The Loop-Thru jack is a "send" and "return" all in one jack. As a patch point it puts the
connected effects in series with the preamp and power amp sections of the YCV80/80Q. To
connect an effect here, use a "Y Insert" cable configured as follows; ¼-inch stereo (TRS) male
to two ¼-inch mono male jacks. Our model PC-6ISPH can be used for this purpose.
Footswitch Jack
21
Connecting a footswitch to the ¼-inch TRS Footswitch jack deactivates the control panel
mounted Channel Select and Boost switches. These functions are then activated exclusively
by the pedal. The included footswitch features dual-latching switches, each with a separate
LED indicator.
The switching is accomplished with internal relays so there is no audiable noise flowing
through the footswitch cable. Footswitch-induced noise is never an issue. The YCV80 is
compatible with most aftermarket latching dual-footswitch pedals.
External Speaker Jack/s
22
The chassis mounted ¼-inch jacks allow convenient connection of a 4 ohm external speaker
cabinet. If you disconnect the internal 12 inch Celestion® speakers, you can connect up to
two 4 ohm external cabinets.
Phones/Line Out & XLR Balanced Line Out Jacks
For maximum versatility, The YCV80/YCV80Q has both ¼-inch and XLR Line Outs. The
¼-inch output also doubles as a headphone jack. This Phones/Line Out jack can be used with
any stereo headphone. The signal sent form these outputs are post-preamp and pre-master.
Note that the output signal is affected by all tone controls, including reverb, but not the Master
Volume. For practicing silently, don't forget to disengage the speaker outputs by depressing the
Speaker Defeat button.
Headphone Jack & Speaker Defeat
The headphone jack can be used with any stereo headphones. The headphone signal
is post-preamp and pre-master which means the signal is affected by all controls
(including reverb) but not the Master Volume. For practicing silently, don't forget to
disengage the speaker outputs by depressing the Speaker Defeat button.
Replacement Tube Selection & Bias
This amplifier features Yorkville's auto-balancing / auto-matching tube biasing technology.
As a result, when the time comes to replace the tubes in your Yorkville amplifier, there is no
need to pay a premium for a matched set – nor does the bias need to be adjusted when you
use a different brand. We make no claims as to which brands of tubes might sound best,
but with auto-balancing / auto-matching, you are free to experiment without any need for
concern that the amplifier or tubes will be distressed. Please note that auto-balancing / auto
matching cannot fully compensate for different types of tubes - 6L6/5881s versus 6CA7/
EL34s, for example.
Please note that although auto-balancing / auto matching allows you the freedom to select
unmatched tubes from a variety of manufacturers, it may not be able to fully compensate for
the use of a non-equivalent model or part number of tube – 6L6/5881s versus 6CA7/EL34s, for
example. Use of non-equivalent tubes may result in unpredictable performance.
