DO try to place the L-7000 away from major sources of RFI and EMI; though well
shielded, the L-7000 will function best away from large power transformers and other
sources of such interference.
B.
POWER CONNECTION
The L-7000 uses a standard three prong male 15 amp IEC connection for AC input. You need to
use a power cord with a female three prong 15 amp IEC connector at one end.
To the left of the IEC connector (facing the left side of the unit as in Figure 1), there is a power
on-off switch. Leave this switch in the OFF position – that means the switch is pressed "down" at
the bottom - while you make all initial connections.
The L-7000 will be set internally for your location's electrical system characteristics. Please check
the setting for electrical input on the label on the rear of the unit to confirm that your L-7000
matches your location's electrical system. For North American customers, the L-7000 is set
internally for AC 110/120 volt – 50/60 Hz. For customers in other regions, the unit is set for
230/240V – 50/60 Hz operation. There is no way to change to another AC setting.
C.
INPUTS
There are five (5) inputs. Line 1 and Line 2 are balanced connections (XLR type connectors). The
remaining 3 line inputs are RCA type, single-ended connections. None of the inputs is intended
especially for connection to any particular device.
NO PHONO STAGE - The L-7000 is a line-stage preamplifier and does NOT have a built in phono
preamplifier section. You will need a phono preamplifier if you want to use a turntable with the
L-7000. You can connect your phono preamplifier to any of the five inputs, provided you have
the appropriate types of connections or adaptors.
The L-7000 has been designed and manufactured to work most synergistically with Allnic Audio
phono preamplifiers, pre-preamplifiers, equalization and power amplification products, and ZL
Technology cables.
D.
OUTPUTS
The L-7000 has three pairs of outputs. Two (2) output pairs are balanced (i.e., separate ground),
using XLR connectors; one (1) pair is single-ended unbalanced, using RCA type connectors.
On the back panel of the L-7000 there is a switch to select either the balanced or single-ended
connections. This selection switch is at the top centre of the rear panel and labeled "unbalanced
output" (see Figure 2). Please set the output selection switch to the output connection you are
using. If you set the switch to "balanced" (i.e., XLR – switch pushed to the right, looking from the
rear) and then connect your cables to the RCA outputs ("main out 2"), audible hum will be
introduced.
You may use the balanced and single-ended RCA outputs at the same time; for example, if you
run one pair to your stereo amplifier and the other to a powered subwoofer (or a pair of them).
In such a case, set the output selection switch to unbalanced (RCA – switch pushed to the left).
This will avoid the introduction of hum.
