SWR Sound 2X10C - Manual (Page 8)

8 • WORKINGMAN’S 2X10C
EFFECTS BLEND CONTROL
The Effects Blend Control "blends" the signal sent from your instrument with the signal coming from an outboard effects unit of your
choice. With the Effects Blend fully counter-clockwise ("DRY"), no signal from your outboard effects unit will be heard. As you turn this
control clockwise, more of the effect can be heard in the overall sound. When the Effects Blend control is set fully clockwise ("WET"),
no true or unaffected signal is heard other than what your outboard effects unit provides. If your outboard effects unit has a similar
control, adjust it to the fully clockwise ("WET") position. This will avoid any possible phasing problems.
The Effects Blend circuit is similar to that used on recording consoles with the effects loop on a "side chain" to the normal circuit.
Unless the control is set to the full "wet" position, you will always get the full sound of your instrument AND get the diversity an
effects unit offers. This circuit is also effective in reducing noise generated by effects units because it is located after the gain
stages in the preamp.
The Effects Blend control functions only when the Effects Loop is being used. It is activated when a 1/4" phone plug is inserted into
the Effects Receive jack (for more information, please see the heading titled "Effects Loop" in the "Rear Panel Features" section later
in this manual).
VARIABLE LIMITER CONTROL (with defeat option)
The Limiter in the Workingman's 2x10C is designed to provide the user with maximum flexibility of control, while at the same time
provide protection for the power amplifier from clipping, a condition that can cause damage to itself and the speaker system over
time if allowed to occur.
The Limiter circuit is located after (post) the Master Volume and before (pre) the power amplifier, so the Limiter itself is driven by the
Master Volume control. You can set the threshold of the Limiter with the Limiter Control. Turning the control clockwise sets the
threshold to increase the amount of limiting, while turning the control counter-clockwise will decrease the amount of limiting. As
always, your ears will help you determine the right amount of limiting to use, as levels vary greatly from player to player due to play-
ing style, output levels of basses, EQ settings, and many other factors. This feature can also be helpful in preventing speaker damage
when running your system at high volumes.
NOTE: When listening to hear if there is distortion present in your signal, make sure you are not confusing power amp distortion
with preamp distortion. To make sure preamp distortion is not present, be sure to set the Gain Control to where the Preamp Clip LED
is not illuminating. Then you can make a clear determination as to how best to set the Limiter.
DEFEATING THE LIMITER CIRCUIT
Regardless of where the Variable Limiter Control is set, you may defeat the Limiter circuit at any time by pulling out on the Limiter
knob itself. (It doubles as an on/off switch for the Limiter.) To defeat the Limiter, simply pull "out" on the knob of this control until you
hear and feel a "click." To re-engage the Limiter, push the control back in to its original position, and the Limiter circuit will reactivate
at the threshold setting you chose originally. This may be useful in determining just how much limiting is occurring in an "A/B" type of
test. You can also hear in an instant if your limiter is set to where it is actually stopping the power amp from clipping, because if you
suddenly hear distortion that wasn't there when the limiter was engaged, that's exactly what's occurring. (This is especially key to
remember when using your 2x10C with an extension cabinet at high volumes.)
LIMITER ACTIVE LED
When the threshold (starting point) of the Limiter circuit is reached, the Limiter Active LED will light, indicating that the Limiter Circuit
is active and helping to protect your power amplifier from clipping. The Limiter LED will not illuminate when: a) the Limiter has been
defeated by pulling out on the Limiter control; b) when playing at levels not high enough to engage the circuit.
NOTE: If you have defeated the Limiter and you hear a loud, sharp distortion present in your sound − and the Preamp Clip LED is
not lighting up − re-engage the Limiter by pushing the Limiter control back in. If the distortion goes away, you were probably clipping
the power amp, which is not a good thing. Remember, the Limiter circuit is there to protect your amplifier from such a state of opera-
tion.
