REAR VIEW - HEAD VERSION

This 1/4” jack provides a signal derived from the speaker jack. Perfect for using the RECT-O 50 as a master pre- amp, or additional power amps may be connected for more power when needed. Some players use this to derive an FX Send Signal

and go to other amps for their wet sound.

SLAVE SPE

NOTE: Once a signal is taken from the SLAVE, it can not be inserted back into the FX Loop Return jack or a feedback loop will occur. Much like holding a microphone into the PA system’s cabinets...a loud high pitched squeal will occur.

OUT 4 OHM 4 O

(TO EXT. PWR AMP)

SPEAKERS: Sensitivity to speaker mismatching in regards to ohmage differences is low, hence no damage to the amplifi er will occur. However, very low ohmage loads will cause the power tubes to wear faster. The RECT-O 50 (combo only) is equipped with a Celestion Custom 90 single 12 inch - 8 Ohm speaker, but as you can see, other speaker

When using two 8 Ohm speakers, connect each of them to the 4 Ohm speaker jacks that are provided, this will equal a 4 Ohm load which is the proper impedance required when using this particular speaker confi guration.

HEAD VERSION

BIAS SELECT: Your RECT-O 50 amplifi er was designed with versatility in mind. So to add to the already awesome array of on board features...we felt it essential that these new RECT-O 50 Series 2 amplifi ers be able to adapt their power output section to use the other classic pentode power tubes, the British style EL 34. These tubes are largely responsible for the signature sound of many immediately identifi able and wonderful sounding amps created in Great Britain

and used on some of the best recordings to date.

TUBES IN USE

The nature of their sound is usually brighter in the extremely high frequencies...some players fi nd this almost thin at fi rst. However, afi cionados of the EL34 sound know that nothing has the lushness of harmonics or spread like a power amp using EL34’s. In truth EL34’s do focus in on a region of upper harmonics that 6L6’s reproduce, but not really enhance, in the same way the EL34’s do.

This characteristic is sometimes preferred for sounds that range from a soft clip that would be used for
