Precautions for placement and use

The US-1641 may be used in most areas, but to maintain top performance, and prolong operating life, observe the following notes, precautions and environmental conditions:
Avoid exposing it to extremes of temperature and
humidity and avoid mechanical shocks and vibration. Keep the unit away from strong magnetic fields (TV
sets, computer monitors, large electric motors, etc.). The nominal temperature should be between 5°C and
35°C (41°F and 95°F).
Please contact your TASCAM supplier if any of these accessories are missing.
We recommend that you keep the original box and packing materials for transportation of this unit.
This typeface is used to designate on-screen controllers
or buttons: Cancel Except above, this typeface is used to designate any text
displayed by the software: New project
Relative humidity should be 30 to 90 percent.
As the unit may become hot during operation, always
leave sufficient space above the unit for ventilation. Do not install this unit in a confined space such as a book­case, and do not put anything on top of the unit. Avoid installing this unit on top of any heat-generating
electrical device such as a power amplifier. The voltage supplied to the unit should match the volt-
age as printed on the rear panel. If you are in any doubt regarding this matter, consult an electrician.

IMPORTANT SAFETY INSTRUCTIONS

Beware of condensation

1 – Introduction
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.

Front Panel

1 POWER switch and indicator Turns the power to
the unit on or off. The POWER indicator lights up red when the power is on.
2 USB indicator Lights up green to indicate a valid
USB connection to the host computer.
3 PHANTOM [1-4/5-8] switches Turn on the +48V
phantom power supplied to the MIC IN [1-8] jacks.
Each switch turns on the phantom power for four input channels as a group. The phantom power is on when the switches are pushed in.
Turn this switch on only if you are using condenser microphones that require phantom power.
Do not connect or disconnect microphones from the US-1641 while phantom power is on.
Never supply phantom power to unbalanced dynamic microphones.
Some ribbon microphones can be damaged by phantom power. If you are not sure about your ribbon microphone, do not supply phantom power to the ribbon microphone.
4 MIC IN [1-8] jacks These are XLR balanced analog
mic input jacks. Use the Gain knobs to adjust the input gain level.
The wiring is as follows: pin 1 = ground, pin 2 = hot, pin 3 = cold.
5
LINE IN/GUITAR [9/10] jacks and select switches
These stereo 1/4” phone jacks function as unbalanced guitar input jacks when the select switches are set to the
GUITAR position, and function as balanced line input
jacks when the switches are set to the LINE IN position. (The wiring is as follows: sleeve = ground, tip = hot, ring = cold.) Use the Gain knobs to adjust the input gain level.
6 Gain knobs and indicators [1-10] Adjust the gain
level for Inputs 1-10 individually. The adjustable range is from –2dBu to –58dBu for Mic Inputs 1-8, and from +4dBu to +42dBu for Line Inputs 9-10. The Gain indi-
cators will light green when a signal at a certain level
(–30dBFS) or higher is present. However, if the signal level exceeds –2dBFS, the indicators will light red.
7 MONITOR knob Adjusts the level of signals output
from the MONITOR OUTPUTS [L/R] jacks on the rear panel.
8 MIX knob Controls the balance of the signal sources
being output from the MONITOR OUTPUTS [L/R] jacks and the PHONES jack. With this knob turned to the far left, the US-1641 will output the signal input from the MIC
IN [1-8] jacks and LINE IN [9-14] jacks. With this knob
turned to the far right, the US-1641 will output the signal received from the computer via USB.
9 PHONES jack and PHONES LEVEL knob This
stereo 1/4" headphone jack outputs the same signal that is output from the MONITOR OUTPUTS [L/R] jacks. The
PHONES LEVEL knob controls the output level of the PHONES jack.

0 USB connector Use a USB cable to connect this to
the host computer. (Please note that this connector supports only USB 2.0 connection.)
A DIGITAL IN jack This is an RCA connector that
inputs a stereo S/PDIF digital signal.
B DIGITAL OUT jack This is an RCA connector that
outputs a stereo digital signal. Signals output from the
LINE OUT [1/2] or [3/4] jacks can be output digitally from
this jack (as set in the Control Panel). You can also select S/PDIF or AES/EBU as the digital signal format in the Control Panel.
C MIDI OUT connector Transmits MIDI messages
received from the computer.
D MIDI IN connector Receives MIDI messages.
The received MIDI messages will be transmitted to the computer.
E INPUTS [11-14] jacks and LEVEL switches These
are TRS 1/4" phone, balanced line input jacks. Use the
LEVEL switches to set the nominal level to –10dBV or
+4dBu.
You cannot adjust the gain level for these inputs.
F LINE OUT [1-4] jacks These are stereo TRS 1/4"
phone, balanced line output jacks (sleeve = ground, tip = hot, ring = cold). The nominal output level is +4dBu. These jacks output signals received from the computer. Use DAW software to switch between LINE OUT [1/2] and LINE
OUT [3/4].
G MONITOR OUTPUTS [L/R] jacks These are stereo
TRS 1/4" phone, balanced output jacks (sleeve = ground, tip = hot, ring = cold). These jacks enable you to monitor monaural mix input (1-14) signals and/or output signals received from the computer. Use the MONITOR knob on the front panel to adjust the output level.
H AC IN connector Connect the supplied power cable
to this connector and an AC outlet.
