Reasons For Dynamic Losses In The Effects Loop; Compensated Out; Speaker Connections - Diezel Einstein Owner's Manual

process the signal, convert it back to analog, then send it to the amp. This is called ADA (analog
digital analog) conversion. It is necessary for digital effects units digitize your guitar signal so
that the processor can read and understand signal. Your tubes, however, need an analog signal to
operate, so the processor converts the signal back to analog before it goes back to the amp.
Generally, even in highest quality effects processors, this causes a change in the original signal,
typically a loss of tonality and warmth, also noticeable as a "harder" sound. When you use the
serial loop for an effects unit like this, then your signal will have been ADA converted at least
once. Tone junkies and vintage freaks alike will more than likely have hives developing by now.
But - as always, there is a better way. Use the Parallel loop and the Volume control in the rear
determines how much effect signal is being added to the original signal, which now still flows
through the amplifier. There is always an analog connection between the send and return jacks; a
parallel loop!
Important: You must set the mix control on the effects unit to 100% wet when using the
parallel loop. Otherwise there will be nasty phasing problems resulting in unsatisfactory tone.
The signal portion that is unaffected by the mix control in the effects unit would reach the
amplifier at a different time due to the cabling, and cause phasing cancellations.
3.2.3 Top 5 Reasons for dynamic losses in the effects loop
Many different factors can be responsible for loss of dynamics, aside from those mentioned in
3.2.2 (ADA conversion). A vital point that often leads to frustration is a maladjusted output level
of an effects unit. If the output level is too high, then it will cause unwanted distortion in the
power amp. If it is too low, then the rig will not sound punchy and might get lost in the band
sound. When used in the serial loop, the output of the effects unit determines the ultimate drive
signal strength of the power amp. The output level should be matched to give the best possible
sound with all channels without over driving the power amp section. (Unless this is desired for
power amp distortion) Headroom adjustments of 10% are usually sufficient.

3.2.4 Compensated Out

A frequency corrected signal will leave this jack if you connect it to a mixer or recording
device. Use it to quietly compose or send an auxiliary signal to a console etc. For quiet sessions,
just turn the master volumes to "0". Recording a loudspeaker through a microphone is the
preferred choice of recording engineers. The compensated out was designed as an alternative for
those that don't have a studio at your fingertips.

3.2.5 Speaker Connections

Einstein has 5 speaker jacks. 1 for a 16 Ohm load, 2 for 2 16 Ohm loads or 1 8 Ohm load, and
2 for 2 8 Ohm loads or 1 4 Ohm load. Confusing? Oh yes! Just do what it says on the jacks, and
you'll be fine.
