LA AUDIO BCL-20 DUAL-STEREO BROADCAST COMPRESSOR-LIMITER

The BCL20 is a broadcast quality dual Compressor/Limiter with a built in De-Esser
function, designed for FM transmitter protection and disc mastering as well as PA
and studio applications. The unit may be operated as two independent channels or
linked for stereo programme processing. The BCL20 offers full control over Threshold,
Ratio, Attack, Release and Gain make up. Each channel has two high resolution
twelve segment LED bargraphs, one to display gain reduction and another which can
be switched to display input or output level. The I/O meter can be switched between
Peak or VU response. A unique feature of the BCL20 is the inclusion of control over the
detection characteristics, which can be mixed between Peak and RMS levels. This
enables the compressor to be made sensitive to high energy transients or to wider
programme modulations. The De-Ess function is activated by means of a single switch
which inserts a slew rate sensitive filter into the side chain to produce frequency conscious
compression in accordance with FM transmission or disc mastering pre-emphasis. A rear
panel jack insert point allows the connection of an external equaliser in the sidechain for other
frequency conscious processing applications. The BCL20 is equipped with high impedance
balanced inputs and transformer balanced outputs on XLRs. The output stage features a unique
Transformer Distortion Cancellation circuit, which reduces transformer distortion to negligible
levels. The BCL20 is manufactured in accordance with directives encompassed within the 'CE'
regulations particularly those concerned with RFI protection.

 Reverbs & Delays

Because it is one of the most desired effects, the FX2000 provides 12 different reverb programs, so you always have the ideal reverb for your live performance or studio needs.

Reverbs include:

    CATHEDRAL
    GOLD PLATE
    SMALL HALL
    ROOM
    STUDIO
    CONCERT
    STUDIO
    STAGE
    SPRING REVERB
    AMBIENCE
    EARLY REFLECTIONS

Specialty reverbs include:

    REVERB – reverb is synthetically turned off after a predetermined amount of time
    REVERSE REVERB – reverb envelope is reversed—it slowly gets louder

Delays include:

    STEREO DELAY – delay is processed across the entire stereo image
    TAPE ECHO – simulates classic tape echo devices, pre-dating the advent of digital delays
    PING PONG – delay signal is "bounced” from left to right at an adjustable tempo

Much More than Just Reverb and Delay

The FX2000 has some of the best-sounding reverb and delay programs, but thatʼs not all. It also provides excellent modulation effects (such as chorus, flanger and phaser), including special variations like musical pitch shifter, tremolo and even a rotary speaker simulation.

Modulation and Pitch Shifter FX:

    STEREO FLANGER (originally generated by playing back two synchronized "reel to reel” tape recorders with a finger rubbing on the flange of one of the take-up reels)
    VINTAGE FLANGER simulates a guitar fl anger stomp box
    JET STREAM FLANGER sounds like a classic analog flanger
    STEREO CHORUS (combines a slightly detuned signal with the original)
    ANALOG CHORUS simulates a guitar chorus stomp box
    VINTAGE CHORUS imitates a classic analog studio chorus
    ULTRA CHORUS creates the sound of an eight person chorus
    STEREO PHASER (combines a second, phaseshifted signal to the original)
    VINTAGE PHASER represents a guitar phaser stomp box
    DUAL PHASER processes the left and right channels separately
    ROTARY (simulation of the rotating speakers typically used on an organ) – Slow or Fast
    PITCH SHIFTER (changes the pitch of the original signal) – can be used to create harmonies with the original signal or replace it entirely with the altered pitch. Choices include stereo, two and three vocal pitch shifter
    VIBRATO – the peak frequency of the tone is periodically and uniformly changed (quickly or slowly)
    TREMOLO (common vintage guitar amplifier effect) – a fast or slow periodic variation in volume
    AUTO PANNING – signal is automatically sent from one side of the stereo image to the other, either once or multiple times

Dynamic FX:

    COMPRESSOR – reduces the dynamic range of the signal, maintains consistent signal level and thus avoids distortion associated with excessive input levels
    EXPANDER – effectively broadens the dynamic range of source signals while reducing background noise
    GATED REVERB – helps reduce background clutter by turning reverb off below a predetermined threshold level. Particularly effective on drum mics and vocals
    ANA. KOMPR/LIM. — similar to COMPRESSOR but with Limiting functionality
    ULTRAMIZER – analyses incoming signal and automatically applies compression across two independent frequency bands
    DENOISER – eliminates or reduces noise and other interference
    DE-ESSER – reduces or removes sibilance (Ssss sound) from signal
    WAVE DESIGNER – allows you to influence the envelope by adjusting Attack and Release of the signal

Psychoacoustic FX:

    EXCITER – adds artificially generated overtones to the original signal, increasing presence and perceived loudness without significant increase in signal level
    ENHANCER – functions much like a dynamic pitch equalizer
    ULTRA BASS – sub-harmonic processor combined with bass exciter and limiter
    STEREO IMAGER – divides the signal into middle and side signals, allowing individual signals to be amplif ed when desired and placed on the stereo image
    ULTRA WIDE – creates a broader stereo image
    BINAURALIZER – also creates a broader stereo image and compensates for crosstalk between both speakers

