SL-610 SYSTEM INITIALIZING PROCEDURE
Follow these steps to obtain the maximum gain before feedback without changing the tonal
quality of your program. Set up only one SOLO at a time. The following instructions are for
using the SOLO on the mains. For use with monitors, substitute monitor send and
master monitor control for input channel level fader and mixer master output. Be
sure to turn off the mains when initializing the SOLO in your monitor system.
11. Place the speakers and microphones in the positions where they will be used
during the program. Avoid placing microphones directly in front of speakers.
2. Set the mixer master output, all channel level faders, and the monitors to mini-
mum.
3. Turn on the SOLO by connecting the power supply to the SL-610. (There is no
power switch.)
4. Turn on the mixer, any signal processing equipment, and finally the power amp.
Press the SOLO's RESET button until the LEDs stop flashing to clear out filters
set previously.
5. If you are using a graphic EQ, adjust it only for the desired tonal qualities. DO
NOT NOTCH FOR FEEDBACK.
6. Be sure the SL-610 is in active mode. The "BY" LED will light green to indicate the
SL-610 is active and red if it is in bypass mode.
7. To set the input channel clip level, play program material at nominal levels and
adjust the mixer input gain control as high as possible without lighting either the
channel or FBX CLIP LED. This will optimize the dynamic range of the SOLO
with the channel of the mixer.
8. Set the mixer master output to a nominal level, and lower all channel levels to minimum.
9. Slowly raise the input channel level fader for the channel being set until feedback occurs.
The SL-610 should quickly remove the feedback. The first FILTER LED will then blink to
indicate a filter has been set.
10. Keep raising the level slowly until all FIXED FILTERS and one dynamic filter is set. Any
uninitialized dynamic filters will be set later if feedback occurs during the program.
11. Now lower the channel level fader slightly so that the system is not on the verge of
another feedback point. This is the maximum volume level that the SL-610 will be able to
provide. Higher levels will cause uncontrollable feedback.
Note: Once you become accustomed to this procedure, you will be able to set up your FBX in
one or two minutes.
SM-610 SYSTEM INITIALIZING PROCEDURE
SM-610 Phantom Power Selection:
Your SM-610 is delivered from the factory with the phantom power function enabled. If
you do not wish to use phantom power - for example, if your microphone will be adversely
affected by using phantom power - you may disable the function by opening the unit and
switching the jumper. Please note: Phantom power does not affect mics with 1/4" input jacks.
The majority of low impedance balanced non-phantom-powered mics are wired to ignore
phantom power. Check your microphone owner's manual for verification to avoid damage.
To defeat phantom power, follow these instructions:
1. Disconnect the power supply and remove the SM-610's MIC GAIN knob, nut and washer
on the front panel.
2. Remove the back panel's four corner screws. Gently pull the back panel and printed
circuit board assembly out of the unit.
3. Find the phantom power jumper, located between the XLR connector and the 1/4"
connector. See the following diagram. (The jumper is shown in enabled position.)
