LA AUDIO C-400 C QUAD COMPRESSOR

The C400 C is a professional 4 channel compressor that can be operated as 4 separate
processors or linked as two independant stereo pairs. In Link mode, Channel 1 and 3
provide Master control and 'rms summing' is used to ensure that signals from both the
linked channels affect compression equally. Each channel has fully variable controls for
Threshold, Ratio, Release and Gain. The compression slope can be switched between
Hard or Soft knee, with Hard knee providing tight control of compression Ratio and Soft
knee a more progressive style of compression. Two Attack/Release modes are available;
Auto (program dependant) Attack/Release or Auto Attack with manuallly adjustable Release.
A low frequency Program filter can be switched into the sidechain to reduce the effects of
bass heavy material causing over compression. Each channel also has a sidechain insert
jack. Gain Reduction is displayed on an 8 segment LED bargraph. The Bypass and Link
switches also have led indicators. All Inputs and Outputs are electronically balanced and
can be switched between +4dBu and -10dBV operating levels.

Description

The alphaton Feedback-Controller FC-100 is a revolutionary product for every microphone
application including wireless types. It can provide effective feedback control to any sound
reinforcement situation. It can also eliminated string feedback in guitars and bass instruments
which are equipped with piezo or condenser pickups.
The FC-100 provides 6 to 10 dB of feedback protection by analysing the incoming signal,
detecting the presence of feedback and then notching out the feedback frequency.
The FC-100 relieves the sound engineer automatically. It works dynamically and eliminates a
feedback signal before it can grow into a peak. Internally a discriminator circuit detects the
presence of regenerative feedback and triggers the automatic equaliser to insert a notch where
the feedback peak is coming up. This normally prevents other peaks from developing but if they
do, the process is repeated at high speed, thus keeping feedback under control.

Manual

AXEL Compact telephone hybrid. Management of 1 wired PSTN / POTS line, electronically balanced input and output on XLR connector

Product Discription:

BoxTel MKII is an analogue telephone hybrid, designed to interface a telephone line with audio equipments. BoxTel MKII manages 1
POTS/PSTN line, whereas BoxTel GSM manages 1 GSM line to establish telephone connections where wired lines are not present.

A powerful internal microcontroller completely manages both BoxTel MKII and BoxTel GSM, allowing the configuration of the operating modes
via software. The internal microcontroller provides further functions such as adjustment of the line impedance according to the region,
visualization of the Send/Receive audio levels on the front leds, line detecting presence of a telephone line, buzzer with adjustable level,
AutoHook - automatic line hooking and answering after a certain number of rings. While BoxTel MKII is operative, its possible to exclude or
keep connected in parallel an external telephone set (Tel.Set).

The backlit Hook/Ring button on the front panel allows a quick management of the phone calls; each time a telephone call is incoming the
BoxTels Hook/Ring button starts to flash, by pressing it the operator answer the phone call. BoxTel MKII has the Line Detecting function,
which makes the Hook/Ring button switch on in presence of a telephone line.

BoxTel MKII and BoxTel GSM are devices equipped with an internal power supply enabling great audio performance: two separate
Send/Receive front potentiometers manage the audio level, with a total range of +/- 15dB. The input sensitivity is set at 0dBu while the
maximum output level is greater than +20 dBu.

The audio connections are separated for Send/Receive and are available over XLR electronically balanced connectors. A RJ11C connector
allows the telephone line connection (Tel.Line) and one more RJ11C connector performs the connection to an external telephone set (Tel.Set).
A GPIO port with optocouplers and open collector is provided to establish remote connections between BoxTel MKII and BoxTel GSM and
mixing console. It is possible to connect directly the Telco module of an Oxygen4, Oxygen5 and Oxygen7 console with BoxTel MKII/BoxTel GSM
by using a simlpe Pin-to-Pin cable. Internal universal power supply 90-264Vac/47-63Hz to operate worldwide.

Thanks to all of their features, BoxTel MKII and BoxTel GSM represent the telephone hybrids with the best quality/price ratio available on the
marketplace. BoxTel MKII and BoxTel GSM occupy ½ rack unit - LxHxD 22x5x13cm.
