Telex KP-5032, First Impressions

I am serving as the Truck-Compound Intercom Engineer (C2?). Primarily responsible for any deployed truck intercom resources, even if they are in the venue. The truck is MTV Networks “Atlas” which is almost completely OMNEO. Of the 432 ports, only 32 are analog. Because the 5032 can be run as Analog or IP (OMNEO or RVON depending on firmware), the assessment must include the complexities of the connection scheme.

1     The 5032 includes a front-panel AUX VOLUME control knob. The default is to adjust the MATRIX input level. This is intended to be a push-to-toggle between AUX1, AUX2 and the MATRIX signal in a mixing function. The problem is that the user can turn that knob all the way to “off” without any indication after the fact. The panel’s menu system does not allow this to be disabled. This has caused me several trouble calls. One idea is to make the knob toggle to an additional function to control SIDETONE. That should be the default? A continuous display of the current listen level would also be helpful.

2   The 5032 does not include a legacy D-SUB-9 connector for the analog frame connection. This is disappointing when integrating to legacy systems. Though, I do understand that legacy support can hamper the furtherance of a product. Just wish…

3  The ADVANCED AUDIO functions, particularly the compressor, is not powerful enough through the internal menu. Compression ratios of 1:1 (off), 2:1 and 3:1 are offered. I typically like to run the analog output of a Director’s panel through a limiter, like a DBX-160X. Ratios are closer to 8 or 10:1 to really protect the ears of everyone listening. As mentioned above, connectivity can impact the panel’s performance. If connected via an IP/Network topology, there is no way to access the audio signal to patch in an external limiter. The signal would have to be extracted and re-entered to the OMNEO stream as a gain-reduced version. Unless the available audio-process option was purchased for that particular key-panel, access to the audio settings are only accessed at the front panel, not through AZEdit. Not so easy if it is in front of a Director in a crowded TV truck.

As always, these points are hopefully the start of dialog. I appreciate counter points to correct my own myopic observations.

    Hey Comm dude. I like your blog. You mention running the Analog out put of a KP32 to a DBX and returning it to the intercom. How do you do this? I have tried taking the hot mic out to a DBX and return it into the MIC in with no results. I have read the manual and checked my station setting and they all seem correct. I tried running it into the AUX 2 input and in DSP function I have set AUX 2 to Matrix and not the MIC, but when I do this it kills my Hot MIC out. HELP??

    Much thanks from a simple audio human

      I try not to mess with the hot-mic or aux I/O or external mic. I let the KP do it’s normal thing and simply place the compressor/limiter in the path between the output of the key-panel and the input to the port/frame. If your system does not feature analog port-patching, you may need to interrupt the cabling to break-out the Talk, Listen and Data signals to gain access to the talk-signal.

      Alternatively, a separate mic-preamp/limiter can be placed in the path between the headset and the key-panel’s EXT MIC input, but remember to go in to the menu structure to select the EXT MIC. This is probably the best method if the key-panel is connected to the frame via IP or Omneo since the signal between the key-panel and frame is all data.
