INTRODUCTION
Your SR1a Earfield Monitor is the result of nearly a decade of reimagining and
reinventing the headphone, as we have always known it.
Designed to be a full-range Mix and Mastering monitor that could eliminate the
acoustical anomalies and variables, experienced in typical far-field and near-
field monitoring
environments.
For this task, it was realized that no existing driver could perform this
function without typical headphone solutions of sealed chambers and acoustic
resistance, defeating the concept of a full range EARFIELD MONITOR entirely.
With it’s totally open design and highly advanced ribbon technology, the SR1a
Earfield Monitor represents an entirely new generation of listening and studio
monitoring.
All parameters considered, we believe the SR1a to be the truest reproduction
of musical and artistic intention, available at this time.
We sincerely appreciate your trust in our work, as evidenced by your purchase,
and hope you will benefit from a lifetime of beautiful music and joyful
ownership.
Happy Listening,
Alex Radisavljevic

(1) Amp/Ribbon Interface

(2) Red Banana Cables – Interface to Amplifier (L+/R+)
(2) Black Banana Cables – Interface to Amplifier (L-/R-)

Amplifier Requirements
Your SR1a Earfield Monitor requires an outboard amplifier with a minimum of
100-watts RMS. Amplifiers of 200-500 watts RMS is also suitable and even
preferred but, care must be given to not overdrive the ribbon.
When overdriving the ribbon, you’ll notice a slapping sound, caused by the
ribbon reaching its excursion limits. For this to occur, the volume level will
be very high with bass-heavy content.
In general – Better the amp, Better the sound.
Audio Connections
Rear View of
Amp/Ribbon Interface
The rear panel binding posts of the Amp/Ribbon Interface connect to the speaker outputs of your amplifier, using (4) banana cables (provided).
Front View of Amp /Ribbon Interface
The front panel, 4-pin MALE/XLR, is for connection to the SR1a, using the (1)
FM/XLR to TRRS/TRRS cable (provided).
XLR is “gender-reversed” to prevent conventional headphone amps from being
used, with the SR1a, due to the 0.2-ohm load presented to the amplifier by the
ribbons.
SR1a Vertical Positioning
The ear canal
should be at the vertical center of the left and right ribbons.
Adjustments can be made via the leather headband.
For Camber and Lateral Force adjustments, please refer to our video “SR1a
Fitting Adjustments”. This can be found on our website, under ”support” and on
YouTube.
SR1a Horizontal Positioning
For initial horizontal positioning, we suggest starting with the inner grill
to be about 1/4” from the edge of your outer ear. This position is good for
most recordings.
You are encouraged to experiment with wider horizontal positioning, especially
with orchestral and acoustic music.
