JBL P941, P81 manual Making Connections, To Make Connections

MAKING CONNECTIONS

The P81 and P941 feature gold-plated binding posts that allow for two meth- ods of connecting the speaker wires.

CAUTION: Never make or break con- nections unless all system components are powered off.

Before making connections, note the following:

Insert Banana Plug here if desired

5.Repeat Steps 1 to 4 to connect the second P81 or P941 to a separate amplifier/receiver output channel.

An alternative connection method, instead of those described in Steps 1 to 3, is to attach standard banana plugs to the speaker wires and plug them into the ends of the speaker connectors.

The hole in the center of each collar is

•Make all connections observing the proper polarity, positive-to-positive (+) and negative-to-negative (–). Connec- tions that do not observe the proper polarity will cause poor stereo imag- ing and diminished bass response. With the advent of multichannel sur- round systems, maintaining proper polarity remains equally important to preserve the correct ambience and directionality of the program material.

•Use high-quality loudspeaker cable with a maximum total loop resistance of 0.07 ohms or less (for each wire run). Refer to the table below to determine the appropriate maximum wire gauge.

•All in-wall speaker wires must be UL listed for use in in-wall applications.

CAUTION: Be sure to comply with local wiring codes. JBL is not responsible for any damage or injuries that may result from faulty wiring.

Maximum Wire Gauge
Gauge	Length	Length
(AWG)	(Feet)	(Meters)
6	87	27
7	69	21
8	58	18
9	43	13
10	34	10
11	27	8
12	22	7
13	17	5
14	14	4
15	11	3
16	9	3
17	7	2
18	5	2

NOTE: High loop resistances that exceed 0.07 ohms (for each wire run) will cause the filter network to mis- terminate, resulting in considerable degradation of sound quality.

•Contact an authorized JBL dealer for information about the suitability of power amplifier/receiver components before connecting the P81 or P941 to the associated power amplifier/ receiver.

•Review the owner’s manuals for asso- ciated audio components to deter- mine their connection procedures.

Connections are made between one pair of P81 or P941 input connectors and one amplifier/receiver output channel, as described below.

To Make Connections:

1.Loosen the terminal connectors by hand (counterclockwise) on the speakers’ positive (+) and negative

(–) binding posts until the holes in their threaded posts are visible.

2.Insert the stripped ends of the wires through the holes, as shown in Figure 18.

3.Retighten the connectors by hand (clockwise) to secure the wire. Be sure no stray strands of wire from one binding post touch the other binding post, as this will short-out the signal and may damage the amplifier.

4.In the manner described above, con- nect one pair of loudspeaker wires to the P81 or P941 input connectors. Then connect the same pair of loud- speaker wires to the desired amplifier/ receiver output channel.

intended for use with banana-type con- nectors. To comply with European CE certification, these holes are blocked with plastic inserts at the point of manufacture. The use of banana-type connectors requires the removal of the inserts. Do not remove these inserts if you are using the product

in an area covered by the European CE certification.

If using a back box or if limited by installation depth, the banana plugs can also be inserted through the sides of the binding posts. See Figure 18.
