Genz-Benz 200 Stereo Amplifier User Manual


 
MASTER STATUS LED INDICATORS - Output status LED’s are provided to indicate Signal present and
Clipping. The Green LED monitors the pre Master Volume output signal from the preamp before the power amp
section. The Red LED indicates Clip/Limit and indicates that the maximum power threshold has been crossed and
the internal “soft-clip” limiter is active. Driving the amp 6db beyond this point will cause gradual clipping.
CHANNEL INSERTS / EFFECTS LOOP – The Shenandoah™ 200 is equipped with insert points on each
channel AND on the left and right main signal paths. These points are handy for inserting compressors and
dedicated digital effects processors. Signal is line level and unbalanced.
DIRECT OUTPUTS – The Shenandoah™ 200 contains the most comprehensive direct output section
sense” when connecting with other equipment. The ¼” unbalanced outputs are true professional line level (+4 dbv)
long cable lengths (250+ feet) without problems or added noise and is compatible with all commonly encountered
mixing consoles. The XLR balanced direct outputs can be “ground lifted” with the global ground lift switch. This
switch lifts pin 1 on all of the XLR balanced outputs to break ground any loops between the Shenandoah™ 200 and
a PA system (or recording) console Direct outputs are provided for each channel, pre eq, pre effects, post channel
volume (to take advantage of the dual summing inputs on each channel), and for left and right mixed outputs, post
POWER AMPLIFIER
circuits that are completely protected against overloads, short circuits and thermal faults. Output is rated at 100 watts
a very cool feature that increases product reliability 10-fold over conventional designs. An internal cooling fan is
provided for maximum heat exhaust through the front panel vents.
TUNER OUT – This jack is provided for use with all tuners that accept a ¼” input. The signal from this jack is
always present and works well with all known tuners.
EFFECTS JACK – This jack is provided for use with the 2 button DSP footswitch with comes standard with the
Shenandoah™ 200. This footswitch turns both DSP A and B programs ON and OFF. This is a useful tool for pre-
selecting programs and then turning them on or off when desired.
SPEAKER OUTPUT JACKS – The Shenandoah 200 provides 2 sets of parallel ¼” speaker output jacks.
Minimum total load is 4 ohms (2 x 8 ohm loudspeakers) on each output channel. The combo is equipped with a 10”
- 8 ohm loudspeaker and compression tweeter per side and may drive an additional 8 ohm extension speaker
cabinet per side. We offer the Shen-200 EXT L/R speaker enclosures that are a matched pair of Left and Right
imaged extension speakers that offer the same compliment of 10” woofer and compression tweeters like those in the
Shenandoah™ 200.
POWER INPUT – The Shenandoah™ 200 is shipped from the factory with a standard IEC type power inlet
universal input (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 Shenandoah™ to
the power source. There is an AC mains fuse (with a spare fuse included!) located in the small slide out tray on the
IEC power inlet connector. Always replace with the correct value fuse as indicated on the fuse chart located on the
TWEETER LEVEL CONTROLS – A Tweeter Level Control is provided on each side of the speaker enclosure
