APB-DynaSonics Spectra Series
Spectra-C, Spectra-Ci, Spectra-T, Spectra-Ti
24, 32, 40, 48 and 56 channels

The Spectra Series are high performance analog consoles from APB-DynaSonics designed to offer truly exceptional sound quality, versatility and reliable performance in a range of fixed installation and touring sound applications.

The Spectra-C and Spectra-T consoles feature TRS inserts while the Spectra-Ci and Spectra-Ti include balanced insert sends and returns on separate 1/4" phone jacks to more easily match the existing wiring schemes of production companies.

Each of these VCA-based models is available with 24, 32, 40, 48 and 56 mono input channels and all sizes feature 4 additional stereo line-input channels. A 24 channel mono-input expander is also available for use with all of the available models for the entire Spectra Series.

Feature rich, Spectra consoles include VCA control on inputs and outputs, mono/stereo/3-speaker LCR monitoring, and inserts on all primary outputs, including the Auxes and Matrixes. The Master VCA output fader can simultaneously control the levels of Left, Right, Center, Mono and any of the four Matrix outputs. The Spectra-C and Spectra-T represent a unique, inventive approach to design that literally redefines the potential of live-performance analog consoles for a new generation of users.

Spectra EQ
The primary difference between the Spectra-C/Ci and Spectra-T/Ti consoles is in the EQ sections. Both models include a variable high-pass filter (20Hz to 400Hz) with ON switch and LED. All other features other than the EQ parameters and the Insert-On switch are identical between the Spectra-C and Spectra-T consoles.

Spectra-C and Spectra-CI have a 4-band EQ section with Shelving High and Low bands, each switchable between two frequencies. Each of the two bell-shaped mid bands are sweepable over a 20:1 range and have a 1 octave bandwidth. An EQ ON switch with LED is also included and always on.

Spectra-T and Spectra-Ti EQ is sweepable in all four bands and includes shelving/bell switches on the HF/LF frequency bands. The HF/LF bell mode features an asymmetric response, with 2/3 octave boost and 1/4 octave cut. The two mid bands are switchable between 1 octave and 1/3 octave bandwidth in both boost and cut. Separate ON switches with LED are provided for Spectra-T's EQ and Insert functions.

Servicing
Spectra consoles are designed to be easily serviced. Replacement of a module block requires only the removal of 6 front panel screws and 4 ribbon cables in total. It is not required that the console be removed from its installation or road cases for the replacement or repair of a module assembly. A mother/daughter board construction is employed throughout with all primary electronics on individual plug-in circuit boards using gold-plated connectors. Even the fader uses plug-in leads for easy service or replacement.
