Connection Precautions
Disconnect the AC cord before and while making or changing any input, trigger, or speaker
connections. Make sure there is no strain or tension on any connections that could cause
them to pull loose.
Antenna Connections
The Ztuner cannot receive any FM or AM stations without separate antennas for each band.
Adequate reception and sound quality depend on antennas suitable for your location.
FM Indoor Wire Antenna
A standard FM “folded dipole” T-shaped flexible wire antenna is included with your Ztuner.
It should be adequate for most urban and suburban locations where there aren’t surrounding
tall buildings and/or hills.
Connect the 300
Ω
(ohms) antenna wire’s two spade connectors to the screw terminals on the
small 300
Ω
to 75
Ω
balun adapter. First loosen each screw and insert a spade lug under each
of the lock washers. Tighten the screws to hold the wires securely.
Push the balun’s plug carefully onto the round antenna receptacle marked FM 75
Ω
.
You should be prepared to adjust the position of the wire
antenna to optimize reception. Clear reception of certain
stations may require a different antenna orientation, espe-
cially if there are tall buildings and/or hills nearby.
Outdoor Antenna
For best reception with the least background noise, we
recommend the use of a high-quality outdoor FM antenna.
Use round 75
Ω
coaxial cable from the antenna with an “F”
connector (not included) which you plug into the Ztuner’s 75
Ω
FM antenna receptacle. If you use
flat 300
Ω
twin lead antenna wire, use the balun adapter as described above.
Cable Transmission
Most cable companies transmit FM stations as well as TV. Check with your local cable company
about the availability of FM stations. The quality of FM radio varies widely among cable operators.
Your Ztuner connects the same way as a second television: Use a TV-FM signal splitter (not includ-
ed) with the incoming cable connection and connect one wire from the output of the splitter to
connect your television and the wire from the other output to the Ztuner FM connector.
Powered FM Antennas
A small powered indoor antenna is sometimes useful when it’s impractical to install an outdoor
roof-top antenna or where FM transmission is not available via cable or a community TV/FM
antenna. However, powered antennas can occasionally add noise and distortion. In many cases,
you will receive clearer signals with the supplied dipole wire antenna.
AM Antenna
A single wire is supplied as an AM antenna. Connect it to the AM antenna terminal and position
it for best AM reception.
Audio Out Jacks
Connect standard audio cables from the L and R Out jacks to the Tuner input on your preamplifi-
er or system controller. You may connect the Ztuner to any line-level input, even if the input isn’t
labeled “tuner.”
