features

SPOT1500 represents the “light” version of the SPOT 2500T: there is no bass cabinet with it’s dedicated amplifier. It is a high directivity, long throw compact system, characterized by extremely high intelligibility, even at long distances, making it the perfect choice for live applications. This system was designed to simplify the task of assembling clusters by simply placing multiple enclosures side-by-side when wider horizontal dispersion is required. SPOT1500 is equipped with class D amplifiers controlled by the Montarbo DSP loudspeaker processor (56 bit, 180 MHz, 24 bit converters) which provides filtering, equalization, delay, limiting and diagnostic functions. This DSP utilizes an advanced algorithm for the real time control of both the power output and the temperature (both internal and external) of the amplifier; it also includes a dedicated standby function which results in reduced power consumption when no signal is present.
5 presets are available, one of which may be customized by the user and loaded into the DSP, thus adapting the speaker’s acoustic response to the user’s personal taste. The Internal DSP controller also provides an auxiliary output that may be used to drive an external subwoofer, be it equipped with internal filters or not.
The presets can be modified by means of the Montarbo proprietary software program RAConLSTM with the LD2.4 USB interface (optional device). The remote control allows: programming and storage of one preset in the DSP and the creation of an unlimited library of personalized settings in the PC; adjustment of the frequency response by means of a 10 filter “fully parametric” equalizer; adjustment of the delay time and of the output level of each speaker system; monitoring of the power amplifier’s status (temperature, protection circuits, limiters and thermal alarms); selection of the type of subwoofer used.



• 2 class-D amplifiers (with switching-mode power supplies)
that can supply a total of 1500 Watts EIAJ
(1000 W for the LF drivers, 500 W for the HF).

• 135 dB max SPL.

• 15” woofer with 4” voice coil, featuring a shielded front-mounted neodymium magnet.

• HF driver with a 1.4” throat and a 3” voice coil, featuring a neodymium magnet and titanium diaphragm.

• High directivity (50° H x 40° V) wave-guide horn.

• Montarbo 56 bit DSP, 180 MHz, 24 bit converters.

• Dedicated standby function.

• Processed auxiliary output allows to drive an external subwoofer.

• 5 presets one of which may be customized and loaded into the DSP.

• Presets remote control and customization by means of the proprietary software program RAConLS™ and  the optional LD2.4 USB interface.

• With a single LD2.4 USB interface it is possible to operate up to 10 speaker systems of the SPOT, WIDE and FULL series.

• The geometry of the cabinet allows for easy construction of clusters.
A 3-system cluster results in a 150° horizontal coverage.

• Birch plywood cabinet, finished with anti-abrasion paint.

• Threaded studs (M10) for safe and simple suspension; adapter for a supporting pole; 2 ergonomically designed handles.


Applications

• SPOT1500 is perfect for live music, but its excellent vocal/speech intelligibility at long distance qualify it as a highly recommended option for conventions.

Side Fill mungkin yang artinya(sisi isi atau sisi isian) barang kali si penemu kalimat ini bermaksud (isian   sound  yang ada di-sisi) Side Fill juga termasuk Monitor Panggung hanya saja speakernya agak lebih besar ketimbang Floor control. Bedanya Side Fill dengan Floor control adalah. kalau Side Fill isian bunyi sama dengan speaker utama( Speaker Wing) sayap  kanan sayap kiri cuma ber level rendah .Sedangkan Floor Control (yang ada di lantai) monitor panggug isianya bunyi tergantung keperluan  misal; yang ditengah panggung buat monitor vokal yang dominan juga vokal,gitar tipis snar drum agak tinggi dikit ketimbang gitar(snar buat ketukan si penyanyi) dan seterusnya tergantung selera. System Side Fill ini biasanya dengan three way,,pasive maupun aktive tergantung selera Pokoknya semboyan kita bagi Engineering melayani pembeli,,memanjakan musisi salah satunya.

Q1 speaker 10x2 inch tambah 1 driver 2 inch model box speaker ini baru digandrungi oleh pelaku rental sound system karena dengan designnya yang imut tapi menghasilkan suara yg cetar membahana. Box speaker Q1 dengan system 2 way,mid frequensy dan high frequensy dan didaamnya dipasang crosover pasif secara terpisah,,cros mid sendiri juga high sendiri,walaupun nantinya juga mendapat umpan dari sebuah power amplifier yang sudah menghasilkan keluaran mid atau high yang berasal dari filter crosover aktif. Kinerja box ini berkisar 100 hz sampai 17 khz,,jadi harus pandai panda kita mengatur crosoer aktif utuk menyesuakan carakter dari speaker itu sendiri karena kita merakit sendiri. Jadi input dari spekon ada dua jalur pin ke empatnya di pakai semua,,untuk mid dan high. ada cotoh gambar berikut Handel disaping kiri dan kanan disamping buat pegangang juga untuk jalan obeng atau kunci L untuk membaut speaker.
