..Alesis M1 Active Mk2 zabluda?..

[lesha]

evo nekih podataka:

Hardware DSP 100MIPs custom audio DSP.
DSP - 32-bit integer math with a 67-bit accumulator

ANALOG LINE INPUTS

Type Unbalanced, low-noise input circuitry
Level Consumer: -10 dBV nominal, 6.4 dBV maximum
Frequency Response 20 Hz - 20 kHz: +0.20/-0.10 dB
THD + N -100 dB (.001%) 1kHz at -1 dBFS
SNR 111 dB (A-weighted 22kHz BW)
Dynamic Range 111 dB (1kHz, A-weighted, 22kHz BW)
Channel Crosstalk < -120 dB, (1 kHz signal at -1 dBFS)
Input Impedance 3.3K ohm

ANALOG LINE OUTPUTS

Type Unbalanced, low-noise circuitry
Level Consumer: -10dBV nominal, 6.4dBV maximum
Frequency Response +0.05/-0.10 dB, (20 Hz - 20 kHz)
THD + N -100 dB (.001%) 1kHz signal at -1dBFS
SNR 116 dB (A-weighted, 22 kHz BW)
Dynamic Range 116 dB (1 kHz, A-weighted, 22 kHz BW)
Stereo Crosstalk < -109 dB, (1 kHz signal at -1 dBFS)
Output Impedance 560 ohms

posto nemam mixer, na koliko da stavim monitor i main mix level?

u pitanju su nebalansirani i/o

hm... to je -10dBV
da li Alesis ima nebalansirane ulaze?
kakve su njegove karakteristike za input?

Nista o osetljivosti ulaza, valjda je +4dBu... kako si razbalansirao konekciju... presao sa nebalansiranog na balansirani ulaz?

Na kraju, ako nista ne uspemo.. ocepi ti njega do kraja i utisavaj na karti...

ili nadji neki master volume, mozda ti ne bi bio los neki di-box sa atenuacijom... ima li tako neceg da se kupi za male pare?

ima kombinovani ulaz - TRS balanced/unbalanced / XLR

ja sam koristio nebalansirani TRS..

zanima me koliko bi trebao da utisam gain na softverskom mixeru bez boxa..

Pa tako da ti prija slusanje... probaj pa javi... nema nacina da sada procenim koliko decibela treba nesto utisati .... najbolje probaj pa kazi koliko si morao da utisas...

Ja licno gotovo nikada ne smanjujem nivo preko miksera kartice kada radim svoju muziku ili miks, jer za to ne vidim potrebu, cilj mi je da iz same kartice izlazi ceo dinamicki opseg muzike koju radim. Koristim kombinaciju rme hdsp9632 i alesis, i jacinu sam na samom Alesisu podesio na vrednost oko 6. Preporucujem ti, ako vec zelis da koristis alesise na visoj jacini, da koristis analogni atenuator, i to A-design ATTY:http://www.adesignsaudio.com/atty.htm. Za te pare (oko 120 e ili i manje) nema boljeg resenja, a imas sve sto ti treba za transparentno slusanje, a da zvuk kartice preko miksera podesis na maksimum. Na nesrecu, ne znam gde se moze kupiti kod nas, ja sam ATTY kupio preko interneta.
A to sto mp3 i zvuci iz Swinjdowsa zvuci distorzirano, mislim da je vise problem samih fajlova nego tvog audio sistema.
