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 monitoringenvironments.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 RadisavljevicDanny McKinney

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.
