CHAPTER 1: Overview
CHAPTER 1: Overview
Introduction
Welcome to KYRA, DirectOut’s monitoring device for signal control in MADI
environments. KYRA provides three MADI inputs and outputs, an analog stereo
line out and an AES I/O. Up to four stereo or eight mono channels can be summed
with individual levels onto a main mix. The main mix is output by the integrated
speakers and the other outputs.
Feature Summary
MADI Ports 1 x SC multi-mode connectors
1 x SFP (empty cage without module)
1 x coaxial BNC connectors with PFT technology
(power fail through)
MADI Formats 56/64 channel, 48k/96k Frame
Sample Rates 44.1, 48, 88.2, 96 kHz +/-12.5%
AES Port 1 x AES3 I/O (DSUB-9)
Line Output 1 x stereo, balanced, +24 dBu (DSUB-9)
Speaker 2 x speakers
Headphone Output 6.3 mm TRS jack, stereo, +18 dBu
USB Port USB 2.0 port for firmware updates and remote con-
trol.
Power Supply This device is equipped with one wide range power
supply (84 V to 264 V AC / 47 Hz to 63 Hz / safety
class 1)
How it works
A channel pair or two single mono channels are selected via the source panel.
Each of the four source panels can be configured to either stereo or mono. The
mono channels for left and right are summed with individual levels (mix level) onto
the main mix (stereo). The volume (master volume) of the four outputs (speakers,
line out, phones, AES out) is adjusted (or muted) individually.The channel selection
can be locked against unwanted modification.

CHAPTER 3: Installation
Retain the protective cap if the optical port is unused. This will protect against soil-
ing which can lead to malfunction.
Avoid damage from condensation by waiting for the device to adapt to the environ-
mental temperature. Proper operation can only be guaranteed between tempera-
tures of 5ºC and 45ºC and a maximum relative humidity of 80%, non-condensing.
Ensure that the unit has sufficient air circulation for cooling.
CHAPTER 3: Installation
Installing the Device
1. Open the packaging and check that the contents have been delivered
complete and undamaged.
2. Fix the device in a 19’’ frame with four screws, or place it on a non-slip
horizontal surface.
WARNING!
3. Remove the protective cap from the optical MADI port(s) before use.
NOTE!
4. Connect signal cable(s) for the MADI signals.

page 15 of 36Kyra Manual - Version 1.2
CHAPTER 3: Installation
Do not connect voltage sources to the analog outputs. This may cause damage at
the output stages. Observe the technical specifications listed in this document.
5. Connect the signal cables for the analog and AES3 audio signals to the
DSUB-9 adaptor. Connect the adaptor to the DSUB-9 plug at the rear panel.
The adaptor converts from DSUB-9 (male) to:
• 2 x XLR male (Line Out L/R)
• 1 x XLR male (AES3 output)
• 1 x XLR female (AES3 input).
WARNING!
6. Optional: Connect an USB cable to the USB port for remote control or
firmware updates. This requires the USB Serial driver (Windows) being
installed first. The driver and the installation instructions are available at
www.directout.eu.

CHAPTER 4: Operation
Introduction
This chapter describes the basic operation of the device.
Note that throughout this manual, the abbreviation FS refers to sample rate or
sample frequency. So, when dealing with scaling factors, the following sample
rates can be written as:
• 44.1 kHz or 48 kHz = 1 FS
• 88.2 kHz or 96 kHz = 2 FS
• 176.4 kHz or 192 kHz = 4 FS
CHAPTER 4: Operation
Global Control
The power switch is on the back panel:
Power 1 Switch
Enable / disable power supply.
Power C13 socket
Connect the power supply here (84- 264 V AC).
NOTE!
Unlit leds at the front panel do not guarantee that the device is free of voltage. To
ensure that the device is completely disconnected from mains voltage, the power
chords must be disconnected.

page 19 of 36Kyra Manual - Version 1.2
CHAPTER 4: Operation
Input Selection
One of the three MADI inputs is used a input source.
Selection priority of locked inputs: BNC > SC > SFP
The selection state is indicated by two LEDs. The AES input is available as separate
source in each source panel.
Selected MADI Input LED BNC (green) LED SC (green)
BNC ON OFF
SC OFF ON
SFP ON ON
no signal lock OFF OFF
The MADI input is used as sync source for the device. The AES input is used as
clock source only if no MADI input signal is present.
The channel mode (56ch <> 64ch) is detected automatically.
All MADI outputs carry the signal of the selected MADI input.
The device will switch to 2 FS operation automatically when a 96kFrame signal
has been detected.

page 20 of 36 Kyra Manual - Version 1.2
CHAPTER 4: Operation
Channel Selection
The upper part of the four source panels each provides access to the individual
channels of the MADI signal or the AES input.
Each source panel can be set individually to stereo or mono mode:
Stereo: a channel pair is used- e.g. channel <03> & <04>.
The mix level setting is applied to both channels.
Mono: individual channels for left and right are selectable- e.g.
channel <03> & <26>. The mix level setting is applied to
each channel individually.
In mono mode the right channel can be set to ‘link’ (<_L>) to copy
channel selection and mix level from left to right channel e.g. <03> & <_L>.
All four source panels are operated identically.
