Studio Technologies Model 41 Interface with 4 Independent IFB Circuits

The Studio Technologies Model 41 is a top - notch interface crafted to generate broadcast - standard IFB outputs from line - level audio sources. Its main job is to connect the analog outputs of digital matrix intercom systems with broadcast IFB user devices. This model creates four separate IFB outputs. Each output supplies DC power and two analog audio signals to support the connected devices. The audio quality is outstanding, with minimal hiss, hum, or other unwanted noise. The unit also offers resources for both visual and audible monitoring of audio output signals. Plus, it monitors the DC output voltage for any faults. Key features include transformer - coupled inputs, excellent audio quality, superior power - feed performance, four independent IFB circuits, single rack - space mounting, and universal mains input powering. In terms of technical specs, it has well - defined frequency responses, low distortion, high S/N ratio, specific audio input and output characteristics, and clear connector details.

Using the Studio Technologies Model 41 is quite straightforward. First, connect your line - level audio sources to the 25 - pin female D - subminiature audio inputs. Then, link your broadcast IFB user devices to the 3 - pin male XLR IFB outputs. If you want to monitor the audio, plug your headphones (with impedance of 100 ohms or greater) into the 1/4 - inch 3 - conductor phone jack. For power, connect the unit to an AC mains with 100 - 240 V (±10%), 50/60 Hz. Make sure the voltage is within the specified range to avoid any damage. As for maintenance, keep the unit in a clean and dry environment. Check the connectors regularly for any signs of wear or damage. If you notice the status LEDs on the monitor section flashing, it means the DC voltage on pin 2 of the IFB output connectors is less than approximately 24 Vdc. In such a case, you should check the power supply and connections.
