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 (toggle
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 (17) is not advised except for some MICs, and in particular FET condensor
mics and some rare exceptions that require it. If Phantom is ON, turn it off before patching into this jack (or any other mic patching) 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 (6).
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 simulators 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) DAC OUTPUT. (Left) This is a direct balanced +4 dBu output of the DAC if that option is installed. We calibrate the output so that
Digital Full Scale = 8.0 volts and that Digital -14 = +4 dBu. Other calibration or reference levels requires a simple internal trimmer tweak.
6) 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. Most other Manley gear makes this unbalanced output jack entirely bypass the
transformer and thus disables the balanced XLR output. There is an internal jumper to provide this mode, if needed (see page XX). In the
SLAM!, the transformer is also used to drive the A to D converter, which we did not want to 'mysteriously lose' when they plugged into
the 1/4" output. With the jumper in the alternate position (expert mode), this 1/4" jack can be used as the main output to feed an EQ, and
returned to the male 'output' XLR which will feed the A to D directly and passively. We like 'expert mode' but can't ship it that 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 originally, but
we added the HP filter & DAC 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 (26) plus 6 switches already, and gotta draw the damn line somewhere.Why use bantam jacks for side-chain inserts? (see 18)
