Trans-Impedance Power Attenuator, Rear Panel

Trans-Impedance Power Attenuator

K.OVERDRIVE ON-OFF—Press IN to engage the Overdrive circuit as indicated by the LED. See Footswitch {Z}.

OVERDRIVE Off

OVERDRIVE On

L.OVERDRIVE—Adjusts the amount of signal distortion provided by the Overdrive effect.

M.TONE—Adjusts the Overdrive tone characteristics.

N.LEVEL—Adjusts the Overdrive volume output, useful for boosting gain to generate additional tube distortion.

O.TRANS-IMPEDANCE POWER ATTENUATOR—When set to FULL VOLUME, the attenuator circuit is bypassed allowing the maximum output from the tube ampli- fier. When set to SILENT, the speaker is disabled, but HEADPHONE and LINE OUT outputs may be used. At any setting beside FULL VOLUME (including SILENT) the power attenuation circuit controls the output loudness of the speaker, while preserving the tube amp + speaker “feel” and dynamics achieved through amplifier volume and playing intensity.

Rear Panel

P. f useE—Protects the amplifier from electrical faults. Only replace a blown fuse with the type and rating specified on the rear panel of your amplifier.

Q.IEC Power input socket—Connect to a grounded outlet using the supplied power cord in accordance with the voltage and frequency ratings specified on the rear panel of your amplifier.

R.p owerR—Turns the Princeton Recording-Amp ON-OFF.

S.SPEAKER OUTPUT—Connection for the speaker.

CAUTION: An 8Ω speaker must always be connected when the amplifier is ON or damage may occur.

T.HEADPHONE— / A speaker-emulated output for use with standard Stereo or Mono head- phones. Accepts a standard 1/4" plug.

U.LINE OUT—A studio-quality, speaker emulated, balanced XLR output suitable for recording or sound reinforcement applications.

V.LINE level—Adjusts the output level of the LINE OUT {U} jack. Use to accommodate the input sensitivity of your connected equipment.

W.GROUND LIFT— Press IN to disconnect the LINE OUT {U} ground pin (1) to reduce noise caused by non- standard wiring. Leave OUT for normal operation.

X/Y. SEND / RECEIVE—Effects loop jacks. Connect SEND {X} to your effects input and RETURN {Y} to effects output. Set your effects device level control (if any) as close to –10dBu as possible.

Z. f ootswitchH—Connect the included 4-but- ton footswitch using the supplied 5-pin DIN cable to enable remote on-off switching of: OVERDRIVE {K}, COMPRESSOR {H}, FX LOOP {X,Y} and REVERB {F}.

NOTE: The footswitch buttons override the corresponding panel controls.
