ACE turbocharged the “PLAY2FM” studio, a well-known online media specially invited for the 11th Jazz Festival which just ended in late October 2015.

In the festival, the studio broadcasted live online and organized small performances. In a two-day schedule, they interviewed with the participating guests, organized DJ mixing performances and made interaction with the audience.

It was a typical EFP mobile box-mounted radio studio. The equipment was required to be easy to carry and the system easy to built and use without affecting broadcasting safety and stability. The host and guests were allowed to move freely for better interaction with the audience. The equipment may be conveniently controlled remotely by the sound engineer. In addition, they system was required to have the ability for sound reinforcement and monitoring of the broadcast signals.

Given these needs, we recommended the use of the Soundcraft Si Performer1-BC digital mixer (with double bridge and IPad remote expansion interface), Shure ULXD™ digital wireless system and Shure PSM300 digital personal wireless listening system.

Soundcraft Si Performer 1-BC Digital Mixer

The studio used the Soundcraft Si Performer 1-BC digital mixer. It is easy to install due to its integrated design. It can be simply embedded in the workbench to facilitate use by DJ and is also portable. It has powerful functions with its 16 physical faders of the appropriate size and up to 80 channels. It is conveniently accessible to all kinds of signals since it has the various expansion interfaces (We used the DANTE interface this time to facilitate network audio transmission). In addition, it can be quickly set and tested and signal distribution can be completed via only one key without the need to use complicated menus. It even has permission control to effectively prevent operation by mistake. Broadcasting is ensured since it is equipped with bridge, phase meter and two power sources.

Its simple and intuitive design which looks like an analog mixer makes it quite easy to use. The small screen of each channel may display the channel name and input header for easy monitoring. The eye-catching fader backlight makes it easy to identify different types of channels. It also has a built-in Lexicon reverb delay effect pedal to meet special performance needs.

It has an extended interface APP - ViSi Remote Control for use on the Ipad. The extended interface can be used as a split module of the mixer to facilitate simultaneous operation by different hosts. This allows the sound engineer to independently complete commissioning with the use of the extended interface. The host in the studio may adjust programs and monitor signals via the mixer, wile the sound engineer via the extended interface to adjust sound reinforcement signals. They are independently from each other. This allows the production of two different signals via one mixer and an extended interface while traditionally, two mixers are required.

Use of a sound mixer with an extended interface allows the production of two kinds of different signals while this is only possible with the use of two mixers in the past.

Shure ULXD™ digital wireless system and PSM300 digital personal wireless sound feedback system

The 4-channel ULXDTM digital wireless system is integrated into the 1U Shure ULXD4Q wireless receiver. This makes it compact, saving space and weight. The hosts and guests used the 4-channel ULXD2 handheld transmitters. Given the noisy environment, the Beta 58A dynamic microphone head was used to deliver the best sound quality. In addition, the 2-channel ULXD1 bodypack transmitter and headset microphone were used to facilitate small-scale performances by DJs or hosts.

The system uses the PSM300 digital wireless personal feedback, including a P3T digital wireless feedback transmitter and four P3RA bodypack receivers. The receiver allows freely selection of the MIX mode, so that the left and right ears can hear sounds of different channels. This allows pre-listening required for the live broadcast.

The ULXD™ wireless microphone and PSM300 wireless feedback are all digital wireless systems with highly secured digital transmission and can be 256-bit digitally encrypted. In addition, they used the rechargeable lithium battery with the power monitoring accuracy to one minute. They also allow equipment operation monitoring via the network to ensure broadcasting safety.

The studio used wireless devices in replace of the traditional wired microphones and headphones. This allowed maximum movement flexibility and freedom for hosts and guests.

The Shure ULXD2 handheld transmitter and Beta58 microphone head were used by hosts and guests in the studio.

In the performance, the host used the Shure ULXD1 bodypack transmitter and the WBH53 headset microphone.

The DJ used the Shure ULXD1 bodypack transmitter and the WBH54 headset microphone.

The host walked out of the studio to interact with the guests and the audience.

The audience participated in the interaction and interview

The system was connected to the DANTE network. The sound mixer, digital wireless system and computer audio workstation were all connected to the DANTE network, so that the computer audio input signals, wireless microphone input signals and multi-track workstation recording and output signals of the program were transmitted through the network. This greatly facilitated the system construction and reduced the costs of the wires used.

This pure digital audio system was connected to the Dante network using the ULXD™ digital wireless system, the PSM300 digital feedback system, and the Si Perforemer1 digital mixer which has an extended interface for remote control. It is convenient to construct and easy to use. Its remote control function frees the host from constrains of wires. It marked a new chapter of the EFP mobile box-mounted studio as it is portable and flexible to use and has complete functions. With this system, the EFP studio is really “moved up”!
