Graphic Equalizers - GQX Series

GQX-3102 TWO CHANNEL 31-BAND

GQX-1502 TWO CHANNEL 15-BAND GQX-3101 SINGLE CHANNEL 31-BAND

Ashly’s GQX Series models take advantage of 20 years’ experience with some true advances in technology.

Precision Wein-Bridge filters and specially designed summing amplifiers provide extremely accurate response, low noise, negligible distortion, and excellent immunity to magnetic fields. All filters exhibit true constant “Q” response, with absolute minimum ripple. The full-throw faders are a custom-manufactured metal-shaft type, with the center detented position utilized as an “on/off” switch for that filter (to minimize any possible degradation in signal noise levels). These units continue to meet specifications when voltage drops down to as low as 93VAC, making them the ideal choice when power stability presents a problem to the installer.

The GQX Series is available in three different configurations: the GQX-1502 features two channels of 15-band 2/3octave equalization and a switchable high-pass filter. The

GQX-3101 is a single-channel 31-band model, while the GQX-3102 features two channels of 31-band

1/3-octave EQ. Both the GQX-3101 and GQX-3102 offer tunable high-pass filter circuits and 10-segment, two color LED meter displays, referencing 0 VU to

+4dBu. The GQX-3101 and GQX-3102 features switch-selectable cut or boost of either 6dB or 15dB, and carries the same Five Year Worry-Free Warranty offered on all sound products from Ashly. All GQX models are also U.L. Listed to meet the requirements of permanent installations.

MQX-2150 TWO CHANNEL 15-BAND MQX-1310 SINGLE CHANNEL 31-BAND

At Ashly, we believe that engineers should never have to compromise their standards for the sake of miniaturization.

So we proudly offer the MQX Series equalizers, which feature all the performance and great sound of our legendary GQX models in uniquely compact packages.

The MQX Series uses the same precision filter design and summing circuitry as the GQX Series, with each filter exhibiting true constant “Q” response. The center-detented position of each fader acts as an on/off switch for its filter, ensuring absolutely flat response and high signal-to-noise ratios. The faders themselves put these equalizers into a class all their own. A full 25 mm throw makes use of every last bit of panel space so that small panel size doesn’t compromise resolution. The additional range and incredible accuracy of this fader allow us to offer ±15dB of amplitude adjustment on each individual filter (an Ashly exclusive in this class of product). Housed in a rugged steel chassis, each model features multiple input and output connectors. For engineers looking to avoid those cumbersome “wall warts,” Ashly features internal power supplies on all our products. And, of course, each MQX

Series equalizer is covered by our exclusive Five Year

Worry-Free Warranty.

Parametric Equalizers - PQX Series

PQX-571 SEVEN BAND SINGLE CHANNEL

PQX-572 SEVEN BAND TWO CHANNEL

Ashly Audio was among the first professional audio manufacturers to offer parametric equalizers. Today, our design includes five fully parametric bands per channel, sweepable over the entire audible range of 20Hz to 20kHz. Tunable low and high shelving filters are also provided to equalize frequency extremes. All seven filters have in/out bypass switches, while the use of separate summing amplifiers eliminates filter interaction. The PQX Series offers low noise, great headroom, full 20Hz–20kHz range on all parametric filters, and dynamic range of 112dB with all filters engaged (130dB in bypass mode). Individual filter bypass switching, as well as a master bypass switch, are provided for easy setup. Bandwidth adjustment ranges from 3.3 octaves to 1/20th of an octave for very selective filtering of problem frequencies. The single-channel PQX-

571 offers a total of seven bands of equalization—five fully parametric filters, as well as tunable low- and high-frequency shelving. The PQX-572 is a stereo or dual-channel model with the same features on each channel. Each is covered by our exclusive 5-year, Worry-Free warranty.

FEATURES:

• 5 Fully Parametric Bands

• Parametric Filters Tunable from 20Hz–20kHz

• Tunable Low and High Frequency Shelving Filters

Crossovers - XR Series

XR-1001 STEREO 2-WAY, MONO 3-WAY

XR-2001 SREREO 3-WAY, MONO 4/5-WAY XR-4001 STEREO 4-WAY

The XR Series II crossover feature 24dB per octave filters, infinitely variable crossover frequency and response, as well as both 1/4” TRS phone jacks and XLR connectors for all inputs and outputs. Output Mute switches on each channel are included for convenient and accurate setup operation, and a peak overload indicator monitors all critical points in the circuit to ensure low-distortion operation. A recessed switch on the front panel with an LED indicator allows for either normal or “divide by ten” frequency selection.

The XR Series II models feature Ashly’s exclusive

“Response” control, allowing the user to select the best performance for a given application. The purpose of this control is to help offset the inaccuracies inherent in typical loudspeakers, where many anomalies can occur at the crossover point. This Response control adjusts the damping of the filter, affecting its shape near the crossover point. The “Butterworth” response, for instance, results in a gentle 3dB rise when the two filter output signals are combined. Similarly, a “6dB” setting produces a “Linkwitz-Riley” response for flat summing. Other responses are possible to correct for driver, cabinet, and room problems at the crossover point. No other crossover offers the ability to dynamically shape filter response as precisely. For the ultimate in sound system control and accuracy, the

XR Series II models are the logical choice.

