This is just a description of the various jacks and switches on the back. We suggest that you might want to not rack-mount the SLAM!
until you’ve spent some time becoming familiar with the various patching and switches. Sorry, but the back panel is more complex
than most
gear and there are options galore. That’s what happens when you get what everybody asks for.
For simple maps that show a few examples of how to patch the SLAM!, check out Page
1) POWER CONNECTOR. First verify the POWER SWITCH on the front panel is off (out) and Outboard Power Supply is off (tog-
gle towards FUSE). The Outboard Power Supply has a captive 6 foot cable, with the mating plug. There is a painted white dot on the
plug that should face UP and/or gently rotate it to find the “key” or where it fits. Force is definately not needed. Rotate the ring on the
front of the connector CLOCKWISE about 1 turn, which locks the connector in place.
The SLAM! uses a trickle of power to remote control the power of the main supply. This means the Outboard Power Supply can not be
turned on without it being connected to the SLAM!. This is a safety feature. Also, with that exception and the +&-6 volt supply used for
tube filaments (heaters) all other pins are protected from passing current or a charge stored on power supply capacitors. In other words,
its pretty safe, and that you can’t get a shock, and can’t power it up hot but still better to have both power switches off to connect this plug.
2) CHANNEL 1 INPUT. This is a Neutrik Combo jack that accepts XLRs, 1/4” mono phone plugs, 1/4” balanced phone plugs. This
is both the LINE INPUT and the MIC INPUT. Phantom Power (6) is not advised except for some MICs, and in particular FET conden-
sor mics and some rare exceptions that require it. If Phantom is ON, turn it off before patching into this jack (or any other mic patch-
ing) or at least turn the monitors, headphones, etc down because there will be a loud speaker killing POP. Contrary to urban myth, it
is highly unlikely Phantom Power will damage any mic or cause it to sound different, except during patching. It is a good idea, not to
have Phantom on for LINE inputs, as it might be possible to damage something with the 48 volts if you select MIC (which can enable
phantom).
3) CHANNEL 1 OUTPUT. This is a transformer floating balanced +4 dBu output (Pin 2 hot). It is equally happy feeding balanced or
unbalanced inputs but for unbalanced inputs, be sure that the XLR’s Pin 3 is grounded or connected to Pin 1 or the shield. There is also
a transformerless unbalanced 1/4” phone jack output described below (5).
4) INSTRUMENT INPUT. This is a 1/4” mono unbalanced high Z input for guitars, basses, synths, etc. It has about 30 dB more gain
than the Combo jack input and uses the mic-pre. The input impedance is 100K suitable for synths and guitar processors/amp simula-
tors but might be a bit dull for some guitars direct. For very high Z (10 meg ohm) physically insert the jack half way. Cool trick, huh?
This will sound brighter for many guitars and basses, but should have little or no effect if any electronics are between the guitar and
input.
5) CHANNEL 1 UNBALANCED OUTPUT. This jack provides an unbalanced +4 dBu output pre-transformer. It can also provide a
semi-pro or consumer -10 dBv with plug inserted half way.

FAQ - Why no -10 input when you provide a -10 output? There is no dedicated -10 dBu input but both the Combo jack (2) and Instrument Input (3)
can be used in conjunction with the INPUT knob. Why share the same XLR for both MIC and LINE and no Phantom Switch on the front? It was origi-
nally, but we added the HP filter on that switch, and felt it was ‘safer’ for your speakers to have the phantom on the back (see item 17).
Why no separate MIC-PRE output? 3 reasons, the mic-pre would require a good line driver (no more space for more tubes), the opto limiter works
between both ‘sections’, and the Combo jack is used by both mic and line. In other words, it required 4 more XLRs and 2 tubes for this box and there is
no room. 2 channels & 24 jacks plus 6 switches already, and gotta draw the damn line somewhere.Why use bantam jacks for side-chain inserts? (see 8)
