The ATB-300 Audio Toolbox AES Synchronous Audio Switcher
NEW! The ATB-300 Audio Toolbox from BDI is a rack mounted solution to switching and routing in the digital or analog domain. The ATB-300 can be ordered in eight different configurations. The basic configuration is the ATB-300-1 that accepts four AES3 inputs, that can be switched and routed to four AES3 outputs. If analog input is required in addition to AES3, the ATB-300-2 has four analog balanced stereo inputs in addition to the four AES3 inputs. The ATB-300-3 has AES3 I/O and analog output, if AES3 and analog I/0 are required. The ATB-300-4 is analog only L/R I/O and the ATB-300-5 provides four AES3 I/O and four balanced stereo I/O.

The 5.1 Plus Stereo Monitor Controller
The 5.1 Plus Stereo Monitor Controller is designed to accept a multi channel 5.1 surround sound mix, and provides metering and one-knob control of the entire surround mix. Perfect for television, movie post production and control room environments where controlling a 5.1 multi channel mix via a single volume knob is needed.
The 5.1 Plus becomes transparent to the mix, but provides excellent metering, and smooth volume control with a spare stereo channel available to monitor a stereo mix, or any other content that you wish to hear in the control room. Please click here for more information.

The ACS-400 Audio Controller
The ACS-400 is an eight channel microphone preamplifier/line input audio controller with programmable remote control of channel level, dim and mute functions. An optional remote control panel is available to provide level and mute control of each channel. The unit can be configured so that one volume control can be used to control six channels for a 5.1 mix and still have a pair of channels for a separate stereo mix, in just one example. Volume control can be programmed for individual channel control or any combination of channels. This product is intended for applications where level management of multiple channels is required or where multiple microphone preamplification channels is required. Each channel is selectable for microphone or line input. All outputs provide nominal +4 dBm balanced output. Click here for more information.

The ACS-300 Audio Controller
The ACS-300 Six Channel Audio Controller was created to meet the demands of today's multi-channel audio environment. The unit is designed to accept six channels of audio and, upon remote control, dim all six channels by 10-, 20- or 30-db. A second command line mutes all channels simultaneously. There are also separate mute command lines for individual or grouped channel muting. The unit can support up to six channels simultaneously, three stereo pairs, or six individual channels. Uses include control of control room or studio monitors for 5.1 multi channel audio systems such as those found in digital television or HD radio applications. The overall dim function can be used for paging or intercom applications where it is desired to reduce the level of an entire monitor system so that page or intercom audio can be heard more clearly throughout a facility.

Base Band Audio Products
The LPF-100 Composite Low Pass Filter
NEW! The LPF-100 Composite Low Pass Filter is a modern approach to filtering FM composite base band stereo audio. The LPF-100 offers at least 15 dB of noise reduction at 67 KHz and more than 30 dB of attenuation at 100 KHz. Distortion generated by aggressive processing techniques, noisy STLs and stereo generator birdies can now be suppressed effectively without materially impairing stereo performance. The LPF-100 is a tenth order, linear phase filter approach that is designed to work with any stereo generator output. The unit accepts 3.5 VPP base band audio and provides three level controlled, isolated 3.5 VPP nominal filtered outputs. Click here for more information.
