long as your speaker cabinet can handle the peak levels. Adjust the controls slowly, and use com- mon sense.

Midrange Controls

Your 350x comes equipped with two different controls for setting the amount of midrange present: one for boosting and cutting the level of midrange, and another for setting the specific midrange frequency that will be adjusted in level.

Midrange Level Control

The Midrange Level control cuts or boosts the frequency set by the Midrange Frequency control. Starting at mid-position, turning the Level control counter-clockwise cuts the desired tone. Turning the Level con- trol clockwise boosts the desired tone (set by the Midrange Frequency control). When the level control is set at mid-position (“center-click”), turning the frequency control will have no effect on the sound.

To find the midrange area you are looking for:

1.Adjust the Midrange Level control to the full boost or cut position.

2.Rotate the Midrange Frequency control until the desired area you wish to cut or boost is found.

3.Adjust the Midrange Level control to the desired amount of cut or boost.

Midrange Frequency Control

The Midrange Frequency control sets the area that is to be cut or boosted by the Midrange Level con- trol. If the Midrange Level control is set at mid-position, turning the Frequency knob will have NO affect.

Some hints: If you need to “cut through” the band a little more, try boosting 200 to 400 Hz. If you like a more transparent or “scooped” sound, try cutting at 800 Hz. The midrange controls are especially use- ful in controlling fretless basses and their inherent qualities.

Treble Control

The Treble control employs a shelving-type circuit and boosts or cuts the high frequencies (and their sub- sequent octaves) +/–15dB from about 2kHz to 14kHz. Starting at mid-position, turning the control counter- clockwise cuts the treble response, while turning the control clockwise boosts the treble response.

Effects Blend Control

The Effects Blend Control “blends” the signal sent from your instrument with the signal coming from your EXTERNAL effects unit. (In other words, it has nothing to do with the SubWave™ effect onboard your 350x.) With the Effects Blend fully counter-clockwise (“DRY”), no signal from your external 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 external effects unit provides. If your external 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 reduc- ing 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 guide).

Limiter/Compressor Circuit

The Limiter found in the 350x is a soft knee type limiter. The Limiter circuit is located after (post) the Master Volume and before (pre) the power amplifier. Therefore, the Limiter is driven by the Master Volume control. Its threshold (starting point) is preset by the factory so that the user can get maximum overall apparent volume without unduly overdriving (or “clipping”) the power amplifier, which can eventually dam- age the unit’s internal circuitry. This can also be helpful in preventing speaker damage when running your system at high volumes.
