-Microphone & Rotor Output-
*
The PRO-3X is a mechanical device, background/wind noise will increase on fast speed.
Play the PRO-3X at 50% volume or more for best signal to noise ratio and to minimize bleeding
of adjacent instruments into the horn microphone.
-PA systems and Recording-
PA Note
- If your
Keyboard amplifier
is connected to a PA system, connect the PRO-3X
’
s Sim
output to your amplifier. The simulator will be sent to the PA from your Keyboard amplifier.
Turn the
“
Mix
”
control fully to
“
H
”
. The horn microphone is then available alone at the Mix
output connector for send to the PA. The house sound Engineer will then set the balance of the
horn with the Low Rotor signal from your Keyboard amplifier
Built in microphone
The PRO-3X contains a dynamic microphone element for convenient
connection to a PA system. The microphone is adequate for most live performance venues.
Critical recording
should always be done with external microphones in stereo.
Mono PA with internal microphone
–
Adjust the mix output for balance of horn and low
rotor send to a mono PA system or recording channel.
Mono PA with external microphone
Place the microphone by a front opening on the PRO-
3X. Sound will vary with distance and location. Start with a distance of about 1
”
from the
grill cloth and try different positions. Connect the microphone to a channel strip and the low
rotor simulator output to a second channel strip. Pan both to center.
Stereo PA
and studio recording
- Use external microphones in stereo, one on the front left
and front right grill openings of the PRO-3X. Connect each microphone to a channels strip
and pan hard left and hard right respectively. Connect the low rotor simulator output to a
channel strip and pan center. Mix the volumes to preference at the PA mixer.
-Recording and PA EQ-
The crossover of the horn/low rotor is at 800 HZ 18Db/oct. Best signal to noise is obtained by
playing the PRO-3X at least 50% volume or more. The horn channel strip(s) should be cut
below at about 400 Hz. The Low Rotor output should be cut above 1.5 Khz If your channel
strip does not have full capability, try turning down the Bass on the Horn and Treble on the
Low Rotor simulator. Listen carefully while making EQ adjustments, preferably done at
performance volume levels.
