Page 5 EHRLUND ACOUSTIC PICKUP THE EHRLUND ACOUSTIC PICKUP (EAP) is an ultra-linear con- tact microphone for instruments with an acoustic sound box, such as the guitar, violin, double bass and ethnic instruments. It is made entirely in Sweden and is based on the same knowledge of sound recording as Ehrlund’s other products.
Page 6: Attaching The Pickup
ATTACHING THE PICKUP The EAP can be moved easily between different instruments. The pickup is easy to attach using adhesive on the sound box. The pickup can also be attached to the inside of the instrument via the sound hole. Each instrument is unique, which is why the positioning of the pickup needs to be tested in advance.
Page 7 The adhesive needs to be shaped into small balls about 3-4 mm in dia- meter and attached to the corners of the pickup. Never attach adhesive to the middle of the pickup. Then stick the pickup down carefully on the instrument so that there is about 2 mm of space between the pickup and the instrument.

Page 9 EHRLUND PREAMPLIFIER THE EHRLUND PREAMP has extremely low self-noise and low power consumption. It is optimised for use with the Ehrlund EAP pickup. It is able to operate with most existing accessories, such as foot pedals, effects pedals and transformer-equipped DI boxes.
Page 10: Features Preamp
FEATURES PREAMP Input 6,3 mm tele jack 6,3 mm tele jack. The Preamp turns itself off when the Output output cable is disconnected. Phase switch The unit has a phase switch (0-180°) which is used to avoid feedback during live performance. The unit can be adjusted for high/low input from the High/Low microphone.
Page 11: Operation High/Low
OPERATION HIGH/LOW The High/Low switch is used when you find a point on the instrument where you get a good, strong signal. The place where the sound is loudest is not normally the point on the instrument where you get the best sound.

Page 14: Things To Bear In Mind
THINGS TO BEAR IN MIND • Cable microphonics are one of the drawbacks of the pickup system, regardless of brand. These microphonics are a mechanical property of the cable. If you set the cable in motion, for example by hitting it or through other strong movement, you induce mechanical waves, which propagate through the cable to the pickup.
Page 15 The Ehrlund Preamp does not have any filters; it is a pure low-noise amplifier. • The preamp can also be used for electric guitars. In this case connect it directly to the mixing board.
Page 16 A triangular membrane is the secret behind the clean sound of an Ehrlund Microphone. The technology is based on knowledge of the properties of sound that dates back thousands of years. Just as a circular shape gives sound resonance, a triangle muffles resonances fast.
