Setting Up and Using Your Hartke A SERIES Combo Bass Amplifier
when no compression is being applied, will go out whenever small amounts of compression are being applied and will flash or light steadily red when limiting (severe compression) is being applied. 9. Test the headphone output by turning the Volume control to its minimum (fully counterclockwise) position and then connect a standard stereo headphone to the frontpanel Phones jack. While playing your bass, slowly turn the Volume control up�you should hear sound from the headphones and none from the connected speaker. We recommend the use of large size headphones (those with large transducers) for optimum bass reproduction. 10. If you need to connect the A Series to a PA system or a recording mixing console, connect a cable between the rear-panel Direct Out output and a Line-level input on the mixer. (See C on page 6 in this manual for more information on the use of the A Series Direct Out). 11. If you�re using a professional external signal processor that has Line-level inputs and outputs, turn your A Series amp off momentarily and then connect a standard audio cable between the rear panel Preamp Out jack and your effects processor input and another standard audio cable between the Amp In jack and your effects processor output (if required, multiple effects processors can be daisychained together, output to input). Then turn the A Series amp back on and play your bass while adjusting the controls of your effects processor(s). For best results, set both the input and output gain of the connected effects processor(s) to 0 dB (unity gain), so that there is no increase or decrease in level whether the effects are switched in or out. If you encounter difficulty with any aspect of setting up or using your Hartke A Series Bass Combo Amplifier, you can call Samson Technical Support (1-800-372-6766) between 9 AM and 5 PM EST, or contact your local distributor.
