5.3.3 Tube ratings tables
To ascertain the rating, insert a pick into the slot to initiate read-out (see section
5.3.1). Then count the flashes and look for that number in the table below.

Rear Panel Connections and Control Features

6.1 EFFECTS ON/OFF

This port accepts the two-way Hughes & Kettner® FS-2 footswitch. Button 1
switches internal effects; button 2 the external effects loop. The FS-2's LED lights
up to indicate effects are active and the FX ON button is engaged. It does not
light up if the internal effects are bypassed or the FX ON button is switched off.
Note: The footswitch deactivates the FX ON button on the front panel! When a
footswitch is connected, it always has priority. The current status of the footswitch
is valid when switching Channels, irrespective of the switching status stored in the
preset! The front panel FX ON button now serves as an LED display indicating
the status of the footswitch.

6.2 CHANNEL SELECT

If you ever leave your MIDI board behind, this flexible fall-back connector for
footswitches will help get you through the gig. It lets you switch remotely between
two Channels, say CLEAN and ULTRA, using standard one-way footswitches
such as the Hughes & Kettner® FS-1. A two-way footswitch such as the Hughes
& Kettner® FS-2 may also be connected. In this case, button 1 is responsible for
the Channels, and button 2 is disabled. SWITCHBLADE TSC even accepts the
four-way Hughes & Kettner® FS-4 footswitch that ships with Hughes & Kettner®
Trilogy and Attax amp. It lets you switch all four Channels.
Note: The footswitch changes the Channels only, and not presets. That is, it
activates the most recent Channel settings and it does not switch effects.

6.3 FX LOOP

If you wish to use an external effect device, you can insert it into the FX LOOP.
6.3.1 FX SEND
Connect this jack to your effects processor's input jack.
6.3.2 FX LEVEL
This button cuts the FX SEND's output level by 10 dB and boosts the FX
RETURN's input sensitivity by 10 dB to match the FX Loop to the effect
device's input level. Press this button when using processors designed to handle
instrument levels.
6.3.3 FX RETURN
Connect this jack to your effects processor's output.

6.4 MIDI

SWITCHBLADE TSC is MIDI-enabled, meaning that it communicates with
other MIDI devices.
6.4.1 MIDI IN
Connect the included Hughes & Kettner® FSM 432 or any other MIDI sender
to this port so that you can select and switch Presets remotely. Though this is
a seven-pin port, you can connect a standard five-pin MIDI cable. The two
additional terminals serve to supply phantom power to the FSM 432.
Note: The FSM 432 comes with a 7-pin MIDI cable. You do not need a power
source for the FSM 432 because phantom power is provided. If you wish to use a
5-pin MIDI cable, you will however need a wall-wart. This innovative mains port
lets you connect any AC or DC adapter rated for 9 to 15 volts.
6.4.2 MIDI THRU
This port forwards signals patched into the MIDI IN port to other devices. You
can connect any external MIDI-enabled signal processor or any MIDI receiver
that you wish to switch synchronously with SWITCHBLADE TSC.

6.5 SPEAKERS

SWITCHBLADE TSC offers separate outputs for all standard impedances: You
have 1 x 4-Ω, 1 x 8/2 x 16-Ω, and 1 x 16-Ω outputs at your disposal. Always
ensure the impedance (that is, the Ω value) is correct. Mismatches can corrupt the
sound (high-impedance speaker connected to a low-impedance output) and harm
the amp (low-impedance speaker connected to a high-impedance output).
Note: You may of course connect several cabinets to one port, even if they have
different impedances. Usually speaker cabinets are connected in Parallel. Two
cabinets of the same impedance connected in Parallel have half the impedance of
a single cabinet. For example, if you have two 8-Ω cabinets, you must connect
these to the 4-Ω output. If you connect two cabinets with different impedances
(R1, R2) in parallel, the resulting resistance (R) is calculated by multiplying the
two individual resistances and dividing their product by the sum of the individual
resistances. Use the following formula to do this:
R = ( R1 x R2 ) / ( R1 + R2 )
Take as an example a one 8-Ω and one 16-Ω cabinet:
R = ( 8 x 16 ) / ( 8 + 16 )
R = 128 / 24
R = 5.33
The cabinets' impedance may never be lower than the amp's output impedance,
so this combination must be connected to the 4-Ω output. However, we strongly
advised against configuring setups with mismatched cabinets, and highly
recommend using combinations of cabinets with the same impedance!
