Opis
GTO-DF is mechanically identical to, and acoustically matched with, the GTO full-range cabinet, so it can be easily added to a flying array. Unique to the GTO-DF is a vertical dispersion range of zero-degrees to minus 25-degrees to ensure precision aiming of the sound into the audience and not onto the stage. The development of this acoustic lens has facilitated a much more compact design than is normally associated with products of this type. The proprietary waveguide offers 120-degrees of horizontal coverage from 315 Hz to 17.5 kHz.
The GTO-DF is intended for large-scale applications, as part of the GTO-turnkey solution. The GTO range is ideally suited to projects that demand no-compromise audio quality. This product is capable of outstanding electrical to acoustic power conversion. The GTO-DF has a useable frequency +/-3 dB from 250 Hz to 17.8 kHz.
The sensitivity is 105 dB SPL (for the mid frequencies) and 101 dB SPL (high frequencies) in free field. A maximum continuous AES input power of 800 W (mids) and 250 W (highs) will provide a power output of 134 dB SPL in free-field (mids) and 125 dB SPL (highs), while peak output power values can reach 144 dB SPL (mids) and 135 dB SPL (highs).
The GTO-DF’s high quality cabinet is constructed from 15 mm (phenolic-glued) baltic birch plywood and includes bracing throughout to increase the overall cabinet rigidity. The outer finish applied is a scratch-resistant, waterproof black paint. GTO trolley-board designed for ‘2-up’ aids handling and transporting on even or uneven surfaces. Recessed integrated handles in the side panels of the cabinet are used for a positive grip during handling. Weather protective shower caps also form part of the turnkey -package.
Connection to the loudspeaker comes in the form of two types of connector, wired in parallel. These are: one NL4 wired pins 1+/1- for midrange drivers, pins 2+/2- for HF compression drivers plus one LKI-8 wired pins E/F for midrange drivers and pins G/H for HF compression drivers.
