MosValve 962
Operation Notes
•
This amplifier was designed primarily for musical instrument amplification. It is an addition
to your audio rig which will add warmth and definition to your sound.
•
Use MosValve with any preamp capable of producing 450 MV into a 50K load (Virtually any
preamp in existence.)
•
Use with speakers or cabinets capable of at least 80 watts RMS continuous power. Re-
member that MosValve can typically produce in excess of 100 Watts/channel under typical
conditions common on stage today. At least 100 Watt speakers or cabinets are therefore
highly recommended if you intend to use the amp at high power output. MANUFACTURER
IS NOT RESPONSEBLE FOR ANY SPEAKER FAILURE WHILE USING THIS EQUIP-
MENT.
•
This is a stereo power amp. Mono operation is switchable (both channels. input bridged)
with the use of single input plugged into Channel A. Stereo operation is automatic when an
additional input is plugged into Channel B.
•
It is often advisable to use only one channel for mono (for example, if you have only one
speaker cabinet), as the MosValve can produce over 100 Watts with only one channel
driven. Use Channel A and set Channel B controls to "O." NOTE: It will not damage Chan-
nel B to have no speaker plugged into it while using only Channel A.
•
NEVER attempt to power bridge the two speaker output channels together. NEVER parallel
or series them into one speaker or cabinet. If power from both channels is used, ALWAYS
use at least two separate speakers (one per channel) or separate speaker cabinets per
channel. ALL WARRANTIES WILL IMMEDIATELY BECOME VOID IF ANY ATTEMPT AT
POWER BRIDGING, OR PARALLEL / SERIESING OUTPUTS ARE MADE!!
•
A certain amount of heat during operation is normal. The MosValve amplifier is biased in a
manner in which even when idling there is some heat present. It is best to keep the ampli-
fier towards the bottom of the rack (coolest air) and avoid obstructions to the vents in the
case.
•
Never load the speaker outputs with less than 4 ohm loads. These can be single speaker
cabinets per output or a combination of two cabinets per output. Examples of cabinet com-
binations:
Per Channel: One 4 Ohm (or higher) or Two 8 Ohm (or higher)
