LEA
Level Engine Automation (LEA)
The LEA Engine is a unique technology for levelling your interviews while recor-
ding. In comparison to standart AGC`s and Limiters the LEA engine knows to
excel by not creating artefacts or common pumping noises. Even with blanking
levels or loud ambient noise the LEA Engine works perfectly and levels smooth-
ly, just like an engineer inside your mic. The Engine also uses limiters to avoid
sudden lash outs and levels smoothly within (common volumes levels). It also
perfectly avoids raising noise floors during mute seconds of an interview.
The user himself doesn‘t need to bother with setups. All he has to do is start a
recording. The LEA Engine provides the freedom to solemnly concentrate on
the interview while guaranteeing to process your recording in the highest pos-
sible quality. *

PUC² advanced operation (Zero Latency Monitoring)
PUC² has a special feature which allows the user to monitor it‘s input signal
directly at all of it‘s outputs simultaneously. This bypasses the USB conversion
and computer, offering very low unput to output times, typically less than 5ms,
even at low sample rates. This can be turned on by closing the tip sand sleeve
(ground) contacts on the 3.5mm sterei ZLM siwtch jack on the unit. The USV
sound output of the computer ist mioxed into the input signal, and by default,
both sign als are dimmed (reduced in level) by 6dB to avoid overloading the
output stages. This automiatic level adjustment can be over-ridden by connec-
ting the ring and sleeve (ground) contact on the ZLM switch jack, or by using a
mono 3.5mm jack (or dummy plug) to switch on ZLM mode.
Bypasses windows internal kernels offering lower latency (delay) and bit
identical transfer between the software application and the sound card‘s audio
converters. It is NOT available with all version of the PUC² family.
