Schatten Artist II Endpin Jack Preamp
Two Channel Preamp with Phantom Power Capability
 |
This two channel preamp is the same preamp that is supplied
with our HFN series of guitar pickups, RG-03A and NR-2A resonator pickups,
and TCA
tricone pickup.
So the choice is your's...do I stick a battery in there or don't I?
The preamp is
capable of running from virtually any power source. It can be run
from a 9 volt battery onboard the instrument or by any outboard power
source between 11 and 48 volts such as Phantom Power as provided by a
mixer, PA system, amp or outboard battery pack .....this multi power
capability is not just an option, it comes as a standard feature.
Control at your fingertips
The Artist II Endpin Jack Preamps are available with Thumbwheel volume controls. These discrete units attach simply and easily to the underside of the top at the edge of the soundhole with 3M VHB foam tape.

Features
| 2 Channels - allows the independant mixing of two pickups |
| Trim pots on the circuit board allow setting of maximum gain levels for each channel |
| Gain variable from 0 db to 24 db |
| Battery life extended to approx. 800 hours with a 9 volt battery |
| Multi power capability - Preamp may be run from 9 volts onboard or from any Phantom Power source outside the instrument (up to 48 volts dc). |
| Thumbwheel volume controls are available |
| CAB-1 cable allows you to run from outboard power sources |
| RP-1 remote power module (18volts) allows you to run from an outboard power source when mixer/PA/amp Phantom Power is not available. (requires CAB-1 cable) |
Having 2 separate channels on this preamp will allow you to mix and balance any of our piezo pickups with a mag pickup that you might already have.
Output of the Artist II preamp is mono.
This preamp also will match up well with virtually any other piezo crystal pickup from any manufacturer and as such is a good replacement preamp for other brands as well.

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.
