Do not place any objects filled with liquids, such as vases, on the apparatus. Do not install this apparatus in a confined space such as a book case or similar unit. The apparatus draws nominal non-operating power from the AC outlet with its POWER or STANDBY/ON switch not in the ON position. The apparatus should be located close enough to the AC outlet so that you can easily grasp the power cord plug at any time. The mains plug is used as the disconnect device, the disconnect device shall remain readily operable. Products with Class I construction are equipped with a power supply cord that has a 3-prong grounding plug. The cord of such a product must be plugged into an AC outlet that has a protective grounding connection. If the product uses batteries (including a battery pack or installed batteries), they should not be exposed to sunshine, fire or excessive heat. CAUTION for products that use replaceable lithium batteries: there is danger of explosion if a battery is replaced with an incorrect type of battery. Replace only with the same or equivalent type. Caution should be taken when using earphones or headphones with the product because excessive sound pressure (volume) from earphones or head- phones can cause hearing loss. If you are experiencing problems with this product, contact TEAC for a service referral. Do not use the product until it has been repaired.

Precautions and notes for placement and use The operating temperature should be between 5C and 35C (41F and 95F). Make sure that the unit is mounted in a level position for correct operation. Do not place any object on the unit for heat dissipation. Avoid installing this unit on top of any heat-generating electrical device such as a power amplifier. Beware of condensation If the unit is moved from a cold to a warm place, or used after a sudden temperature change, there is a danger of condensation; vapor in the air could condense on the internal mechanism, making correct operation impossible. To prevent this, or if this occurs, let the player sit for one or two hours at the new room temperature before using. Cleaning the unit To clean the unit, wipe it gently with a soft dry cloth. Do not wipe with chemical cleaning cloths, benzene, paint thinner, ethyl alcohol or other chemical agents to clean the unit as they could damage the surface. 1 Introduction TASCAM US-2000 7 2 Names and Functions of Parts NOTE Turn all the way to the left to minimize the input level or all the way to the right to maximize the input level. q MONITOR switches Use these switches to set whether or not adjacent inputs 1-2, 3-4, 5-6, 7-8 are monitored in mono or as stereo pairs with odd-numbered channels (1, 3, 5, 7) on the left and even-numbered channels (2, 4, 6, 8) on the right. w +48V switches Use these switches to set whether or not +48 V phantom power is provided to the mic input jacks in pairs (1-2, 3-4, 5-6, 7-8).
