【 Weak current College 】 read KOSMOS PRO actuator

In sound reinforcement systems, peripheral devices on the audio system is also critical, on-site auditory effect is good or bad, is closely linked with the peripheral equipment. While in many peripheral processing equipment, the actuator is an influential processing equipment. Its application areas, theatres, Conference Hall, multi-function Hall, DISCO dancing and singing etc can all see it. Audio system to properly use the actuator may enhance audio clarity, can be about sex and expressive and increase loudness, sound more enchanting, reduce the auditory fatigue; increases the sound image of three-dimensional sense and sound isolation, improve the sound level, thereby enhancing the quality of the sound playback, more beautiful to listen to the result.
For members about a company from PEAVEY's low frequency Exciter-KOSMOSPRO. The equipment is original Kosmos adds new sound control options such as STRATOS (increased luminance); Barometric switch control (regulation XPANSE range). Other new controls include a modified range of ultra-low frequency stimulation THUD switches, is used to modify QUAKE in compact or loose the dynamic control of the response, as well as high-precision band switch input/output level tables, as an innovative design, powerful low-frequency actuator. It can produce results in excellent low frequency output, thus increasing the clarity of any sound system and accuracy.
1. front panel features
1) bypass switch
When this switch is turned on, in addition to the low frequency suspension frequency level control (when off the kosmos-bass), other features disabled, signal output directly, while a red led is lit.
2) input level control
The knobs adjust the input gain. In order to have a good-to-noise ratio and performance regulation should monitor the input level meter. Adjustment to 0dB, led most of the time flashing, and the clipping indicator LEDs light does not shine as well. Because the center anchor is unified gain points,if the input level is too high, heavy bass may lead to clipping and distortion effects signal effect.
3) level selector switch
This machine level meter can display after level control after the input level, output level can also be displayed by level selector switch to switch the two-level display status. When this switch is pressed display output level; when the lift is display the input signal level. LED level indicator with yellow and red colours, yellow led light indicates warning, while a red led is lit indicating how there is 4dB cut off. During testing, when you see the yellow led is lit for a long time, it is necessary to note the level adjustment. In order to avoid signal overload, whenever possible, do not let the red light is lit, so as to ensure the best signal.
4) output level control
The knob to adjust the output level of the device. The centre point is unified gain points, 10dB gain can be used. When the bypass switch is pressed, the button does not work. The knobs are also adjustable S/PDIF output level.
5) subwoofer cutout switch
The switch from left and right main output removal after QUAKE and THUD-treated low frequency. It will not be removed from the program's normal bass. When you use 3-way speaker system, you can make all the increase of low frequency output from the Subwoofer port only. When the left and right speakers cannot produce low frequency processing extra, this is the best way to increase low-frequency. By XPANSE and STROATS signal is always sent to the primary output and are not affected by the impact of the switch.
6) pitch switch
Used to change the two different sizes of low-frequency harmonics between speakers of the base frequency. The "OUT" location has a higher centre frequency, which is more suitable for small speakers. "IN" position the center frequency down, in order to allow big speakers lower bass. If there is no significant difference, maybe the speaker does not exhibit reduced bass, it is recommended to use small speaker settings. If you modify the minimum frequency, the power amplifier has been working to bring to the speakers.
7）QUAKE
This switch can produce an even lower than the sound source a octaves of integrated low-frequency signal. It and DYNAMICS, corresponds to a specific frequency (frequency and amplitude) produces a natural low-frequency harmonics. When the input signal is beyond the scope of the set, it cannot go beyond this frequency effects processing. It also can enhance, increase the proportion of low-frequency frequency of music, particularly the bass drum. Because it also push for low-frequency section, care must be taken not to produce extra, extra low-frequency level so that the power amplifier is distorted or damaged speakers, especially when using small speakers.
8）QuakeActive
The reverse gear is used to indicate the QUAKE activity. As a reference, in the light does not light, if available, low frequency information exist, although the level may be very small, low-frequency harmonics are still in production. If there are no bass component sources, this lamp is not lit.
9）Dynamics
Some want low-frequency bass natural harmonic followed closely; there are times when you want it follows some loose, QUAKEDYNAMICS control can be adjusted to it. Follow tight, the increase hit effect; follow pine increases more bass, like the impact of a suppressed the bass drum, there is no impact on non-rejection of bass drum sound.
