control instead. This avoids running the load resistor of the headphone circuit unnecessarily hot. To mute the speakers in the second-
ary room while the main room remains active, either turn off the secondary amplifier or turn the Level Set to zero. We recommend
turning off the second amp so that your favorite inter-room level balance stays put by leaving the Level Set at the predetermined
setting.
Please note that this is merely a basic multi room scenario - you won’t be able to play back two different musical programs
simultaneously.
You may be surprised to note that the power cord of the TIGRIS unplugs from the main chassis. This allows you to experiment with
after market power cords which can result in surprising differences. It also makes for easier installations. Make sure
the A.C. switch is in its off position before you plug in the A.C. power cord. If all the component connections have now
been made, you should connect the TIGRIS to your electrical wall outlet, power strip or line conditioner. Check
that your line conditioner is not a current-limiting device.
Above the Front Panel, you’ll find the primary ON / OFF toggle switch in the left-most position. Upon power-on, the LEDs will light up
to confirm status - dim in WARM mode, bright in OPERATE mode.
The TIGRIS should be fully powered down and unplugged during severe thunder storms that might
cause power failure and line surges, as well as during vacation periods. With the TIGRIS connected to
your power source, you should now turn on the A.C. Switch. The front-mounted push button switches
should still be in the WARM position.
The TIGRIS allows instantaneous start-up by switching from WARM to OPERATE. Think of the WARM feature as an idle current that
operates the tubes in standby at highly reduced Hv. This is similar to an advanced rheostat that keeps halogen bulbs under current
even when the lights are extinguished, thus extending the bulbs’ life span. The status LEDs will turn from dim to bright whenever
operate is engaged, and will fully extinguish only when the A.C. ON / OFF switch is turned off.
Whenever you have to change and disconnect interconnects, turn the TIGRIS off. There is enough
Hv in the WARM position to reproduce signal at much reduced output level - this could cause minor
feedback noise to your speakers if you unplugged interconnect cables in WARM mode.If you listen a
lot, leaving the tube circuitry in the WARM mode actually extends the life of the active components
because the sudden turn-on / turn-off power fluctuations are avoided. The load on your electric bill is
negligible, and you won’t have to wait for the tubes to warm up! *
If, on the other hand, you listen rarely, turn on/turn off wear is not an issue, so you should power down
the amplifier after each listening session. Like its pro-music brethren, we designed the TIGRIS ex-
pecting a certain amount of unintentional abuse, so you won’t have to concern yourself with handling
your new amplifier with velvet gloves.
* During summer months, you may want to shut down the amplifier when you don’t listen to it - especially in smaller rooms,
this will ease the burden on your air conditioner. If your system is fully hooked-up now, the A.C. Power ON and the Standby
switches in the WARM position, you are about to begin your first listening session. One final step remains - setting the grounding
switch appropriately.
