HOURS X DAY SPL EXAMPLE

Small gig

8 6 4 3 2 1,5 1 0,5 0,25 or less

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 preamplifiers 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 lowcut 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!

3. QUICK START

This is the fastest way to get something out from your MP8D, if you have a keyboard and a microphone.

a. Keep the Power switch in OFF position. b. Turn down all the GAIN controls. c. All the switches must be in OUT position. d. Plug-in a microphone on Channel 1 MIC input. e. Connect the output of Channel 1 (use the INSERT socket) to your mixer. f. Sing or speak into the microphone with normal volume and adjust the channel LEVEL

control of half. g. Connect the AES/EBU output of your MP8D to a digital input of your HDR or DAW. h. Connect the ADAT pipeline of your MP8D to your ADAT Recorder. i. If you are using a dynamic microphone, keep the +48V (phantom power) switch in OFF

position. If you are using a condenser microphone, press it in ON position.

j. Sing something into the microphone with normal volume and adjust the GAIN, so that

the -20 and 0 LEDs light continuously. CLIP LED should flash occasionally or not at all.