10）THUD
This control is the low-frequency harmonics QUAKE by adding a special chrome (natural instead of synthetic), it's about regulating a octaves above the low-frequency harmonic and balanced manner, using low-end. THUD and QUAKE on tweak the wave, the phase change, it will effectively modify waveform and amplitude, sound may and what you would expect.
11）DEEPER
It narrows down the THUDCircuit, delete parts of the bass frequencies. This makes it much more low frequency adjustment.
12）XPANSEbr>Use this switch in conjunction with BAROMETRICS, you can increase the frequency and bandwidth, minimum stereo position is the flatness of the settings. Clockwise rotation, left/right sound like a wider, while at the same time increase the sharpness. It is designed to maximize the sound of tension (elevating) mixed, and decrease the speaker's dressing filtering effect. It does not put the Mono sources into stereo, but it will improve the signal.
13）BAROMETRICS
This knob control XPANSE circuit between the two process phase. When counterclockwise (intensive) phase of dominant, clockwise rotation (thin) intensity high frequency increase. A typical setting close to the middle position.
14）STRATOS
This knob to the sound source to increase high-frequency harmonics, the frequency range above XPANSE range. It gives boring sources increase crisp effect.
15) bass
KosmosPRO internal has a low frequency divider 90Hz. Heavy low signal is QUAKE, THUD and from 90Hz divider of the aggregate of the low-frequency signal; this knob will change the output level. When the bypass, the increase of QUAKE and THUD portion will be dropped, leaving only the low frequency divider for low frequency signal. In this mode, is a standard bass control.
2. the back-panel features
1）S/PDIF
This is a stereo digital input output interface, the connection to other digital devices, such as computers or DAT recorder. If the default is no, then enter 44.1kHz will sync to the current frequency (up to 48kHz). If it and enter the clock locked, syncs indicator light; if there are errors of data err led light. If you select S/PDIF KosmosPro input modes, digital inputs is the only connect to the internal analog processing, but it will always synchronize internal sampling rate (if it has a clock). S/PDIF digital output has always been there, and about the same as the main output and. Digital full scale (0) is equivalent to an analog device pointer position (+ 22dBu).
2) subwoofer output
This is a balanced output 6.35mmTRS e, for balancing (6.35mmTRS plugs) or non-equilibrium (standard 6.35 plugs). Output also provides a signal to the subwoofer amplifier (line signal).
3) left and right output
Left and right output is electronic balance type, the Add method and the bass output as [② feet (or "tip" for cathode]. Card Lennon and 6.35mmTRS plugs directly parallel wiring. As balanced and unbalanced mixed into the same channel output, it becomes unbalanced. In mono mode, have left/Mono to mono output signal.
4) input
Left and right input is the balance of ② feet (or "tip" as the cathode. Card Lennon and 6.35mmTRS plugs directly parallel wiring. When you use a Mono signal, received left/Mono interface (card Lennon or 6.35mmTRS) and press the MONO selection switch.
5) input selection switch: you can select the simulation (card Lennon and 6.35mmTRS) input or digital input; select one another will be disconnected. This switch affects the left and right input. When the switch is selected in the S/PDIF digital input, MONO switch will not work.
6) MONO selection
If you use only one input channel KosmosPro, this switch should be pressed. It guarantees between left and right signal processing in the appropriate range. This switch does not S/PDIF unit.
3. the application of the system
KosmosPro in system connection generally use the threaded mode, and before the power amplifier, but then after the other peripheral equipment.
String into left and right channels, compensation, comprehensive voice signal because the left and right channels in various sound sources are mixed together, only for the overall compensation. Before the power amplifier, because power amplifier frequency response curve best, generally within 100kHz 10Hz — its gain change 0-0.2dB and actuators on the treble and overtone of compensation only 0.5-1dB, through the power amplifier is capable of varying success rate signal, direct drive speaker. If the add-in before other peripheral equipment, most likely because these devices are ideal frequency response performance, compensates the quantity is small in the treble and overtone constituents and lost, in this connection, it is usually a normal drive level.
