frequency
section features 12 dB of cut or boost with a bandwidth approximately 1 octave wide. The center
frequency of this filter is approximately 1kHz, peaking curve. This filter is typically (but not always) used to reduce
or remove offending frequencies in an instrument’s pick-up response, or the nasal sound in a vocal. Removing only
the minimum amount necessary will yield the most acoustically rewarding results. Occasionally, you will find need
to use the mid section in “boost” mode, particularly common when adding higher mids (bite) to an otherwise dull
instrument, or adding low mid “body” to an otherwise thin sound. Spend some time experimenting so that the
process becomes creative as well as corrective.
MASTER VOLUME
–
The master volume control adjusts the overall volume of the mix of channels 1-5 and the
Alesis™ digital effects return. Typically, best results are obtained when this control is operated between the 9:00
and 3:00 positions.
DIRECT OUTPUT
–
The UC-5 contains a “post effects” and “post master volume” XLR balanced direct output.
This output is completely phantom power and short circuit protected. The ground lift switch allows disconnection of
the pin 1 ground from the UC-5 to eliminate ground loop hum. This output will not be active unless the master
volume is turned up. The XLR balanced output is “hot” mic level, rated at –30 dBv. This configuration allows the UC-
5 to drive very long cable lengths (250+ feet) without problems or added noise.
PREAMP OUT/POWER AMP IN
-
A signal patch point is provided between the master output preamp and
the input to the power amp section. This signal point is unbalanced and operates at +4dBv. It is a convenient insert
point for graphic or parametric equalizers and signal compressor/limiters.
POWER AMPLIFIER
–
The UC-5 features our DUAL OUTPUT DESIGN which contains 2 separate advanced
monolithic power amplifier circuits that are fully protected against overloads, short circuits and thermal faults.
Output is rated at 100 watts per channel into 4 ohms (dual mode), and 200 watts into 8 ohms (bridged mono
mode) with excellent overload recovery characteristics. A unique feature of this amplifier is the “on silicon”
temperature sensor that automatically tracks and adjusts the amplifier’s operating and protection parameters, a
very cool feature that increases product reliability 10-fold over conventional designs. With the Mode Switch in the
dual position only the dual speaker jacks are active. With the Mode Switch in the bridged mono position only the
bridged mono jack is active. Driving speaker loads below the amplifier’s rated minimum load (4 ohms each channel
in dual mode and 8 ohms in the mono bridged mode) will result in distortion and possibly intermittent operation as
the protection circuits are activated. There is an internal cooling fan to keep heatsink temperatures at safe levels.
HEADPHONE JACK
–
The UC-5 is equipped with a headphone jack that will drive all known headphones to a
reasonable level. Use caution when monitoring at high volumes as hearing damage may result.
POWER INPUT
–
The UC-5 is shipped from the factory with a standard IEC type power inlet connector and the
appropriate power cable for the market the amplifier was shipped to. The power transformer is a high quality
universal input toroidal type, (115/230 volt, 50/60 Hz) with a voltage selector switch located above the inlet
connector. Be sure that this switch is in the correct position (matching your local power system) BEFORE
connecting the UC5 to the power source. There is an AC mains fuse (with a spare fuse included!) located in the
small slide out tray located on the IEC power inlet connector. Always replace with the correct value fuse as
indicated on the fuse chart located on the back of the amplifier.

SPEAKER CONFIRGURATION
–
This model is shipped with our GBE 1241C 200 watt
woofer and GBE 4941 compression tweeter which produces full range high output response. The impedance load
is 8 ohms.
