Connection

Connect outputs to each zone from the line level L+R RCA OUTPUTS on the rear panel (16) Up to 3 stereo line level inputs can be connected to the RX45 via the rear panel L+R RCA LINE INPUTs (17) (A further stereo 3.5mm AUX input is available on the front panel as a selectable source on the media player) Ensure the Power (1) is switched off until all input and output connections are in place.

The zones of the RX45 can be controlled directly from the front panel or can also be remotely controlled by
connecting up to five optional TR86 wall plates (ideal for local control from within each relevant zone).
TR86 wall plates are connected via RJ45 connectors (11) on the rear panel with CAT5/6/7 cable to each TR86.
The RX45 can provide power to each wall plate up to 100m away.

(adding external 24V power to the TR86 wall plate can extend this distance up to 1km) For remote announcement to all or any of the 5 zones, an optional CS-5 call station (953.049UK) can be added to the system. If a CS-5 call station is being used, connect this to the call station input (12) on the rear panel using network cable.

For announcements to all zones from the main RX45 unit, a paging microphone input is provided on the front or rear panel (2, 21).

If the paging microphone requires phantom power (e.g. condenser mic), enable this by selecting the phantom power DIP switch (20) to “ON”.

If DAB+ or FM radio is to be used, connect a DAB+/FM antenna to the rear panel ‘F’ socket (10) 24V MUTE CONTACTS (14) can be connected to the 24V trigger of an alarm system panel to mute playback.

If a line level siren or alert signal is available, this can be connected to the EMG AUDIO IN terminals (15).

When all other connections are made, connect the mains power to the IEC inlet (22) using the supplied lead.

The RX45 can operate standalone or as part of a larger zoned network using multiple RX45 units.
A standalone RX45 can serve up to 5 independent stereo output zones.

RX45 units can be cascaded in a ‘daisy-chain’ by connecting 2 CAT5/6/7 patch leads from the CASCADE OUT of the first unit to CASCADE IN of the next unit (19). It is important to connect the left-side CASCADE OUT to the left-side CASCADE IN and right-side CASCADE OUT to right-side CASCADE IN. Do not cross the patch cables as this will cause malfunction. The receiving RX45 can be linked onto further units by linking CASCADE OUT to IN in a similar fashion.

When RX45 units are cascaded together, the 3 stereo LINE INPUTS (18) are all linked together in parallel.

This is to allow all cascaded RX45 units to access the same audio sources. It is advisable to only connect line input sources to the first RX45 in the cascade to avoid any conflicting signals (for example, connecting an mp3 player to LINE INPUT 1 on the first RX45 and a CD player to INPUT 1 on the next RX45 will result in playback from both signals competing on the same channel)

In a cascade arrangement, the media player on the first RX45 in the chain can be assigned as an audio source for subsequent RX45 units using the MEDIA PLAYER DIP switches next to the “+24V Phantom switch” (20) as shown opposite.

Selecting the 3 leftmost DIP switches to “ON” (down) on the first (master) RX45 unit allows the signal from its media player to be fed onto the subsequent connected units.
(i.e. all DIP switches down except “+24V Phantom” unless phantom is used)

On the master RX45 unit, this setting makes its media player available to subsequent cascaded RX45 units.

Selecting the ‘MEDIA PLAYER – To Input’ switch to “on” on the subsequent cascaded RX45 units enables them to use this signal from the master RX45 media player and the leftmost 2 DIP switches determine which input channel it appears on: In1, In2, In3, or In4/USB)

(for example, if a cascade linked RX45 unit needs the master RX45 unit’s media player to appear on its LINE INPUT 3, switch down the ‘MEDIA PLAYER – To Input’ and the second DIP switch (CH-2) down.

On an RX45 unit that is cascaded, this setting makes the media player from the first unit appear on its LINE INPUT 3

If the master RX45’s media player is assigned to one of the line inputs of a cascade linked RX45 and another source is played through that line input, it will override the master RX45’s media player signal. It is important to keep track of which signal inputs are connected to or assigned to which channels.

Even when linked in cascade with other units, the MIC input (2, 21) only operates on the 5 zones of the individual RX45 unit. To page across cascaded units from a single microphone requires a call station.
For this purpose, 8 different group IDs can be set, providing up to 40 distinct zones (8 x 5 zones) using the group ID DIP switches (13)

Call Station

When using a CS-5 call station (instructions further on in this manual) to address up to 5 zones, the output will depend upon the group ID set on each RX45. The group ID is set via 3 DIP switches on the rear panel (13), labelled 4, 2 and 1 (the number is set in binary by adding up the 4’s, 2’s and 1’s, as shown opposite)

Paging any of the 5 zones from the CS-5 will only affect RX45 units with the same ID (for example, if three RX45 units are all set to ID 4 and zones 1 + 3 are paged on one of these units, the same zones 1 + 3 will be paged on the other two RX45s)

However, if TR86 remote wall plates (see below) are used with multiple RX45 units that are linked together in a cascade, each will only control the individual zones of the RX45 it is connected to and not affect any zones on other RX45 units.

Operation

When all connections are made, ensure that amplifiers or speakers connected to the zones are turned down.
Switch on POWER (1) to the RX45 and any further RX45 units that are linked in a cascade with it.
All channel LEDs will light, briefly showing the input sources (6), then change to VU meters for each zone.
Once the RX45 is powered up, turn up any connected amplifiers or speakers to a useful level for testing.
This can be increased later when the unit has already been checked.
Alternatively, the output of any selected zone can be checked through stereo headphones connected to the 3.5mm PHONES socket (8). Ensure the volume for this is turned down first, to avoid excessively loud output.

