CD SYM Section
Line level XLR input for sources with bal-
anced outputs (CD player)
The
INPUT MODE switch
CD SYM allows
to switch the CD XLR input between bal-
anced (XLR) and unbalanced mode.
10
PHONO Section
An additional line level input with the option
of XLR or RCA / CINCH inputs that you can
use to connect sources such as an external
phono preamplifier.
The
INPUT MODE switch
allows to switch
from balanced (XLR) to unbalanced (RCA /
CINCH) mode. Both of these inputs are
wired in parallel.
Please note that only one line level phono
input (either XLR or RCA / CINCH) can be
used at a time.
The PHONO inputs are not suitable for use
with a turntable without an external phono
preamplifier.
GND (GROUND)
Additional ground connection for external
units like phono preamp and so on
11
GROUND LIFT XLR-INPUTS
Ground lift switch for XLR inputs
Switch position:CONNECT TO GROUND:
Connects the XLR ground to chassis ground
(see Section 7.1 Troubleshooting: hum on
XLR input)
Switch position: DISCONNECT
Disconnects the XLR input ground from the
output ground
In true balanced operation, the ground con-
nection is not necessary, since it does not
carry a signal. Lifting the ground will help
keep out unwanted noise and interference in
balanced operation. If you have source
equipment fitted with a separate earth, you
should also use the DISCONNECT position
to avoid ground loop problems.