Filter/EQ FX:

    AUTO FILTER – influences the frequency response of a signal. Two filters are included: low pass allows low frequencies to pass and suppresses high frequency content; high pass does the exact opposite
    LFO FILTER - Controls the rate of oscillation effects
    PARAMETRIC EQ – allows you to control the bandwidth, frequency and amplitude of a signal
    GRAPHIC EQ – the sound spectrum is divided into eight (8) adjacent frequency bands, which can be cut or boosted, bandwidth is predetermined

Distortion FX and Amp Simulations

The FX2000 is also equipped with distortion, amplifier and speaker simulation including VOCAL DISTORTION, TUBE DISTORTION, GUITAR AMP, TRI FUZZ, SPEAKER SIMULATION, RING MODULATOR and LO-FI.

Special FX:

    VINYLIZER – adds clicks and/or noise to the signal, reminiscent of old vinyl records and tape machines
    SAMPLER – allows you to record and playback up to five (5) seconds of program material
    VOCODER – allows the input signal to modulate another signal (usually a synthesizer sound), creating the familiar "talking synthesizer” effect
    VOICE CANCELER – removes mono vocal parts from stereo recordings for "instant Karaoke”
    RESONATOR – simulates and oscillating system that amplifies a specific frequency

Our FX Combinations Go to 11

Sometimes you want to add a little (or a lot) of color to your reverb and delay patches. The FX2000 allows you to layer modulation effects like chorus, flanger, pitch or tremolo with your reverb or delay selections.

FX Combinations include:

    Chorus & Reverb
    Flanger & Reverb
    Leslie & Reverb
    Pitch & Reverb
    Delay & Reverb
    Tremolo & Reverb
    Phaser & Reverb
    Chorus & Delay
    Flanger & Delay
    Pitch & Delay
    Tremolo & Delay

Innovation

The ARX AFTERBURNER? is a unique Multi Mode compressor/limiter
designed for use in any professional audio dynamics control application.
Multiple Modes
The Afterburner can be set up and used in three different ways:
In Two channel mode, it performs as two independent compressor/limiters,
with 'industry standard' variable Threshold, Ratio and Output gain. In stereo
mode, our New Adaptive Stereo Link circuitry provides increased stereo
imaging accuracy when linking both channels as a stereo pair. A single front
panel switch puts the Afterburner into its alternative Mono mode, setting it up
as a Single channel, Dual Band compressor/limiter, with separate dynamics
control of both Low and High frequencies, opening up a whole new range of
gain control techniques.
Enhance Switch
In any mode, the Afterburner features an 'Enhance' switch, which provides
frequency restoration to preserve the spectral balance of the audio signal,
compensating for the sagging Low and High frequency response of compressed
program material. Think of it as a 'smart' loudness control.

In today's recording and sound reinforcement environments, the need for multiple channels of high quality, easy to use compression is growing rapidly. The new dbx® 1046 is designed to provide the audio professional with just that: 4 channels of great sounding dbx compression for a variety of applications. Incorporating the industry standard dbx designs and the latest available manufacturing techniques, the dbx 1046 provides pristine sonic quality with that classic dbx sound.

The 1046 provides 4 channels of smooth classic dbx OverEasy® or Hard Knee compression that are perfectly suited for use on individual tracks of your multitrack recorder, and in virtually all applications the separate channels can be individually interfaced and used for entirely independent purposes. Additionally the newly developed PeakStopPlus™ is ideal for protecting your system from the oppressive peaks that can take out valuable drivers in your sound reinforcement rig or studio monitors.

All four channels have the following controls:

Threshold - allows you to set the level at which the compressor starts affecting the gain

OverEasy - allows you to select between soft compression for overall gain control or Hard Knee compression based on the characteristics of the original dbx 160.

Ratio - allows you to set the slope of gain reduction affecting the signal over the threshold level.

Input/Output Meter - allows you to set the meter to check the input and output levels for maximum signal-to-noise ratio and best level matching.

Output Gain - allows you to add make-up gain or to adjust the output level for that channel to match the next device's input gain.

Bypass - hard wire bypass allows you to hear how the compressor is affecting your signal.

PeakStopPlus - allows you to set the maximum signal level you want to pass through this channel. While it's virtually impossible to eliminate distortion, the PeakStopPlus circuit does it gracefully and effectively with minimal distortion.

Stereo Link - allows you to link channels 1&2 and 3&4 for two channels of true stereo compression.

All four channels feature balanced gold plated XLR and 1/4" inputs and outputs, and switchable +4dBu or -10dBV operating level to interface each individual channel with any other device.

So whether you need to control the level, placement in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx 1046 is for you.

• Four independent channels of operation, stereo linkable in two pairs
• PeakStopPlus™ limiting control for setting maximum allowable level regardless of compressor settings
• Independent Threshold and ratio controls
• Switchable OverEasy® or Hard Knee compression
