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 ba4 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 unba4 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?
