Spectra Consoles

The Spectra-C/Ci and Spectra-T/Ti 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. Each of these VCA-based models is available with 24, 32, 40, and 48 mono input channels and all sizes feature 4 additional stereo line-input channels.

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/Ci and Spectra-T/Ti 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 Heart of the Console

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, but other EQ features differ for each console. Please read below to see the specific capabilities for the Spectra-C/Ci and Spectra-T/Ti.


Spectra-C/Ci EQ Section

The Spectra-C/Ci has 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.
  • High-Pass Filter Sweepable 20Hz To 400Hz At -12dB Per Octave
  • HF Is Switchable Between 8kHz And 12kHz Shelving
  • LF Is Switchable Between 60Hz And 120Hz Shelving
  • HMF Sweepable From 400Hz To 8kHz With 1 Octave Bandwidth
  • LMF Sweepable From 100Hz To 2kHz With 1 Octave Bandwidth

Spectra-T/Ti EQ Section

The Spectra-T/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/Ti's EQ and Insert functions.
  • High-Pass Filter Sweepable From 20Hz to 400Hz At -12dB Per Octave
  • HF Sweepable From 800Hz To 16kHz And Switchable Between Shelving And Asymmetrical Bell-Shaped Curve With 2/3 Octave
  • Bandwidth In Boost Mode And 1/4 Octave Bandwidth In Cut Mode
  • HMF Sweepable From 400Hz To 8kHz And Switchable Between 1 Octave Bandwidth And A Narrow 1/3 Octave Bandwidth
  • LMF Sweepable From 100Hz To 2kHz And Switchable Between 1 Octave Bandwidth And A Narrow 1/3 Octave Bandwidth
  • LF Sweepable From 20Hz To 400Hz And Switchable Between Shelving And Asymmetrical Bell-Shaped Curve With 2/3 Octave Bandwidth In Boost Mode And 1/4 Octave Bandwidth In Cut Mode
An Insert-ON switch with LED is provided on Spectra-T/Ti consoles. All other features other than the EQ parameters and the Insert-On switch are identical between the Spectra-C/Ci and Spectra-T/Ti consoles.

Spectra FOH Consoles are available with individual Balanced Send and Return TRS insert points (Spectra-Ci and Spectra Ti) or with single TRS insert points (Spectra-C and Spectra-T) where both send and returns are on incorporated into the same connector assembly. The availability of both types of insert configurations provide for easy incorporation into existing system that uses these wiring methods.

Servicing

We have designed all Spectra consoles 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.

A "P" suffix indicates that a redundant power supply (2nd power supply) and a console cover are included (standard "P" configuration). Lamps may be ordered individually as an option at additional cost.

*Stereo input channels may be operated in mono "Split Track" mode.

Manufacturers Note: We have prepared detailed dimensioned drawings for use by road case manufacturers and installers. Please note that we have included 1/4" PEM nuts on the inside-bottom of the chassis; useful for bolting a "dog house" assembly to the chassis, or when mounting the console in an installation to discourage theft.
