THE SOUND THAT CREATES LEGENDS Twin,Amp Owner s Manual P/N 047775 TYPE: PR266
Introduction The Fender TWIN™ is the next step up in the evolution of High Performance instrument amplification. The new TWIN is a direct descendent of classic tube amps such as the Fender Twin Reverb®, and 410 Bassman®, which have shaped today’s world of guitar amps. The features of the new Fender TWIN provide flexibility rarely found in tube amplifiers.
Twin Front Panel Functions (Fig.1) A. INPUT 1 — A high impedance, high sensitivity plug-in connection for instruments. B. INPUT 2 — A plug-in connection for instruments. This input exhibits less input impedance and sensitivity than INPUT 1, making it useful for guitars that have active pickups. This input will provide a darker tone if used with guitars that have passive pickups. Note: INPUT 1 and INPUT 2 are inputs for both Channel One and Channel Two. C.
Fig. 1 Fig. 2 If a fuse blows, it should be replaced only with a fuse in accordance with the listing at the fuse holder. If the amplifier repeatedly blows fuses, it should be checked out by a qualified technician. UNDER NO CIRCUMSTANCES should a fuse of a different type or higher rating, or a fuse bypass be used, as this could damage the equipment and present a serious safety hazard. F. EFFECTS SEND JACK — Provides an unbalanced output signal from the preamp, pre-reverb. It is used to patch into effects.
CH. 1 L. OUTPUT BALANCE ADJUST — Used in conjunction with the BIAS TEST POINTS (item K) to set the balance between the push/pull tube sections of the power amp. See output Tube Bias Adjustment Instructions below. Output Tube Bias Adjustment Instructions — 1. Turn on the amplifier and let it warm up for at least two minutes with the STANDBY SWITCH (item C) in the ON position and the OUTPUT SWITCH (item D) in the OUTPUT HIGH position. 2.
of the slave amps such that they NEVER clip with full output from the Twin. Here’s why: Since the signal at the BALANCED LINE OUT is derived directly from the output transformer, the signal is a replica of the voltage present at the speakers in the Twin. If the output of the slave amps never clip, then the voltage at the output of the slave amps will also be a replica of that on the speakers in the Twin. This will preserve the Twin sound. As for the 300 watt minimum rating...
