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

unbalanced, using RCA type connectors.

The other two pairs of outputs are intended

for connection to a power amplifier. 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 "output

unbalanced. 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 left, looking from the

rear) and then connect your cables to the RCA

outputs ("main out 2"), audible hum will be

introduced.

You may use both 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 right). This will

avoid the introduction of hum.

PHASE SWITCH

On the right hand side of the top deck of the

chassis,

switch; phase is either normal or inverted one

hundred percent, depending on the switch

position. On initial connection, set the switch

to normal. Depending on the phase your

sources output and their facilities with regard

to phase, you may want to switch to inverted

phase sometimes. Phase issues generally will

result in lack of bass and/or focus of the stereo

image .

REMOTE CONTROL

The remote control provides the ability to

remotely:

Select the line source input

using either the numbered buttons or the

horizontal arrow buttons to each side of the

Mute button .

•

Control the volume level using the up

(louder) and down (quieter) arrow

buttons above and below the Mute

button.

•

Mute the volume using the button

labeled with a speaker cone with an "X"

across it, located between the "CH" and

"VOL" arrow buttons. Depressing the

mute button will run the volume

control down to zero. To raise the

volume again after muting, press the

mute button to take the volume level to

where it was prior to muting.

•

There is no power on/off on the

remote. The L-7000 on/off control is on

the face of the chassis only. This should

help prevent accidental powering off of

the L-7000 when the power amps are

still on.

INITIAL POWER-ON

Once you have your L-7000 in place and all

connections have been made to your sources

and amplifier(s) and the power cord is

installed and plugged into an AC receptacle,

you are ready to turn on the power for your

L-7000. Before you power up the L-7000,

though, be sure you have:

removed ALL the cushion materials from

inside the tube chimneysensured the

batteries are in the remote control – insert

the batteries by removing the bottom of the

remote control.

selected the output connections that you
