Παιδιά ευχαριστώ πολύ.
Και να φανταστείς haryy πως την ιστοσελίδα αυτή την γνώριζα.
Αχχχ Γεράματα !!! :lol: :cry:
Τώρα θα ήθελα κάποιος να μου πεί
που θα ρυθμήσω το knob του impedance στον TwinTrack Pro.
Παραθέτω ένα κομάτι από το μάνιουαλ του TwinTrack Pro
VARIABLE IMPEDANCE: IN DEPTH EXPLANATION
Dynamic moving coil and condenser microphones
Almost all professional dynamic and condenser microphones are designed to have a
relatively low nominal output impedance of between 150 and 300 when
measured at 1 kHz. Microphones are designed to have such low output impedance
because they are then less susceptible to noise pickup and they can drive long cables
without high frequency roll-off due to cable capacitance.
The side-effect of having such low output impedance is that the mic pre-amp input
impedance has a major effect on the output level of the microphone. Low pre-amp
impedance loads down the microphone output voltage, and emphasises any frequencyrelated
variation in microphone output impedance. Matching the mic pre-amp
resistance to the microphone output impedance (e.g. making a pre-amp input
impedance 200 to match a 200 microphone) still reduces the microphone output
and signal to noise ratio by 6 dB, which is undesirable.
To minimise microphone loading, and to maximise signal to noise ratio, pre-amps
have traditionally been designed to have an input impedance about ten times greater
than the average microphone, around 1.2 kto 2 k. (The original ISA 110 pre-amp
design followed this convention and has an input impedance of 1.4 kat 1 kHz.)
Input impedance settings greater than 2 ktend to make the frequency-related
variations of microphone output less significant than at low impedance settings.
Therefore high input impedance settings yield a microphone performance that is more
flat in the low and mid frequency areas and boosted in the high frequency area when
compared to low impedance settings.
Δηλαδή 10 φορές πάρα πάνω, πάμε στα 3000 Ω, σωστά;
Το TwinTrack Pro έχεια αντίσταση από 60 ως 3k,
άρα πρέπει να το βάλω στο τέρμα; 8O
Και αν το βάλω αλλού τι θα γίνει; :?
Επίσης ας μου πεί κάποιος αν το γεγονός πως το μικρόφωνό μου
έχει αντίσταση 300 Ω είναι καλό ή κακό.
