Connections
Inputs - Source 1
Any balanced source component may be connected to source 1. Best results will be generally obtained
when the source component offers a moderate to low output impedance as most (but not all) balanced
source components do. If your source component offers both balanced and unbalanced outputs, it may
be worthwhile to undertake a listening test to determine which one sounds best.
Inputs - Source 2 thru 4
Source 2 thru 4 are supported by RCA type single ended inputs. These three sets are all electrically
identical, offer a 50K ohm input impedance coupled with a very low input capacitance thus making them
suitable for use with a wide range of source components.
If your source components have a variable or selectable output level, we suggest that you try between
some of these settings and the fixed (or maximum) output level to see which one delivers the best
sound quality and ease of use for your system.
Outputs
Two pairs of RCA’s and one pair XLR’s are used for output connection. When the Balanced / SE switch
is set to SE, all three outputs function. The XLR’s in this case output a single ended signal with pin 2
being signal and pin 3 becomes grounded.
When the Balanced / SE switch is placed in the Balanced setting, all three outputs function. The XLR
sockets provide a full true balanced signal and the RCA’s operate normally but with a reduced gain and
output impedance.
It is possible to use any combination of output sockets simultaneously if required.
Output impedance
In SE mode the output impedance at all three pairs of outputs is 75 ohms.
In the balanced mode output impedances are 37 ohms per phase on the XLR with pin 2 being “Hot” and
pin 3 being “Cold” while being 37 ohms on the RCA outputs.
The K-10 is capable of output levels in excess of 20V RMS and is comfortable with loads as low as 1K
ohm.
A Note on the RCA sockets
Great care should be taken, especially with cables that fit too tight or use of locking systems that might
not be in sufficiently released before removing the cable from the pre-amplifier. Any un-due twisting of
the RCA sockets may cause them to loosen and possibly damage the fragile wires connected to them
on the inside of the pre-amplifier.
