3. Strip 1/2" of insulation from the speaker cable.

4. Gently slide the (5/8") bare end of the 14-gauge wire into the

center of the bare speaker cable (be careful not to spread the

individual wires of the speaker cable).

5. Solder this connection. A high-wattage soldering gun may be

necessary to provide adequate heat.

6. Lightly "tin" the remaining (1/2") bare end of the 14-gauge wire.

7. Gently slide a 1" length of shrink tubing over the connection and

heat to shrink. (Color-coded shrink tubing is available for polarity

identification.)

8. Follow this procedure for the remaining speaker connections.

Depending upon the type of speaker terminal, this procedure may

also be used for the speaker end of the cable.

When the speaker cables are complete, connect the left-channel +

(positive or red) output post of the Nº29 to the + (positive or red) input

terminal of the appropriate loudspeaker.

Connect the left-channel – (negative or black) output post of the Nº29

to the – (negative or black) input terminal of the appropriate

loudspeaker.

Repeat this procedure for the right channel.

Note: The Nº29 provides two sets of output posts to

accomodate the increasing number of loudspeakers that call

for bi-wiring. For specific instructions on bi-wiring, refer to your

loudspeaker owner's manual or see your Mark Levinson dealer.

For the best sonic peformance, we recommend against using

the two sets of output posts to connect two sets of full-range

loudspeakers. Doing so, however, won't damage the Nº29, as

long as the total load impedance is at least 2Ω.
