TV ModMinder is the precise, economical way to monitor the parameters of your stereo signal. It provides continuous status of key multichannel television sound characteristics, including total modulation percentage plus over-modulation; peak flasher, status and injection levels of subcarriers.
ModMinder represents an improvement in accuracy over traditional TV modulation monitors. And because it works with a wideband aural capable precision demodulator, (such as the MSI 320) it's more economical as well.
Autoranging display shows total modulation percentage in the current operating mode (for any combination of subcarriers) on a large, easy-to-read meter. A large, bright, highly accurate peak flasher with specially driven long-life incandescent lamps is an improvement over traditional LEDs. ModMinder also has illuminated, push-button display of stereo pilot, SAP and PRO channel subcarriers.
Bridging input allows ModMinder to be driven from a stereo generator, composite STL or any source of BTSC composite. And TV ModMinder is easy to set up and operate.
- Economical MTS Monitoring
Because it works with your wideband precision demodulator, the TV ModMinder is far more accurate and far less expensive than traditional modulation monitors. The TV ModMinder does for routine operation what the Modulation Sciences SRD-1 Stereo Reference Decoder does for setup, testing, and maintenance of MTS audio.
Total modulation percentage in the current operating mode is read precisely on a large, easy-to-read meter. In BTSC stereo, the deviation that equals 100% modulation changes, depending on which subcarriers are in use.
TV ModMinder autoranges to the correct deviation for any combination of subcarriers and displays the value in kHz that equals 100% modulation on a two-digit readout.
- At-A-Glance Status Monitoring
The highly accurate peak flasher indicator is large and bright. TV ModMinder's specially driven long-life incandescent lamps are far more noticeable than LEDs. The status of the three subcarriers Stereo Pilot, SAP, and PRO is shown by a row of illuminated push buttons.
Press any of the lighted buttons and the meter displays the injection level for that subcarrier.
A wideband demodulator will most often drive TV ModMinder. However, it can also accommodate any other source of BTSC composite. Input impedance is bridging.
TV ModMinder can be driven from the output of any stereo generator or it may bridge the output of a composite STL.