Ensure that the PAGE buttons are at the “out” position (3), which would otherwise override all other inputs.

Each channel has an illuminated button on the front panel and 5 LEDs above it.
Pressing the button for any of the 5 zones will cause it to illuminate and assign it for editing.

The 5 indicator LEDs will briefly show the input source (1, 2, 3, 4/USB or LOCAL), then revert to acting as a VU level meter for that zone.

To select an audio source for a zone, press the zone select button to step through the input sources 1, 2, 3, 4/USB. Note: The input level of line inputs 1, 2, 3 can be adjusted on the rear panel with 3 miniature trim controls, which is useful for loud input sources.

Input 4/USB is for the internal media player. LOCAL is a line input wired into a TR86 wall plate (if this is used).

When a zone is selected, it can be edited in the master section on the right- side of the zone selectors. Pressing the ∧  button repeatedly will increase the output level on that zone and pressing ∨ repeatedly will reduce the output level on that zone. This is indicated by the 6 LEDs in the master section.

EQ button has 2 functions. A brief press will mute the output of the selected zone.

Hold this button for 3 seconds and the master section will enter the EQ mode.
The HF LED will light, enabling ‘treble’ adjustment using the ∧ and ∨ buttons.
Pressing EQ again will cause the LF LED to light and enable adjustment of ‘bass’ frequencies in the same way, using the ∧ and ∨ buttons.

Pressing EQ again continually toggles between HF and LF, allowing repeated adjustments of treble and bass.
Press and hold the EQ button for 3 seconds to exit the EQ menu.

TR86 Remote Wall Plate

Each zone of the RX45 can be remotely controlled by a TR86 wall plate connected to the RJ45 sockets on the rear panel (11). TR86 wall plates are available to purchase separately (953.050UK) and are only needed for remotely controlled zones.

The TR86 is touch operated with a toughened clear acrylic surface, which is neat and hygienic, and is designed to fit into a standard single gang 86 x 86mm back box (35mm minimum depth)

23 Local DC power input (24Vdc)
24 Local audio input (unbalanced line)
25 RJ45 remote connection
26 Source select pads
27 BUSY indicator
28 Volume up/down pads
29 Audio source indicators
30 LOCAL audio override
31 MUTE audio

Connect each TR86 via a network cable with RJ45 connection (25), which will require a gap to access from the rear of the back box. This will deliver power to the TR86 for up to 100m. For longer cable runs up to 1km, the TR86 will require separate local 24Vdc power supplied to the screw contacts at the rear (23)

Tapping the ∧ and ∨ ‘CH’ select pads (26) will step the audio source for the zone through 1, 2, 3 and 4/USB.
(where 4/USB is the RX45 internal media player)
The active audio source is indicated by LEDs at the side of the CH select pads (29)

Tapping the LOCAL pad (30) enables the TR86 to provide an audio source for its own zone.
This is an optional mono line level signal (0.775Vrms @ 0dB) connected via terminals on the rear panel (24).
Note that this shares the GROUND connection with the 24Vdc power input.
The local input source is line level and can be wired to a wall plate with an audio connector for AUX in.

Tapping the + and – pads (28) will increase or decrease the output volume of the zone in increments.

The HF (High Frequency or Treble) and LF (Low Frequency or Bass) EQ for a zone can only be edited from the from the onboard controls on the RX45. This feature is not available to adjust from the TR86 wall plate.

Tapping MUTE (31) will mute the output of any playback to the zone, although paging will still be available.

When the zone is paged from the RX45 MIC input or a call station, the BUSY LED will light (27).
When this LED is lit, playback sources will be muted until paging is deactivated on the MIC or call station.
The same applies if the RX45 receives an emergency 24V trigger on the 24V MUTE contacts.

Note: Changes on the TR86 will be mimicked by the zone LEDs on the main RX45 unit. However, the TR86 does not continually follow manual changes on the front panel of the RX45, but the indicators can re-sync when the channel is operated from the TR86 again.

System checking

To check outputs without powering up speakers, connect a set of stereo headphones to the PHONES output jack (8). Turn down the PHONES to a low level firstly for hearing safety and increase later if necessary.
Speakers may be powered up for this instead, but it is advised to keep to lower levels for initial checking.

If a paging microphone is connected (2, 21), this can be used to check that there is output to all channels.
Turn the paging microphone level down (4). Many paging microphones have their own paging button, which should be left switched on. Push in the PAGE button (3) and speak into the paging microphone, whilst gradually increasing the paging mic level as required. Check each zone in turn by pressing its select button (6)

To check individual outputs to each zone in turn, make sure the PAGE button is at the “out” position and the MIC LED (5) is not lit. Whilst a signal is playing into one of the line inputs (18), press the zone selector button for each zone until that source is selected and ensure its volume is up part way for checking.
If no sound is heard, check the level control for that line input is not turned fully down (17).

If there is no line input source available, the internal RX45 media player can be used for checking. Set the zones to “4/USB” and see the section below for operation of the media player.

If a CS-5 call station is connected to the RX45 (see below), it can address all or any of the 5 output zones from the keypad. Press the required zone button(s) followed by the large green talk button and speak into the CS-5 microphone.

Media player

The RM120D mixer-amp is fitted with a built-in media player (1) The media player has a Bluetooth receiver, USB/SD audio player and a DAB+ or FM radio tuner. Pressing the SOURCE select button will step through Bluetooth, SD, USB, DAB and FM tuner modes. Pressing the MUTE button for any source will mute the output. Holding the MUTE button powers down the media player and pressing it again powers it up again.

Settings menu

The media player has a menu for global settings, which can be accessed by holding down the SOURCE button.
