Low output on monitors from console ?

We just purchased a pair of Yamaha HM 50 Monitors for our RS Millenium console.

The input going into the speakers is very low. Would a audio preamp solve the issue.

Thanks.
 
HM50, or HS50M
 
The Millenium may or may not have it, but make sure none of your modules are dimming the monitors for cue purposes. I know one engineer who was unaware of that feature in a console and he ripped things apart to only discover this "feature" was something he thought he defeated during installation.
 
Thanks Bill, I am using J15. I think The dimming outputs are actually on different plugs ?

This is what the manual says:

"Three stereo, balanced, high level (lv RMS typical) are provided. Each output will drive loads of 2K ohms or greater.
The outputs are Dimmed
Monitor (controlled by Mute 1), Muted Monitor (controlled by Mute 2), and Unmuted Monitor. All outputs follow the monitor
selection switches but only the Dimmed Monitor is affected by the front panel monitor level control.
Connectors are located on the Output Board as follows.
Output Board Header Monitor Output
J12 Dimmed Monitor (Mute 1)
J15 Muted Monitor (Mute 2)
J16 Unmuted Monitor"

All monitor outputs are intended to drive external monitor amplifiers. The Dimmed Output, controlled by Mute 1, (which
also mutes the Cue speaker) is intended to feed the control room monitor amplifier where the console is located. When
the Mute 1 bus is enabled, the output from the Dimmed Output will be reduced to a level set by VR13 located on the
Output Board. This level may be set to maximize (for full muting) or, alternatively, to a level just below the feedback
threshold of the speakers.
The Muted Output is intended to feed any other room which that contains microphones connected to the console.
If it is desirable to feed all studios from a common amplifier, this amplifier should be fed from the Unmuted Monitor Output.
External relays driven by the muting contacts on header J7 could then be used to provide the necessary muting of
the signal.
 
Of course if you're really in a pickle just give Radio Systems a call. I had a tour of their facility a couple of years ago and I was impressed to see American manufacturing still employing local workers to produce some quality products. Their tech folks are sharp and I would be happy to use their consoles in a heartbeat. If there's a problem I'd bet they'd be able to suss it out over the phone with you.

They would be my first choice to replace the 37+ year old Gates console I have in my school station's master control but I have to live with what budget we don't have.
