B GROUND TERMINALS Different studios have different grounding practices. This unit
allows the user access to chassis and circuit grounds on mini binding posts. Typically the
circuit ground is connected to the chassis ground with the included "strap" and ground is via
the AC third pin. Some studios prefer to run a separate ground wire to each piece of gear and
the separate terminals will help. Chassis ground will often be via the rack rails. The text books
say that there should be one and only one connection to ground for each piece of equipment.
This can be the third pin AC ground (most legal and safe) or the rack rails, or the audio
shields, or a dedicated ground wire. Many studios cut every shield from either all sends or all
returns except mic lines. This unit is transformer isolated at all inputs and outputs so it will be
most "forgiving" of ground problems. Internally, the differential circuit topology cancels
supply hum too.
C LINE OUTPUT (XLR) . TRANSFORMER ISOLATED AND BALANCED. Pin 1 = chassis
ground, Pin 2 = hot or + on all XLRs, Pin 3 = low. To feed unbalanced gear you can connect
pin 1 to pin 3 if needed.
D LINE IN (XLR). TRANSFORMER ISOLATED AND BALANCED. Input impedance is
1000 ohms which may be a difficult load for some semi-pro gear. Most pro equipment can
easily drive 600 ohms (even more difficult) as is found in a lot of vintage gear.
E MIC PRE OUT (XLR). TRANSFORMER ISOLATED AND BALANCED. This can be
used to feed a tape machine directly or to feed a compressor.
F MIC PRE IN (XLR). TRANSFORMER ISOLATED AND BALANCED. Input impedance
is 2400 ohms which seems to be the standard and matches well with low imedance mics (150
ohms). Phantom is 48 volts.
G IEC MAINS CONNECTOR. Used with AC cable correctly wired for your countries
voltage. Different Mains AC Voltages require internal re-wiring or transformer replacement
that should be done by the dealer or Manley Labs.
