System Setup
System setup and operation is quite simple. For the portables, simply install two 9-volt
batteries, plug in the headset, and turn the unit “on.” Install the batteries from the bottom of
the remote. Unscrew the captive screw on the battery-compartment cover to get to the
batteries. Install the two batteries with the positive (smaller) terminal toward the center of the
QTR-2/QTR-600 and oriented toward the shiny metal battery contacts. Ensure that battery
removal straps are positioned correctly alongside the batteries so they may be easily removed
when discharged. Replace the battery cover, making sure that removal tabs are folded over
the top of the batteries, out of the way of the cover.
NOTE: The battery compartment is keyed to resist incorrect insertion of the batteries. If the
batteries do not fit easily into the compartment, do not force them. Check the orientation of
the battery terminals and correct any misalignment, then reattempt insertion.
To set up the master station and balance the system, proceed as follows (refer to Figure 2 for
the location of DIP switches and controls):
1) The master station is equipped with removable rack-mounting ears and may be used
either as a desktop unit or in a rack. If it is to be rack-mounted, install the accessory
ears onto the chassis; otherwise, install the four plastic feet provided with the unit on
the chassis bottom.
2) Ensure the intercom interface is properly programmed for the type of intercom to be
used. If necessary, remove the two screws on the rear of the dust cover and slide off
the cover to get to the programming DIP switches. Use Table 1 to determine the DIP-
switch settings necessary.
3) If the master station is to be operated from 230 V
ac
, remove the dust cover and set the
voltage-selector switch on the front of the power supply PCB (SW4) to “230.” Replace
the dust cover and install a 1/4-A fuse in place of the 1/2-A, 115-V
ac
fuse.
4) If the master station is to be rack-mounted, external antennas likely will be needed. For
desktop use, the whips supplied will be satisfactory.
5) Mount the master station and connect the antennas. Also connect power (ac or dc or
both) to the unit.
6) Plug in intercom cable(s) to the rear panel. For Clear-Com “TW” and RTS operation,
the second XLR connector may be used for loop-through to the next station. For a
standard Clear-Com system, the second connector is for a second audio channel. Select
the desired I/C channel on the master station “CH SEL” switch.
7) If the link is not used, disable the circuits with the link on/off switch (rear panel). If
the link is to be used, connect the master station to the external audio equipment
(console, etc.) or to a second (slave) master station with standard two-conductor
shielded mic cables.
8) Select the transmitter mode with the “TRANSMIT” switch (rear panel). The “ON”
(continuous) mode is normally used, but the “PTT” mode should be used if the master
station will be left powered when the system is not in use. This mode automatically
shuts down the QX-6A/QX-600 transmitter when no portables are transmitting
9) Power “up” the master station and all portables to be used. Enable the active portables
via the “ENABLE” push buttons on the QX-6A/QX-600 front panel; unused channels
should be disabled to avoid possible interference. Also, enable the wired intercom. At
this point, the front-panel LEDs for all selected portables, the power LED, the TX
LED, and the I/C LED should all be “on” (assuming an RTS or Clear-Com wired
system).
10) Plug a headset into the master station front panel and select the “LOC” mode (push
button “in”). This will allow two-way communications with the portables and the
wired intercom during setup.
11) Adjust the audio levels from each portable via the “CH ADJ” (front panel)controls on
the QX-6A/QX-600 while each user is speaking. Also adjust the local headset mic
level to be approximately equal to that from the portables.
