USB connections

Using the included USB cable, connect the US-1800 to your computer as shown in the illustration.

NOTE

Some USB devices access the USB bus frequently. In order to avoid dropouts, clipping noise and other problems with the audio signal, we strongly recommend that you do not connect any other USB devices, with the exception of a mouse and keyboard, to the same computer as this unit.

Audio connections

Connect the output signal of your mic, guitar, keyboard, or other audio device to the US-1800, where it will be converted into digital audio and sent via USB to your computer. Connect the output of the US-1800 to your speakers (via an amp) or headphones, so you will be able to monitor the audio signals coming into the US-1800 or being produced by your computer.

Use the MIX knob to adjust the balance between the computer output signal and the input signals from microphones, guitars and other connected equipment.

Mic

Connect your mics to the MIC IN (1-8)jacks (XLR) on the front panel. If you are using a condenser mic that requires phantom power, turn on the PHANTOM (+48V) switch.

You can use more than eight microphones by connecting them via an external mic pre-amp. In this case, connect the output of the mic pre-amp to the INPUTS (11-14) jacks on the rear panel.

 

CAUTION

 

••

When the PHANTOM (+48) switch is ON, making an

 

unbalanced connection with a dynamic microphone

 

could cause the device to break.

••

Do not connect or disconnect any microphones when

 

the PHANTOM (+48) switch is ON. Doing so could cause a

 

loud noise or break the device.

••

Minimize the levels of the PHONES and MONITOR knobs

 

on the front panel before turning the PHANTOM (+48)

 

switch ON or OFF. Depending on the microphone, failure

 

to do so could result in a loud noise that might harm other

 

devices and damage human hearing.

Guitar

When connecting a guitar or bass guitar directly to this unit, use a GUITAR/LINE IN (9-10)standard jack on the front panel and set the GUITAR/LINE IN switch to GUITAR.

Analog connections with keyboards, drum machines, sound modules and cassette, MiniDisc and CD players, etc.

Connect the analog signal outputs of these types of devices to the GUITAR/LINE IN jacks (9-10) on the front panel or to the INPUTS jacks (11-14) on the rear panel.

When connecting them to the GUITAR/LINE IN jacks (9-10), set the GUITAR/LINE IN switch to LINE IN.

 

NOTE

 

••

When a device is connected to a GUITAR/LINE IN jack

 

(9-10), you can use this unit’s gain control to adjust it in a

 

continuous range from –6 dBV to –52 dBV.

••

When a device is connected to an INPUTS jack (11-14), you

 

can set the nominal level to either –10 dBV (−10) or +4

 

dBu (+4).

Digital connections with sound modules and MiniDisc and CD players, etc.

Connect the digital inputs and outputs of these types of devices to the DIGITAL IN and OUT jacks on the rear panel of this unit.

 

NOTE

 

••

This unit’s digital input is an RCA pin jack that accepts S/

 

PDIF signals.

••

This unit’s digital outputs can output to either S/PDIF or

 

AES/EBU signals. Use the control panel to set the output

 

type.

Monitor speakers

Connect speakers for monitoring (powered speakers or an amplifier and speakers) to the MONITOR OUTPUTS jacks on the rear panel.

Headphones

Connect headphones to the standard stereo PHONES jack on the front panel.

MIDI connections

Connect sound modules, keyboards, synthesizers, drum machines and other MIDI devices to this unit as shown in the illustration. MIDI signals input through the MIDI IN connector on the rear panel of this unit are sent as is to the computer. The MIDI signals sent from the computer to this unit are output through the MIDI OUT connector on the rear panel. As a result, by sending and receiving MIDI time code (MTC), you can synchronize computer recording software that is MTC-compatible with MIDI devices.
