Chapter Three: Peripheral Connections

3.1 Front Panel Connections

3.1.1 The input jack ("IN") receives your Electric Guitar signal by means of a shielded guitar cord
with 1/4" mono style plug. Your guitar cord is an important part of your signal chain and its
quality and construction type clearly affect the overall tone of your rig. Try and buy the best
quality guitar cord that you can or want to afford. Call us if you have doubts and need
recommendations. This is where the smart "weak link" comment comes in.
3.1.2 Cable ABC
Some cords and cables sound very neutral; others color the sound spectrum and/or
attenuate high frequencies due to capacitance inside the wire and the shield. What are we talking
about? OK. A capacitor is used in electronic crossovers, amongst other things, to divide low and
high frequencies. Capacitance in a cable cuts your guitar's high end to a certain degree.
Generally, the longer of a cord you use, the more of the cord's inherent characteristics will be
audible.

3.1.3 Cable Selection

In certain circumstances, it is desirable to match a guitar cord to a specific instrument. One
may use the otherwise undesirable qualities of a cord to one's advantage, if one has the time and
patience to experiment with different cords and guitars. This should be done while playing with
your band, or while recording. Sometimes it is difficult to tell a component's true advantages
until it is used in the right context.
A guitar that has very piercing highs could theoretically be tamed down somewhat by using a
long guitar cord that offers some high-end attenuation. The loops of your Einstein send signals at
higher levels and impedances, which makes this section of wiring less sensitive. You should still
use reliable and good quality wiring for all loops.

3.2 Rear Panel Connections

3.2.1 Send/Return Loop

The system consists of 2 separate Loops. It allows creation of effects path in either serial or
parallel configurations. The individual channel volume controls determine the signal strength at
the send jacks. The range is ... to +10dB. The output impedance is 4.7 kΩ. To use the Send/
Return Loops, connect the "Send" to the "return" or "input" or "in" of the effects unit. Be sure to
adjust the input level of the effects unit to the amplifiers level. Most effects units have led bar or
other level control devices. The Output of the effects unit must be connected to one of the return
jacks, parallel,, or serial. If you use the parallel return, then the signal can be mixed to the
original signal via the rear panel mounted "Volume" control.
3.2.2 Parallel or Serial
Which is better for you? Read on.
There are 2 ways to handle effects signals. The serial loop interrupts the signal path of the
Einstein and the signal is sent to the processor, becomes processed, then sent back to the serial
return into the power amp. Digital effects units often digitize this signal once received, then