The XR-1001 is a stereo two-way or mono three-way crossover. The XR-2001 offers the unique ability to operate as a stereo three-way or mono four- (or five-) way, or even as a four-channel two-way configuration for bi-amplifying onstage monitor systems. The XR-4001 fulfills the needs of four-way stereo setups. All Ashly crossovers are U.L. Listed and backed by our exclusive Five Year Worry-Free Warranty.

FEATURES:

• 24dB Per Octave Slopes

Signal Processors

CLX-51 SINGLE CHANNEL COMPRESSOR/LIMITER

CLX-52 DUAL CHANNEL COMPRESSOR/LIMITER

The CLX Series compressor/limiters use an “infinite softknee” characteristic and timing based on compression ratio. This, combined with a dual release time, allows program density to increase as the input signal increases.

The result is a peak controller with very low noise, smooth sound, and excellent stereo tracking without the usual

“constricted” limiter sound. Ashly’s CLX series uses peak rather than RMS limiters. While an RMS limiter may be used to restrict material to a given loudness, a peak limiter looks at the maximum voltage a signal reaches regardless of its waveform, making it the right choice to prevent clipping, overmodulation or tape saturation.

The CLX-51 and CLX-52 have many ways to deal with any gain structure. The mechanical design is ready for years of rugged service and we back our quality with Ashly’s exclusive Five Year Worry-Free Warranty.

The CLX series is extremely useful for such diverse applications as loudspeaker protection, vocal level control, broadcast limiting, musical instrument sustain, special effects, and CD to cassette transfers.

FEATURES:

• Extremely low noise and distortion

• Dual release time for minimum “pumping”

• Wide-range control of all parameters

• Powerful peak control with minimum audible side effects

• Both XLR and 1/4” input and output connectors

DPX-100 GRAPHIC EQUALIZER & COMPRESSOR DPX-200 PARAMETRIC EQUALIZER & COMPRESSOR

The DPX Series was created to provide a simple solution for systems requiring general EQ and comp/limiting. Two products are available, the DPX-100 Graphic Equalizer &

Compressor/Limiter and DPX-200 Parametric Equalizer &

Compressor/Limiter. The equalizer section and compressor/ limiter may be used independently or chained together in series. Audio connections are balanced XLR and ¼” TRS.

Using proven circuitry from our popular MQX and PQX series equalizers and combining these features with our

CLX series compressor/limiters provides two tools no audio system should be without. By combining the features and benefits of two processors into one unit, the result is two powerful tools providing a simple solution to everyday audio applications.

The EQ section of the DPX-100 is a 15-band, constant Q,

2/3 octave, ISO center, precision wein bridge filter design.

Other EQ features are: frequency range from 25Hz to

16KHz, selectable 15dB or 6dB range, 25mm faders with

‘center off’ position, EQ in/out switch, signal present and clip LEDs and switchable 18dB/octave -20Hz high pass filter.

Two separate inputs are available in the DPX-200; a microphone preamp with input pad and a line input. The EQ section consists of 4 bands of filtering; two full-bandwidth parametric EQs as well as a low-shelf and high-shelf filter.

Other EQ features are: in/out switching for each filter, cut and boost of 15dB, signal present and clip LEDs, and master EQ level control.

The compressor/limiter section uses peak detection circuitry and has individual controls for gain, threshold, ratio, attack, release and output level. More compressor/limiter features include: in/out switch, 11-stage LED gain reduction meter, selectable 11-stage LED input/output level meter, and a detector patch point for frequency-selective limiting or ducking.

VCM-88 VCA MATRIXNG LEVEL CONTROLLER

RD-8, RW-8 REMOTE CONTROL RD-8 RACKMOUNT

The VCM-88 provides eight fully-independent VCA channels in a single rack unit capable of limiting, remote level control, and mixing. It is designed for installations such as houses of worship, boardrooms, nightclubs, or any place remote control of individual levels is required. By itself, the VCM-88 functions as a precise eight-channel limiter with recessed threshold adjustments on each channel.

Control is accomplished by Ashly’s RD-8 or RW-8 remote controllers, RS-232 control using Ashly’s Protea System Software,

Crestron or AMX touchscreen controllers, MIDI, or DC control using external potentiometers.

When connected to the Ashly RD-8 Remote Controller or DC control, the VCM-88 adjusts individual channel and master levels with a range of -75dB to +20dB. Each VCA channel has separate input and output jacks for patching into linelevel signal paths, and can be reconfigured to use single jack TRS insertion for patching into mixing consoles. In addition to setting and controlling the VCM-88 from the front panel, a dedicated RS-232 computer interface and full MIDI implementation is also provided.

Internal switching allows you to patch channels for signal routing and matrixing and select channel pass-through for cascading multiple units in parallel. The VCM-88 also has a master output jack providing a summed output of all channels, allowing the unit to function as a fully-contained eightchannel remote controlled line-level mixer.
