FRONT PANEL FEATURES

TUNER INPUT

The Tuner Input jack allows you to connect an instrument tuner and tune up without having to unplug and go back and forth from amp to tuner. This feature is totally isolated from the rest of the preamp and will function regardless of the settings on the front panel. Being isolated on a side chain avoids loading down of the instrument, which can result in a loss in dynamic range.

To use this feature, connect a shielded patch cable from the Tuner Input jack to the input on your instrument tuner. Turn the amplifier on and you’re ready to go. If you do not want to monitor your sound during tuning, either turn down the Master Volume completely or turn the Speaker On/Off switch to the “Off” position.

PASSIVE/ACTIVE INPUT JACK

This input can and should be used if your instrument contains passive electronics (i.e., no built-in preamp). Some instrument pickups use batteries for operation and will work perfectly using the Passive/Active input. Generally speaking, this input should be used if your instrument puts out a maximum of 1 volt RMS or less. Consult the owners manual for the instrument or ask the manufac- turer if you are unsure.

Note: If you hear a small amount of distortion and neither the Preamp Clip LED nor the Power Amp Clip LED are activated, try using the Active Input jack.

If you would like to overdrive the first tube stage, this can be accomplished by using a preamp between your instrument and the Passive/Active input. To obtain optimum sound when trying this, make sure the Preamp clip LED is not activated. If this occurs, turn down your Gain control. The first preamp stage is not monitored by the Preamp clip circuit for this reason.

ACTIVE INPUT

The Active Input jack should be used with instruments that contain a built-in (on-board) preamp that put out a signal over 1 Volt RMS. Some really "hot" pickups installed in your instrument may find the Active input more compatible. Let your ears be the judge.

Note: The input impedance of the Active Input jack is 82kohms. Using the Active Input with pas- sive instruments (active instruments will always employ a battery) may result in a loss of high- end transients. Players who roll off their high end starting at about 2 or 3kHz may find this input more to their liking.

If you hear distortion when using an active instrument in the Active Input jack, check your battery! Also, make sure that none of the clip indicators are lit.
