19 июл. 2017 г. Ohms Law can be used to determine the impedance of a speaker load using the formulas below. Speakers in Parallel: ZIN = Z1 + Z2 + Z3 . . . 1. 1.
Many loudspeakers are placed across this “70 Volt” speaker line using distribution transformers at each speaker to convert this high voltage back down to the
A transformer at the power-amplifier output steps up the voltage to approximately 70 volts at full power. Each speaker has a step-down transformer that matches.
Speaker line voltage select: set to 100 volt or 70 volt position depending Do not attempt to suspend multiple speakers on the same set of chains or brackets.
the speaker output. In 70 and 100 volt speaker lines the power of all speakers in the chain must be added. The total power MUST be lower than or equal to
It requires no transformer coupling to drive. 70 volt speakers directly. The 70V Output: Spring loaded terminals to be connected to 70 Volt speaker connec-.
Before installation or use be sure to carefully read all the instructions in this section for correct and This speaker is designed to operate on a 70 V.
Ohms Law can be used to determine the impedance of a speaker load using the formulas below. Speakers in Parallel: ZIN = Z1 + Z2 + Z3 . . . 1. 1. 1. 1.
Both high-impedance (70V/100V lines) models and low- impedance (8?/15W model 16?/30W model) TOA's TC Series Reflex Horn Speakers are designed for both.
Never connect the speaker to the amplifier's 70 V or 100. V line (high impedance) when setting the LINE switch to the LOW position (4 ? or 8 ?).
Allows the use of 70 or 100 Volt speakers with any Sonnex® system. > Enables the connection of multiple speakers to a single amplifier output.
Ceiling Speakers. • Commercial Sound. • Connect four 70V transformer inputs to outputs of a quad Amp (Samson. Servo 4060 or Servo
1. Do NOT connect the 70V speaker line to the power amplifier yet. 2. Install a transformer at each speaker location or use speakers with built

The TOA P-906MK2 P-912MK2 and P-924MK2 Power Amplifiers deliver up to 60 watts
selections for 100 volt line and five selections for 70 volt line adjustable via a rotary switch under the rear cover These four models each have five 70 volt trans-former taps ranging from 2 5 watts to 30 watts All systems are easily mounted in vertical or horizon-tal positions with a wide range of optional mounting
amplifiers with 8 ohm outputs and built-in output transformers for 25-volt and 70-volt lines designed for commercial and professional sound applications The P-150M and P-300M deliver 150 watts and 300 watts respectively with 8 ohm loads or with 25-volt or 70-volt distributed system loads
The speaker outputs of the amplifier are 4 8 25V and 70V Connect speakers to one of these outputs Class 2 wiring may be used Since these outputs consist of 8 25V and 70V via the output transformer (matching transformer) and direct output of 4 the connecting method differs in each case

The TOA A-901 A Mixer Power Amplifier has transformer- isolated output terminals to match 4- or 8-ohm speaker systems or speaker distribution systems may be connected to the 25 or 70-volt terminals The A-901 A can be rack mounted by using the MB-920 Rack- mounting Bracket Accessory TOA Corporation133-02-735-OA
While the power amp might be a few hundred watts, most speakers have a transformer that is designed for maybe 5 or 10 watts. Even with all these drawbacks, there are things that 70-volt systems can do that regular systems cannot. One, as you can see from the chart above, is distance.
70V speakers produce high bass and crispy music. But their wiring system is the best for spreading the sound for more than 4 speakers. On the other hand, 8 Ohm speakers are for confined rooms where high-quality sound is required. They require less power and are less expensive. Are you still confused? Don’t worry, we have your back.
Complete TOA 7DT midrange horn speaker. Tested, plays music as it should. TOA ELECTRONICS H-1 2-WAY INTERIOR Wall OR Ceiling NEW (Atmos etc.!) TOA F-1300WT Wide-Dispersion Speaker System. New.
This material provides great durability, a good look, and convenience in cleaning. However, the TOA 60 version is lighter than the TOA 70 version (21 lbs vs 23.1 lbs), while they have the same dimensions. So it would be a breeze to transport the 60 model, for example when you want to bring it outside for a family party or picnic.
