IMPORTANT: The SPEAKER OUT jack has an open load protection feature. If no cable is connected
to this jack the Power Station will remain locked in BYPASS/STANDBY mode regardless of the
front panel Standby switch setting. This is done to prevent potential damage to your valuable
vintage amp should the speaker cable become disconnected while in Bypass mode. Use only a
standard mono (tip/sleeve) 1/4“ phono plug.
11. CABINET IMPEDANCE – When the speaker jack is connected, simply set the impedance selector
switch to match your cabinet.
IMPORTANT: The 2/4Ω amp and speaker setting is designed to be safe and compatible with all
vintage 2Ω and 4Ω amplifiers. Because a reactive load is not an actual speaker, the impedance
behavior of the load will not vary as wildly as an actual speaker and will therefore maintain a safe
and stable load for your treasured vintage amps at this low impedance range. Even so, we do
recommend that your power tubes are in good condition when using this device.
12. FOOTSWITCH JACK – Controls front panel Select function (tip) and FX loop bypass (ring) using
any standard 2-function TRS latching footswitch or remote switch function provided by your pre-
amp, modeler or effects switching device. Shielded or non-shielded cable is suitable for this appli-
cation (Footswitch is sold separately).
13. GROUND LIFT – This switch separates the internal circuit ground from chassis and power ground
in order to eliminate possible ground loops between the Power Station and the load amplifier
connected to the AMP IN jack. Select the position which yields quietest operation. With a properly
wired AC outlet and factory supplied AC cord, this switch may not produce a noticeable difference.
14. MAINS FUSE – Protects the amplifier from electrical faults. Replace only with type and rating spe-
cified on the rear panel of your amplifier.
15. AC MAINS INPUT – Connect to a grounded outlet in accordance with the voltage and frequency
specified on the rear panel of your amplifier.
USE ONLY THE FACTORY SUPPLIED CORDSET OR A UL APPROVED EQUIVALENT TYPE
USING SILENT MODE
Silent Mode allows you to use the Power Station as a silent adjustable reactive load for quiet direct recor-
ding or when sending a live amp signal to front of house with no speaker cab connected. In this mode it is
not necessary to power up the Power Station. You don’t even need to plug in the power cord. The Voicing
switches, Low Pass Filter switch, FX Send (along with the FX Level switch), and the Balanced and Unba-
lanced Line Outputs all operate with no AC power applied.
TUBE FUNCTION AND LOCATION
Power and phase inverter tubes are mounted horizontally near the back of the unit. The power tubes are
factory biased for optimum performance. No provision for internal or external biasing is provided. To insure
that the Power Station will remain within safe temperature operating limits, the bias must not be modified
or tampered with. Doing so will immediately void the warranty. Tube types are factory selected for superior
performance, consistent tone quality and reliability. Power tubes are factory tested and matched. For best
performance, replace only with factory recommended tubes.
