1 - Safety instructions and important notes

Pleasereadandobservethewarningsandinstructionsinthisowner'smanualtoinsureyourpersonal

safety and proper care of your unit.

The Odéon-m1 digital-to-analog converter has been designed with safety in mind.

Improper use may however result in electric shock or fire hazard. Please read the following safety

instructions carefully.

1 Do not remove the unit’s cover as you will be exposed to dangerous voltages which may result in

electric shock. Refer servicing to qualified technicians only.

2 When connecting components to your Odéon DAC, it is a good idea to turn it off or to make

sure that it is not connected to the main electrical outlet.

3 To reduce the risk of fire or electric shock, do not expose the Odéon DAC to rain or heavy

moisture. Wait at least one-half hour before plugging the amplifier in after transferring it from a

cold place to a warmer room allowing for internal condensation of water to dissipate.

4 The Odéon DAC has openings provided for ventilation. Proper operation may only occur if

theseopeningsarenot obstructedorcovered. Donotcovertheunit.Itshouldnotbe usedinabuilt-

in installation such as a bookshelf or rack unless proper vertical ventilation is provided.

5 Itstronglyrecommendedtolowerthevolumeknobto theminimumbeforeturningyourOdéon

DAC on if the attenuated output is being used. Failing to do so could send high audio levels to your

amplifier and could overload and damage your amplifier or speakers.

2 - How to properly care for your DAC

Heat

Keep the Odéon DAC away from heat sources such as radiators, space heaters, stoves or other

sources.

Water and moisture

Do not use the Odéon DAC near water sources such as bath tubs, sinks, wash bowls, swimming

pool or other sources that may lead you to get water in the unit. Do not spill liquid of any kind on

the unit.

Objects entry

Do not insert objects of any kind through the unit's opening vents as they may touch electric parts

with dangerous voltages or may short-out parts inside and damage your DAC.

Stack and height

DonotstacktoomanycomponentsorheavyobjectsontopoftheOdéon. Doingthiscouldprevent

heat from dissipating properly out of the top vents and could cause damage or deformation to the

unit's case.

Cleaning

Use a simple damp soft cloth to clean. Do not use liquid or abrasive cleaners.

Make sure your Odéon is not connected to the electrical outlet before cleaning it.

Protection

For added protection, you may choose to disconnect your Odéon from the wall outlet if you are

planning to leave it unattended for a long period of time or during storms. This may prevent

damage due to lightning.

Volume

Reduce the volume on your preamplifier or Odéon to the minimum level before you turn on the

unit. Doing so will prevent sudden loud volume sounds which could cause speaker, amplifier or

hearing damage.

4 - Understanding the Odéon-m1

TheOdéon-m1ismainlya24bitDigital-to-AnalogConverter(DAC)andalsoacommoditypassive

preamplifier which allows you to not only connect digital but also analog sources.

A DAC is a unit that converts digital data from CDs or any other digital medias into analog music

that can be fed to a power amplifier for listening. Digital data is usually extracted from Compact

Disks(CD)usingatransport oraplayerandcanbe fedtotheOdéonthrougheither a digitalcoaxial

interconnect cable (commonly called S/PDIF) or a fiber optic. CDs store music using a digital

format of 16bits/44.1kHz but there are other formats which allow to increase the fidelity of digital

conversions such as the recent availability of 24bits/96kHz on audio DVDs (Digital Versatile Disk)

sometimesalsocalledDAD(DigitalAudioDisk).TheSuperAudioDiskformat-recentlyintroduced

by Sony/Philips - does not offer a way to carry digital data out of the box and are not compatible

with widely used S/PDIF or AES/EBU consumer and professional formats.

TheOdéon-m1willconvertanydigitaldatafrom12to24bitsatsamplingratesof32kHz,44.1kHz,

48kHz,88.2kHzand 96kHz. Youcanconnect3and up to 4differentdigitalsources to your Odéon

and use the buttons on the front panel to instruct it which source to convert.

TheOdéon-m1is also apassivepreamplifierthat allowsyou toconnect3andup to4existinglegacy

analog sources. Passive means that there are no active components in its analog section. You can

selectwhichanalogsourcetoroutetotheOdéonoutputandthesoundispassedonas-isunmodified

so you get out exactly what you feed in.

Your OdéonDACistheresultof the latest developments in both Digital and Analog domains along

with the highest quality components providing you with the most natural sounding conversion you

can get from your digital sources.

The DAC is a 24 bits delta-sigma converter which is composed of a 5th order digital interpolation

filter, a digital filter, a switched capacitor filter and a final 2nd order filter all developed together to

provide an overall constant group delay insuring no phase shift and a perfect stereo imaging. The

volume attenuator is a high-quality ALPS stereo potentiometer and the passive analog matrix is

made of the highest quality miniature air sealed relays with gold-plated over silver contacts.

The way music should sound Odéon-m1

There are three simple digital inputs on the back which can be used to connect digital sources

such as a CD, DVD player/transport or any other digital source. The Odéon DAC will receive

and decode digital audio data according to the AES/EBU IEC-958 also known as S/PDIF or

toslink as well as EIAJCP340/1201 professional(1) or consumer formats. The digital inputs are

activated using the front panels buttons In.1 through In.3 (see controls on page 6).

Whenconnectingthe AC3/PCM outputfromaDVDplayer to aOdéondigitalinput,make sureto

switch the DVD player format to PCM. RF outputs from laser disk players can not be connected

directly to the Odéon DAC without the use of a RF to S/PDIF converter.

Either optical OR the coaxial inputs can be used when connecting a source to the Odéon DAC for

each of the digital inputs. The Odéon will automatically select the format used but you should

NEVER connect both the coaxial and optical sources for any one input.

There was a time when optical receivers were not as performant as today. Recent technologies offer

excellent constant time delay optical transmitter/receivers. For this reason if the digital source offers

both optical and coaxial outputs, it is recommended to use the optical connection rather that the

coaxial as it ensures separation of the units grounds and offers signal immunity to EMI.

(1) Professional sources may require an impedance adapter from AES/EBU to 75 ohm S/PDIF. Such adapters

are commonly available from many sources.

5 - Connecting the Odéon-m1

5.1 - The Digital Inputs

The way music should sound

Odéon-m1

5.2 - The Analog Inputs

The Odéon offers 3 analog inputs which can be used to connect legacy analog sources such as a

tuner, RIAA preamplifier or any other analog sources with a high-level line output, turning the unit

into a commodity passive preamplifier. These sources can be selected using the front panel buttons

labeled An.1 to An.3 (see controls on page 6).

A passive preamplifier is a unit that does not insert any active components in the analog signal’s

path. As a preamplifier, the Odéon becomes a perfect transparent switch that lets you enjoy your

legacy analog components just the way they sound with no added distotion.

As a passive preamplifier, the Odéon only inserts one high-quality air sealed gold-plated over silver

contact switch to connect the selected analog source to the output exactly as-is. If using the variable

output, an additional high-quality potentiometer (ALPS) is added.

An exception however is made for the monitor analog output which includes a highly transparent

unity gain buffer to avoid interference between the unknown load of the monitor and the analog

signalbeinglistenedto.Themonitor buffer howeverhas nogainandbenefitsfrom BirdlandAudio’s

fifteen years of research on building transparent electronics. But don’t take our word for it, go ahead

and try it!
