Front Panel - Steinberg UR 824 Operation Manual

Front Panel

MIC/LINE/HI-Z (XLR/phone type,
balanced/unbalanced)
For connection to a microphone, digital
instrument, electric guitar, or electric bass.
HI-Z switch
Turns on ( ) and off ( ) the HI-Z of the MIC/
LINE/HI-Z.
Turn this switch on when connecting high
impedance instruments, such as an electric
guitar or electric bass, directly to the MIC/LINE/
HI-Z.
When you turn this switch on, use an unbalanced
phone type cable for connection between the
instrument and the MIC/LINE/HI-Z. If you use a
balanced cable or an XLR cable, this device will
not work correctly.
CAUTION
• Do not connect or disconnect a device while turning
on the HI-Z switch. Doing so can damage the
connected device and/or the unit itself.
• To protect your speaker system, leave the monitor
speakers turned off when turning the HI-Z switch on/
off. It's also a good idea to turn all output volume
controls down to their minimum. Neglect of these
precautions may result in large noise bursts that may
damage your equipment, your ears, or both.
PAD switch
Turns on ( ) and off ( ) the PAD of the analog
input jacks (MIC/LINE/HI-Z and MIC/LINE
INPUT).
When you turn this switch on, the input signal
level of the analog input jacks will be attenuated
by 26 dB. Turn this switch on when connecting
high output equipment, such as a synthesizer, to
the analog input jacks.
Panel Controls and Terminals (Details)
SIG/PEAK lamp
Indicates the input signal level of the analog input
jacks (MIC/LINE/HI-Z and MIC/LINE INPUT).
Lamp status Description
Red -3 dB or more
Green 40 dB or more – less than -3 dB
Dark Less than -40 dB
INPUT GAIN knob
Adjusts the input signal level of the analog input
jacks (MIC/LINE/HI-Z and MIC/LINE INPUT). The
adjustable range varies depending on the on/off
setting of the PAD switch.
PAD Range
On -34 dB – +10 dB
Off -60 dB – -16 dB
+48V button
Turns on (lit) and off (dark) the phantom power of
XLR type connections on analog input jacks
(MIC/LINE/HI-Z and MIC/LINE INPUT).
When you turn on this button, phantom power will
be supplied to the two adjacent analog input
jacks. Turn on this button when connecting
phantom powered devices, such as a condenser
microphone, to the analog input jacks.
CAUTION
• Make sure that phantom power is turned OFF unless
it is needed.
• When turning phantom power ON, make sure that no
equipment other than phantom-powered devices
such as condenser microphones are connected.
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 unbalanced device to the MIC/LINE/HI-
Z and MIC/LINE INPUT and phantom power is turned
on, hum or noise may result; this is not a malfunction
or failure in the device.
