1. INTRODUCTION
Thank you for your purchasing the MP8D microphone/instruments preamplifier with
digital output. It is just one of the many  LTO products that a talented, multinational
Team of Audio Engineers and Musicians have developed with their great passion for
music. The MP8D ESOTAR has been built with no economy thinking at the challenges
of the digital era. It is made in road-worthy and durable package for live and recording
studio applications. The MP8D ESOTAR includes the same high-end microphone pre-
amplifiers used in the renewed  LTO Typhoon large format mixing console. Their
performance rivals with the world's best preamplifiers that cost three or four time
more. The MP8D ESOTAR is equipped with both analogue and digital outputs, and
therefore, it can be used great flexibility with analogue Live Consoles, Digital Audio
Workshop and Hard Disk Recording. Channel 1&2includeahigh-impedance instrument
input so that you don't need an external D/I box to connect an electric guitar or bass
to these inputs. Then, each of the eight channels has a phantom power switch, a low-
cut switch and a GAIN control. The available gain is 60 dB, so a Line switch is not
needed. The sample rate selector allows you to select 44.1k, 48k, 44.1k 2, 48k 2,
44.1k 4, 48k 4 or sample rate, or to use an external clock. MP8D ESOTAR features
an outstanding 128 dB of S/N ratio; a frequency response extended to 200 kHz and
a THD of 0,007%. The characteristics make MP8D ESOTAR to be one of the most
transparent and advanced Microphone/Instrument preamplifiers available today.
Enjoy your MP8D ESOTAR and make sure to read this Manual carefully before operation!
