Connection

Ensure the Power (11) is switched off until all input and output connections are in place.
Turn all output rotary level controls (9) fully down (anti-clockwise) to avoid loud noises when switching on.
Set the BASS and TREBLE Tone controls (1, 2, 4, 5) to the vertical position (zero)

Loudspeakers should be connected to the RMS605 via screw terminals on one of 2 removable modular connectors.
If the speaker(s) being connected is not 100V type, use the terminal block marked “4Ω” for this channel (14).
Connect + and – wires to each speaker as indicated, ensuring that there is no chance of strands shorting across terminals.

Important: Ensure that the load is no lower than 4Ω for each output. This can be…

1 x 4Ω speaker
1 x 8Ω speakers
2 x 8Ω speakers wired in parallel (4Ω)| 1 x 16Ω speaker
2 x 16Ω speakers wired in parallel (8Ω)
3 x 16Ω speakers wired in parallel (5.3Ω)
4 x 16Ω speakers wired in parallel (4Ω)
---|---

Ensure that the connected speakers can handle 60W from each output.

If the speaker(s) being connected to an output channel are 100V type, use the terminal block marked “100V” for this output channel.
When connecting multiple 100V speakers to this output, connect all speakers in parallel and ensure that the total load is below 54W. The wattage of each speaker can sometimes be adjusted via tappings on the speaker (check the speaker’s documentation if unsure)

DO NOT connect to both 4Ω and 100V terminals for any individual output channel
DO NOT mix 4Ω and 100V speakers on any single output.

THERE SHOULD BE NO CONNECTION MADE VERTICALLY ABOVE OR BELOW ANY OTHER

The RMS605 has 5 independent speaker output channels and can be used as a 5-way slave amplifier.
Set each AUX/CH switch (6) to the ‘out’ position (for individual channel input)
If connecting input to a channel via the pair of RCA inputs (15), these will be summed to mono.
If connecting input to a channel via Euroblock terminals (20), the green block may be removed from the panel for ease of handling.
Connect the signal “+” connection to the “+” screw terminal and the “-” connection to the “-” screw terminal.
If there is a separate “ground” connection (i.e. balanced cable), connect this to the “G” terminal.
Otherwise, for unbalanced connections, connect to “+” and “G” (or link both “-” and “G” connections with a piece of wire)
If 2 or more channels will share the same audio source, there is an option to connect this to the AUX input (16)
To route the AUX to any of the output channels, press the AUX/CH switch to the ‘in’ position for each channel to receive the AUX input.
For convenience, the AUX/CH switch can be switched in our out whenever AUX or individual channel input is needed.
For announcements and alerts, there is a PAGING MIC XLR input on the rear panel (18)
Connect a microphone to this input if required and select the PHANTOM power DIP switch (21) to “on” if it is a condenser microphone that requires external phantom power from the XLR connector. Next to the PHANTOM power DIP switch is the VOX DIP switch for voice override. Switching this to the “on” position will cause all other inputs to be muted when a sound is detected through the paging microphone input. The amount by which this muting takes effect is adjusted using the “VOX” rotary trim control (17)

The PAGING MICROPHONE input is always live to all output channels and the GAIN (8) or signal level control and BASS + TREBLE tone controls (1, 2) for this input are located on the front panel. If the microphone is too quiet, increase the GAIN control or if it is too loud, turn this control down. Adjust the BASS and TREBLE controls to achieve the required tonal balance for the microphone output.
If available, connect a 24V trigger from an alarm panel to the alarm contacts (17) to mute all except channel 1 in an emergency.
Connect the rear IEC inlet (16) to the mains using the supplied mains lead (or an equivalent approved type).
Ensure that the supply voltage is correct for this equipment and that the main outlet is switched on.

Operation

When all signal and speaker connections are made, power up the RMS605 and gradually increase the LEVEL control of each channel to check the output to the 5 zones. Adjust the levels to the required amount and use the BASS and TREBLE controls to adjust the tone as necessary. For each, the 12 o’clock position is zero, and rotating left decreases the amount of bass or treble whilst rotating right increases the amount of bass or treble.
Test the PAGING MIC input by gradually adjusting the GAIN control to the level needed to hear the microphone clearly through all channels. Again, adjust BASS and TREBLE controls to ensure that the paging mic output is clear and intelligible. If the VOX function is being used, adjust the VOX control on the rear panel to the sensitivity required to hear announcements over background music.
If needed, test the emergency mute contacts (19) by applying 24V across the terminals as indicated – all inputs except for the paging microphone should be muted.
After use, turn down all LEVEL controls before powering down to avoid loud pops or clicks through the connected speakers.
