Fohhn Audio PT-7-RS4 Sound Package Used, Second hand

Ref. code: 1.01.391

PT-7

FOHHN expands its PERFORM-SERIES with the PT-70 ? a high performance, 2-way loudspeaker system with cardioid functionality that has been specially developed for concert sound and touring applications. The new loudspeaker makes an ideal sound system for concerts in tents, halls and clubs, or for town festivals and smaller open-air events. It also acts as a solid extension for line arrays and large Beam Steering systems. For the rental market, the PT-70 has many applications as a multifunctional loudspeaker system.
The PT-70 contains two 12" chassis with compression chamber and horn, plus a 1.4" compression driver with CD horn. It features a passive crossover which splits up the loudspeaker?s audio signal. An Intelligent Protection Circuit (IPC), a voltage-controlled semiconductor circuit, protects the high frequency driver from overload - quickly and reliably.
The loudspeaker system also features CONVERTIBLE DISPERSION TECHNOLOGY (CDT), which is registered as a utility model. This technology enables the PT-70 to be switched between cardioid and vented operation. In cardioid mode, the sound dispersion at low-mid range frequencies is effectively reduced at the system?s back. Thus first-class sound reproduction and speech intelligibility are ensured. The PT-70 has been solely developed for operation with FOHHN speaker presets - especially with FOHHN Class D amplifier D-2.1500: The system?s equalizing occurs within the FOHHN DSP, which also includes all of the protective functions that are required for a safe operation. Together with this amplifier and FOHHN subwoofers, the PT-70 delivers excellent results.

Used Fohhn Audio AG


Fohhn develops and builds professional sound systems for mobile applications and fixed installations. In our innovative sound systems, mechanics, acoustics and electronics form one unit and we have been using self-developed digital technologies since 1993.
Our Fohhn Beam Steering Systems are available in all conceivable sizes as well as a wide range of sound point sources, line source speakers, line arrays, ceiling speakers, high-performance amplifiers, accessories and software.
Therefore we provide optimal solutions for a wide variety of application areas – from a small conference room to live PA in large halls and stadia. We are a genuine partner for our customers over the entire project run-time – from planning to acoustic simulation and calibration, to on-site project completion.
At Fohhn, optimum visual integration meets the best sound quality, simple operation and bespoke sound system concepts.
Furthermore, our research, development and production exclusively take place in Nuertingen – all products are made in Germany.

Efficiency Rating: Level of sound output measured at a prescribed distance with a standard input power. Efficiency rating standard is 1 watt (2.83V at 8 ohms) at 1 meter over a specified frequency range and is measured in decibels.

Equalization: Loosely, any type of relative frequency adjustment. Specifically, the process of changing the frequency balance of an electrical signal to alter the acoustical output.

Equalizer: A component designed to alter the frequency balance of an audio signal. Equalizers may be graphic, parametric, or a combination of both.

Fade: A gradual increase in audio, i.e. a fade-up, or a gradual decrease in audio, i.e. a fade-down.

Feedback: The transmission of current or voltage from the output of a device back to the input, where it interacts with the input signal to modify operation of the device. Feedback is positive when it’s in phase with the input and negative when it's out of phase.

FM: Frequency Modulated.

Frequency: The number of cycles (vibrations) per second. In audio, audible frequencies commonly range from 20 to 20,000 cycles per second (Hz). In video, frequency is used to define the image resolution. Low-frequency video images depict large objects or images. Higher frequencies depict smaller objects (finer details.

Frequency Response: A measure of what frequencies can be reproduced and how accurately they are reproduced. A measurement of 20 to 20,000 Hz, 3dB means those frequencies between 20 and 20,000 Hz can be reproduced no more than 3 dB above or below a reference frequency level.

Full-Range: A speaker designed to reproduce the full range (20 Hz to 20 kHz) of audio frequencies.

Gain: Increase in level or amplitude.

Gooseneck: This refers to a microphone with a flexible neck that is most frequently attached to a podium or lectern. It is designed to allow the speaker to raise or lower the microphone to a suitable height.

Graphic Equalizer: A type of equalizer with sliding controls that creates a pattern representing a graph of the frequency-response changes. Raising sliders boosts the affected frequencies lowering sliders cuts (attenuates) the affected frequencies.

HDCP: High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent unauthorized duplication of copyright material.

HDR: Hard-Drive Recorder. Device that uses a computer hard drive to store compressed digital audio and video signals.

High Pass: A filter that passes high frequencies, and attenuates low frequencies. Same as low cut.

Hz: Hertz or cycles per second. Something that repeats a cycle once each second moves at a rate of 1 Hz.

Incue/Inq/In-Point: These words all refer to the initial few seconds of audio signifying the beginning of the production.

Integrated Amplifier: A combination preamp and amplifier.

Impedance: A measure of the impediment to the flow of alternating current, measured in ohms at a given frequency. Larger numbers mean higher resistance to current flow.

KHz: Kilohertz or one thousand Hz.

Lavaliere: A small microphone that attaches to clothing, allowing the speaker to have a hands-free presentation.

Line Array: A group of speakers that have been arrayed or ” built up” in the vertical or horizontal plane, which allow for a highly consistent sound field. A Line Array is perfect for medium to large audiences.

Line-Level (Low-Level): A level of electrical signals too low to make the average speaker move sufficiently. Amplifiers receive line-level signals and amplify them to speaker level.

lockout: The final words of a segment used to signify the production’s conclusion.

Low Pass: A filter that lets low frequencies go through but doesn’t let high frequencies go through. Same as high cut.

MHz: Megahertz, or 1 million Hz.

Midbass: The middle of the bass part of the frequency range, from approximately 50 to 100 Hz (upper bass would be from 100 to 200 Hz). Also used as a term for loudspeaker drivers designed to reproduce both bass and midrange frequencies.

Midrange: The middle of the audio frequency range. Also used as a term for loudspeaker drivers designed to reproduce this range.

Mixer: This is the unit in which audio signals are directed from. A mixer provides for both mic and line input combinations while allowing you to control one or more outputs.

MLP: Meridian Lossless Packing. Encoding format that is able to completely reconstruct the original signal at the receiving end. No information is lost or discarded, regardless of how trivial it might be. Used to encode six channels of high-resolution audio on DVD-A.

Mono: Monophonic sound. One channel.

MP3: MPEG-1 Audio Layer-3. Compression scheme used to transfer audio files via the Internet and store in portable players and digital audio servers.

Natural Sound (NATS): The nonverbal audio that occurs in a non-studio setting. NATS can be used to help characterize the setting.

Noise: An unwanted portion of a signal such as hiss, hum, whine, static, or buzzing.

Nonlinear Editing: Digital audio systems that allow for clips to be extracted without affecting the master recording.
