment can be converted into digital signals and transmitted to the computer via USB. In addition, by connecting speakers (through an amplifier if not powered) or headphones to this unit, you can monitor audio signals that are input to this unit and output from the computer. CAUTION Before connecting audio equipment, set the unit's 1-8 gain, LINE OUT 1-2 and PHONES 1/2 knobs to their lowest values. Failure to do so could cause sudden loud noises from monitoring equipment, and this could damage the equipment or harm hearing. Microphones 88 Dynamic mics Connect to the IN1-IN8 jacks on the front of the unit. 88 Condenser mics When using a condenser microphone that requires phantom power, connect it to an IN1-IN8 jack and then set the phantom power switch to +48V. CAUTION • Before making connections, turn this unit and all equipment to be connected off (standby). • The phantom power switches set four input channels at a time. Do not set phantom power to +48V when connecting a mic that does not require phantom power. • Set the LINE OUT 1-2 and PHONES 1/2 knobs to their minimum values before changing a phantom power switch setting. Failure to do so could cause sudden loud noises from monitoring equipment, and this could damage equipment or harm hearing. • Do not connect or disconnect mics when the phantom power switch is set to +48V. Doing so could cause a loud noise and might damage this unit and connected equipment. • Set the phantom power switch to +48V only when using a condenser microphone that requires phantom power. Setting phantom power to +48V when a dynamic mic or other mic that does not require it is connected could damage this unit and connected equipment. • When using condenser mics that require phantom power and dynamic mics together, be sure to use balanced dynamic mics. Unbalanced dynamic mics cannot be used when phantom power is enabled. • Supplying phantom power to some ribbon mics will break them. If you are unsure, do not supply phantom power to a ribbon mic. 12 TASCAM US-20x20
