Manual
This Operation Manual explains how to use the 
device. The explanations in this manual assume that 
you’ve set up the device and prepared it for use 
according to the included Getting Started 
document. If you haven’t done that yet, refer to the 
Getting Started document and complete the setup 
before reading this manual.
Features
High-resolution Microphone 
Preamplifiers (D-Pre) 
Discrete microphone preamps featuring a high-
performance inverted Darlington circuit 
configuration achieve low distortion and noise while 
delivering sound with eminently musical balance 
and character.
Supports a Variety of Inputs
Switchable phantom po wer is provided for 
condenser microphones, electric guitars and 
basses can be directly connected via a HI-Z (high 
impedance) input, and a PA D is provided for input 
matching with high-level signals from electronic 
instruments. Optical input connectors enable direct 
digital input in ADAT or S/PDIF format from a variety 
of digital audio devices, while a BNC-connector for 
word clock input and ou tput allows precise 
synchronization with other digital equipment.
Powerful DSP Mixer (dspMixFx)
A DSP mixer that can mix up to 24 input channels to 
four stereo outputs is built in. Two of those stereo 
mixes can be independentl y assigned to separate 
headphone outputs. It is also possible to directly 
route a stereo input to any specified stereo output. A 
number of DSP effects that can be applied to input 
signals are also provided, and since it is a hardware 
mix with there is no monitoring latency.
DSP Effect “Sweet Spot Morphing 
Channel Strip”
The Sweet Spot Morphing Channel Strip (“Channel 
Strip” for short) is a multi-effect that combines 
compression and EQ. Advanced sound engineering 
know-how is condensed into a number of presets 
that can simply be recalled as required for 
professional results. Eight channel strips are 
provided, and each can be assigned to the monitor 
sound only, or to both the monitor and recorded 
sound.
DSP Effect: REV-X Reverb
REV-X is a digital reverb platform developed by 
Yamaha for pro audio applications. One REV-X 
effect is included in this unit. Input signals can be 
sent to the REV-X effect, and the REV-X effect is 
applied only to the monitor outputs. 
DSP Effect VST Plug-ins Included
VST Plug-in (VST3.0, page 26) versions of the 
Channel Strip and REV-X effects are included for 
use with Cubase series or similar VST-compatible 
DAW software.
Cubase AI Included
Steinberg Cubase AI digital audio workstation 
(DAW, page 26) software is  included. Cubase AI is 
the entry-level version of  the Cubase series DAW 
products, providing the basic functionality you need 
for music production and editing.

UR824  Operation Manual4
Panel Controls and 
Terminals (Details)
Rear Panel
DC IN 16V
For connection to the AC power adaptor.
 Grounding screw
For connection to a ground wire.
If you have a problem with hum or noise, use this 
terminal to connect to ground. The noise may be 
reduced.
 USB2.0 (USB port)
For connection to a computer.
 WCLK switch
Switches between IN and OUT for the upper 
WCLK terminal.
 WCLK IN (OUT)/OUT (BNC connector)
For connection to the device which transmits and 
receives the word clock.
 OPTICAL A/B IN/OUT (optical)
For connection to a digital audio device.
You can select the format of the OPTICAL A/B 
between ADAT and S/PDIF. To select the format, 
use the “Setup Window” (page 12) in the section 
“dspMixFx UR824” or the “Settings Window” 
(page 18) in the section “Dedicated Windows for 
Cubase Series.”
You can select the output signal of the OPTICAL 
A/B OUT. To select the output signal, use the 
“Setup Window” (page 12) in the section 
“dspMixFx UR824” or the “Output Routing 
Window” (page 17) in the section “Dedicated 
Windows for Cubase Series.” 
LINE OUTPUT 1–8 (phone type, 
balanced/unbalanced)
For connection to monitor speakers. When the 
monitor speakers have a balanced input, connect 
them with a balanced cable.
You can select the output signal of LINE OUTPUT 
1–8. To select the output signal, use the “Setup 
Window” (page 12) in the section “dspMixFx 
UR824” or the “Output Routing Window” (page 
17) in the section “Dedicated Windows for 
Cubase Series.”
 MIC/LINE INPUT 3–8 (XLR/phone type, 
balanced/unbalanced)
For connection to a microphone or digital 
instrument. 
						

							Panel Controls and Terminals (Details)
UR824  Operation Manual5
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 (0 ) 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.
 PA D  s w i t c h
Turns on (0 ) 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 inpu t 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. 
SIG/PEAK lamp
Indicates the input signal level of the analog input 
jacks (MIC/LINE/HI-Z and MIC/LINE INPUT).
 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.
 +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 po wer 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 micr ophones 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.
