Usb Indicator - Steinberg CI1 Operation Manual

The Controls and Connectors
INPUT 1/2 GAIN controls/PEAK
Indicator
Adjusts the input signal level. The signal that
has passed through the GAIN control will be
sent to the computer. To achieve the best bal-
ance of the recording level between S/N ratio
and dynamic range, adjust the level so that the
PEAK Indicator lights only occasionally and
briefly on the highest input transients.
[PHANTOM INPUT 1&2] button/
Indicator
This button switches the phantom power
(+48V) on ( )/off ( ). If you turn the button
on, the CI1 supplies phantom power to the ana-
log input jack 1 and 2 (XLR-type). The indicator
lights when the button is turned on. Turn this
button on when using a phantom-powered con-
denser microphone.
CAUTION
• Make sure that phantom power is turned OFF un-
less it is needed.
• When turning phantom power ON, make sure that
no equipment other than phantom-powered de-
vices such as condenser microphones are con-
nected. Devices other than condenser
microphones may be damaged if connected to the
phantom power supply. Note, however, that the
switch may be left on when connecting to balanced
dynamic microphones. When connecting an unbal-
anced device to the analog input jacks (1/4" phone
type) and phantom power is turned on, hum or
noise may result; this is not a malfunction or fail-
ure in the device.
• Do not connect or disconnect a device while phan-
tom power is applied. Doing so can damage the
connected device and/or the unit itself.
• To protect your speaker system, leave the monitor
speakers (powered speakers) turned off when
switching the phantom power on/off. It's also a
good idea turn all master control and output vol-
ume controls down to minimum. Neglect of these
precautions may result in large noise bursts that
may damage your equipment, your ears, or both.

CI1 Operation Manual
MASTER control
Adjusts the signal level sent to the LINE OUT
jacks. This allows you to adjust the overall vol-
ume without changing the relative volume bal-
ance among the channels. This control does not
affect the signal sent to the computer.
PHONES control
Adjusts the signal level sent to the PHONES
jack, since this output signal is not affected by
the MASTER control.
MIX control (INPUT—DAW)
Adjusts the signal level balance between the
signal from the analog input jacks and the sig-
nal from an application software, such as DAW.
This control does not affect the signal sent to
the computer.

USB Indicator

This indicator shows the communication state of
CI1 and computer. The indicator lights when the
CI1 is connected to the computer via a USB ca-
ble and communication with the computer is en-
abled.
