Installation, cont’d

C	Audio input captive screw connector (MTP T SV A,
	MTP T AV) — Connect a balanced or unbalanced audio input
	to this 3.5 mm, 5-pole captive screw connector. Connectors are
	included with each MTP. See Figure 1-2 to wire a connector
	for the appropriate input type. Use the supplied tie-wrap to
	strap the audio cable to the extended tail of the connector. High
	impedance is generally over 800 ohms.

CThe length of exposed wires is critical. Ideal length is 3/16” (5 mm). If the stripped section of wire is longer than 3/16”, the exposed wires may touch, causing a short circuit. If the stripped section of wire is shorter, wires can easily be pulled out even if tightly fastened by the captive screws.

NWhen making connections from existing audio cables see Figure 1-3. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring,

	and sleeve.
