The SIEM250 is an easy to setup and great sounding all inclusive Wireless in ear monitoring solution from Smart Acoustic. With each SIEM250 you get 1 x Transmitter, 1 x SRC250 Bodypack, an Earphone set with replacement grommets, 1 x Antenna and Power Adaptor all contained within a road worthy metal travel case. Running on the UC UHF band with a frequency range of 655 – 679MHz, linking your Transmitter and SRC250 Receiver together is a quick process. Simply match the Channel number on both units and you are good to go. You can create either Mono or Stereo in ear mixes on your mixing console to send to your SIEM250 systems XLR inputs. The LCD display on the Transmitter will then show you the level of signal entering the unit so you can adjust the Input Level control on the face of the SIEM250. If signal needs to be reduced further, there is a handy -12dB pad switch on the rear of the Transmitter. You can also monitor the signal being sent to a body pack with the SIEM250’s headphone output. The lightweight and durable poly carbonate SRC250 Bodypack Receiver that comes with your SIEM250 system can be mounted to your belt or to a guitar strap. It is powered by 2 x AA batteries and has >5 hours operating time. On the easy to read LCD display of an SRC250 you can monitor in real time the RF connection strength to the Transmitter and the level of signal being sent to the SRC250. You can also monitor the Battery life in the unit and can quickly adjust your output level with its volume control. The SRC250 also allows you to set discrete EQ specifically for that receiver with 2 different modes. Extra SRC250’s can even be added to a SIEM250 system to receive the same mix signal. The SIEM250 Transmitter can be rack mounted in a 1RU space with the included Rack Ears.
