The back panel of the Z40i+ features the IEC connector, power
switch, tape in, tape out, four pairs of RCA inputs, one pair of XLR
inputs, one pair of RCA subwoofer outputs, and four binding posts.
Inputs
There are five total inputs: four RCA stereo pairs and one stereo
XLR pair. The XLR input provides a tube-coupled balanced input.
The preampfification stage converts the balanced input into a
single-ended signal that suffers no voltage loss. The Z40+ also
features the possibility of adding an optional MM/MC phono
preamplifier. For more information regarding the operation of the
phono preamp, please refer to our website or the additional
Phono User Guide included with your Z40i+.
Outputs
The speaker outputs use binding posts that allow you to use
banana plugs, spades, or bare wire.
There are two headphone outputs: one “HI” and one “LO”. These
refer to the output power, not the impedance. Use the HI output
for full-sized headphones that need more power and the LO
output for more sensitive headphones. Each uses a 1/4” jack.
There is a switch to use either the headphone outputs or the
speaker outputs. Always lower the volume before switching
between the two.
The Z40i+ also features an additional preamp-level SUB OUT which
is step-attenuated. This is a unity gain op-amp coupled, stereo
RCA preamplifier output meant to be used with low-pass filtered,
active subwoofer RCA inputs. The Sub Out is menu configurable for
Stereo, Mono or Mute. The Sub Out is automatically switched off
when the output switch is set for headphone operation.
Tape Monitor
When Tape Monitor is selected via the button on the front panel,
the selected input sends an unattenuated signal directly to the
Tape Output and the Z40i+ outputs the signal from the Tape Input.
