Preamp Out (19)/ Poweramp In (18) Jacks

The PREAMP OUT and POWERAMP IN jacks are available to insert

professional line-level effects devices. This type of effects loop is best

described as a 'hard insert' or 'break' type of loop. PREAMP OUT

connects to the input of your effects device. POWERAMP IN connects

to the output of your effects device.

When connected to a professional line-level effects device, the amplifier

breaks the connection between the preamp and poweramp. Signal levels

and mix of the DRY/WET signals are controlled by the effects device.

Take care to optimize your gain structure in order to retain a high-

quality, low-noise signal. When not connected, there is no break inter-

nal to the amplifier allowing the amplifier to operate as designed.

This type of insert effects-loop is the best type for retaining the purity

of the amplifier performance as there are no buffers or level matching

circuitry to color your sound. The trade off is acknowledged to be less

versatile in certain circumstances. However, the purity of the sound

quality is the overriding requirement.
