The MULTIGATE PRO XR4400 provides four frequency-selective expanders/noise gates in a single rack space. Each section comprises an ultra-fast gate, a program dependent expander, a filter section and precision meters indicating both threshold point and gain reduction.
The included side chain parametric filters allow the user to fine-tune control signals so that the gate reacts only when required. The Interactive Attack Control (IAC) circuit analyzes the program material to calculate the attack time of the gate. Separate hold and release controls offer additional flexibility. The XR4400 has a switchable operating mode for the gate and expander. With the MODE function off, the unit works in gate mode using an extremely fast attack time, thus preserving the transient details of the program material. In expander mode, the device analyzes the shape and dynamic contents of the input signal to calculate the control time parameters. The result is that vocals, instruments and complex mix signals can be cleaned up without audible clicks or other detrimental effects.
A couple function on the XR4400 provides a great deal of flexibility to link the expander/gate sections in a master/slave configuration.

The dbx 560A Compressor/Limiter offers legendary VCA-based compression in the increasingly popular 500 Series format. dbx has a much-heralded history with modular processors dating back to our 900 Series and the 560A continues that tradition.
Featuring the same switch-selectable OverEasy? and Hard Knee compression curves as our industry-standard dbx 160A rackmount processor, the dbx 560A will be your new workhorse compressor! With extremely wide-ranging threshold, ratio and output controls and true RMS level detection providing the most natural-sounding dynamics processing available, the 560A will provide punch to drums, bass, vocals, almost anything! It’s also versatile enough to go from subtle compression to "brick wall" peak limiting. |
mic/line for the BLU-80, BLU-32, BLU-16. |
The dbx 530 Parametric EQ offers a unique degree of equalization flexibility in the popular 500 Series format. Based upon the classic dbx 905, the dbx 530 is an uncompromising equalizer offering true, fully parametric operation of all three filter bands! dbx has a much-heralded history with modular processors dating back to our 900 Series, and the dbx 530 continues that tradition.
The dbx 530\'s overlapping bands each offer control of frequency bandwidth (Q) and up to 15dB of reciprocal cut or boost to provide exact, complimentary filter action for the most demanding of equalization needs. For problem situations requiring the removal of spurious signals, each of the bands can be independently switched into ?infinite notch? mode without affecting the operation of others. In situations where a shelving equalizer will produce better results than a peaking one, the 530’s high and low bands can be independently switched from peaking to shelving operation. You can also make instant affected/bypassed comparisons using the 530\'s ?On? switch.
Load up your 500 Series rack with dbx 530 Parametric EQs and cut your way through mixes like an audio surgeon! |
An elegant slim-line device contains all the functions required by a system for distributing different musical programmes in homes for multi-room sound systems and commercial premises.
Three different musical programmes and one for paging can be transmitted in five mono zones, or alternatively four zones, one of which is in stereo. It is also possible to extend the number of zones to ten using a simple connector to interlink two systems. The system has five amplified 20 W / 4 ohm outputs. For each of the five zones, a direct auxiliary input is available for connecting sources such as CD players or mixers to be used exclusively for one zone/room.
The back-lit display and function keys make it possible to access all the menus for configuring and adjusting the system: Volume, Tone, Loudness, Output settings, VOX.
