Analog Elemental Series
Optional Features
• Optional for all processing modules: Lundhal transformers at the input and output stages.
Premium preamplifier modules integrate input and output transformers. Preference
preamplifier modules cannot be fitted with transformers. Transformers are not visible
from the outside and are only available as a factory option during purchase. Retrofitting is
not contemplated. More information on transformers below.
• Optional for every Analog Elemental unit: additional digital output via a converter module.
For more information on the Converter Module refer to page 9.
• Additional functions for Channel Strip modules: channel strip switcher on the rear. When
engaged, this switch internally forwards the output signal of the first module directly into
the input of the second module, making external cabling unnecessary.
Information on Transformers
All processing modules can be equipped with input and output transformers. Exceptions:
Preference Mic Pre is not available with transformers, Premium Mic Pre always comes with
inout and output transformers.
We think a good part of the „warmth“ that is commonly associated with vintage gear comes
from transformers. With transformers the low end and lower mids sound rounder, full-bodied
with more punch. The top end gets a silky touch and benefits from improved presence without
sounding boosted. Reasons are reduced odd harmonics (which produce harsh top end
impressions) and a slower characteristic compared to electronic stages which causes a more
voluminous sound.
We recommend transformers especially for vocals while electronic stages can be better for
highest precision in signal transmission (transients), but in the end it‘s a question of personal
taste, applications or for example which mics are in use.
Transformers transmit the signal by induction. This means there is no static connection (like
a wire) to transmit the signal. This protects the unit from damage caused by power failures in
the input/output connections. In addition, hum problems are effectively avoided if balanced
connections are used throughout. That‘s why transformers can be very interesting for live
units or in units used for facilities that need highest operational safety (broadcast, sound
reinforcement). Another notable advantage for many live and recording applications is that
very long cable lengths are possible with no loss in signal quality. At the end of the day, it
depends on personal taste, main applications or for example on the microphone and other
equipment if transformers are required or not.
