[. . . ] The features included in the BXR 60 will provide a forum for almost every conceivable playing style, from "traditional" to "contemporary", and those yet to come. The preamp section of the BXR 60 features two inputs of differing sensitivities, allowing for the use of a wide variety of input sources and levels. The 4-band EQ allows for up to 12 decibels of boost or cut in 4 bands between 80 Hz and 6KHz. [. . . ] MID NOTCH switch - removes midrange, making the amp sound "punchy". EQUALIZER - allows adjustment of the tonal characteristics of the amplifier. Each control provides a 12 dB boost or cut to the low, low mid, high mid, and high frequency ranges. TAPE IN - Plug-in connection for any line level (500mV) stereo or mono signal. This signal is mixed into the power amp along with the instrument signal from the preamp. It has fixed gain and is unaffected by any of the front panel controls; however the signal will be affected by any device inserted between the PREAMP OUT (item G) and the POWER AMP IN (item H). It is useful for patching in a CD or tape player, rhythm machine or other signal source to be used as an accompaniment for practice or performance. The output level control of the external signal source is used to control its own volume while the front panel VOLUME (item D) control is used for the instrument in order to obtain a balance. G. PREAMP OUT jack -This jack provides an unbalanced mono output signal from the preamp. This output can be used with the POWER AMP IN jack (item H) as a patch point for mono effects devices. It can also be used to provide a signal to a recording or sound reinforcement mixer. In addition, this output can be used to drive another BXR 60 used as a slave amp. This is done by connecting a standard guitar cord from the PREAMP OUT jack of the master amplifier to the POWER AMP IN jack (item H) of the slave. J. H. POWER AMP IN jack - This unbalanced input goes directly into the power amp. This jack is useful when using the effects loop feature, or when using the BXR 60 as a slave amp.
