![]() Choose between 2 channels each at 50 watts (model IZA 250-LZ, 4Ω ) or 1 channel at 90 watts (model IZA 190-HZ, 70/100V systems) for loudspeaker installations High- and low-impedance models available.Amplifier outputs can be muted remotely via a contact closure.Fine tune the sound with front panel treble and bass tone control knobs (+/-6 dB 100 Hz and 7 kHz).Auxiliary input on front panel allows quick connection with mobile devices.Front panel allows for quick connection of hand-held microphones via an XLR/TRS combination connector.Bose Volume control with A/B switch enables access to amplifier volume level and source selection from remote locations.Source select and master output level can be easily controlled from the front panel.Output level (trim) controls available for adjusting individual channel outputs relative to the overall master level.Input source levels can be adjusted with independent gain controls.Five inputs: two stereo line inputs, one mic/line input, one page input and one auxiliary stereo line input.Four rear panel DIP switches offer flexible operation modes: Page Normal/Bypass Master, Output Mono/Stereo, Front Mic Mix/Duck, Aux Out EQ/Flat.System set up is done locally from the front and rear panels.Bose Opti-voice® paging automatically provides a smooth transition between music and page signals.Bose Dynamic Equalization circuitry automatically adjusts tone based on the output level to maintain tonal balance at all volume levels.With a switch on the rear panel, selectable Bose loudspeaker EQ presets optimize performance of FreeSpace FS2 and FS4 loudspeakers.New origin that other objects are defined with respect to. The coordinates of every other object in the simulation, i.e. Passing geometry_center=c is equivalent to adding the c vector to The coordinate system used in Meep (for example, to put the origin at theĬorner). Defaults to (0, 0, 0), but changing this allows you to shift ![]() ![]() Geometry_center - Specifies the coordinates of theĬenter of the cell. Objects making up the structure being simulated. The basicĭatatypes, like integer, boolean, complex, and string are defined by ![]() The classes, complexĭatatypes like GeometricObject, are described in a later subsection. In bracketsĪfter each variable is the type of value that it should hold. Geometry_center: Union] = Vector3,Īll Simulation attributes are described in further detail below. Material_function: Optional]], ]] = None,Įpsilon_func: Optional]], float]] = None,Īccurate_fields_near_cylorigin: bool = False, K_point: Union, bool] = False,Įxtra_materials: Optional] = None, Symmetries: Optional] = None,ĭefault_material: = Medium(), Sources: Optional] = None,īoundary_layers: Optional] = None, Minimally, a simulation script amounts to passing the desired keyword arguments to the Simulation constructor and calling the run method on the resulting instance.Ĭell_size: Union, NoneType] = None, The Simulation class is the primary abstraction of the high-level interface. One of Sx, Sy, Sz, Sr, Sp, EnergyDensity, D_EnergyDensity, H_EnergyDensity for, ,, , (components of the Poynting vector ),, ,, respectively. These are additional components which are not actually stored by Meep but are computed as needed, mainly for use in output functions. One of Ex, Ey, Ez, Er, Ep, Hx, Hy, Hz, Hy, Hp, Hz, Bx, By, Bz, By, Bp, Bz, Dx, Dy, Dz, Dr, Dp, Dielectric, Permeability, for, ,, ,, ,, ,, ,, ,, ,, ,, ,, , ε, μ, respectively. Specify a particular field or other component. Metallic (i.e., zero electric field) or Magnetic (i.e., zero magnetic field). Specify particular boundary in the positive High (e.g., + X) or negative Low (e.g., - X) direction. One of X, Y, Z, R, P for, ,, ,, respectively. These should be one of the following constants (which are available directly via the meep package): a field component or a direction in the grid. Several of the functions/classes in Meep ask you to specify e.g. Ī big number (10 20) to use for "infinite" dimensions of objects. Perfect_magnetic_conductor Ī predefined material type corresponding to a perfect magnetic conductor at the boundary of which the parallel magnetic field is zero. Perfect_electric_conductor or metal Ī predefined material type corresponding to a perfect electric conductor at the boundary of which the parallel electric field is zero. Two aliases for a predefined material type with a dielectric constant of 1. These are available directly via the meep package.
