New Schatten AD-02 Autoharp Pickup

 

 A Better Way Of Amplifying Your Autoharp

                     AD-02

       The new AD-02 is a powerful, low profile pickup that was specifically designed for the autoharp. The new low profile sensor fits under the strings on most autoharps and attaches quickly and easily to the instrument using the double sided tape supplied with each pickup.

     The output jack can be mounted in a number of locations on the instrument depending upon the player's preference.

     This pickup has been designed to operate properly and sound terrific without the use of a preamp when plugged into any 'normal' amp (guitar amp, bass amp, etc.). As with any pickup, the sound can be further enhanced with an outboard preamp. If you require the added ability to be able to plug directly into a P.A. or mixer then you may wish to add our  Mini Pre belt clipable preamp.

Details


AD
-02

     The AD-02 is a low profile pickup and is only 3/16" (4.75mm) thick. On most autoharps the pickup sensor can be mounted on the soundboard of the instrument right under the strings as there is normally enough clearance. It may be mounted on the underside of the top or on the inside back or outside back of the instrument depending upon access and preference.

     The pickup comes complete and ready to use.  It is prewired to a 1/4" output jack that is easily mounted to the edge of the soundboard with two tiny screws

This  passive  pickup is designed to work  properly and to sound good when plugged into a 'normal' electic guitar amp. For more information  on amplification click on the 'About Pickups, Preamps, Amps' tab.

Pictures

 

The above photo shows the simplest and easiest placement for both the pickup sensor and the jack assembly. There is no need to take the strings off to do this installation.


   

 

An alternate placement. This does require the removal and reinstallation of a couple of strings.


The sensor may be completely hidden by mounting it beneath the chord bar area.


 

About Pickups and Amplification

 

Terminology

Passive Pickup - A piezo pickup.

Impedance - To simplify things as much as posssible we'll say that impedance refers to the range in which an amplifying device can 'hear' a pickup plugged into it.

Preamp - A device specifically designed for use with piezo pickups that increases the signal strength and lowers the impedance of a passive pickup.

Active Pickup - A piezo pickup with an attached preamp.

Microphone Preamp - a device that may be built into P.A.systems and mixers that is designed to work with microphones. These units will not generally work with passive pickups.

'Normal' Electric Guitar Amps: A passive pickup has an impedance of approximately 2 mega ohms (2 million ohms) which virtually all 'normal' electric guitar amps can generally handle without issue.

 'Acoustic' Amps: may or may not require the use of a preamp with a pickup and that will depend upon whether or not there is a special built in preamp section to that amp that specifically allows for the choice in plugging in either a passive (non-preamped) or active (preamped) pickup. This choice is quite often in the form of pushbutton on the amp's control panel. Many acoustic amps show a selection that may indicate the choice of 'high impedance' and 'low impedance'.

Low impedance in these instances usually indicates that in this range the amp will handle an impedance of 1000 ohms or less - which will allow active pickups with preamps to be used.

High impedance in these instances may indicate an allowable impedance into the 2 or 3 mega ohm range - which will allow passive pickups to be used. Or it may indicate a maximum input impedance allowed of  20,000 ohms or less - which will handle magnetic electric guitar pickups but not passive pickups. You should carefully read the technical specifications of your acoustic amp in order to see what it will do.

P.A. Systems, Mixers: all of these units will require the use of a preamp between themselves and a passive pickup. Microphone preamps built into P.A.'s and mixers are not designed for use with passive pickups and will not work properly.

Computers: Due to the vagaries and variables inherent in the sound cards found in computers, the only thing that we can advise is that a preamp will almost certainly be necessary.
