An exceptionally intuitive front panel, with integral LCD menu (using graphical icons similar to those used on many smartphones) makes operation of the Intelli-X² extremely quick to learn. Critical attention has been focussed on synchronisation. Four sync options are available: Wordclock, AES A/B, AES C/D and internal. The Intelli-X² series manages synchronisation by providing a three-tiered redundancy approach, ensuring that if any sync source is lost, the Intelli-X² will automatically revert to another (as defined by the user) ensuring no loss in audio.

An integral date and time-based logging system is incorporated within all Intelli-devices. The log provides details of any key configuration/ control changes made and this log is available for viewing on the front panel display, or can be downloaded directly onto a computer. The Intelli-series is designed to interface easily into any existing (or bespoke) Ethernet network via internal 3-way Ethernet switches. Both automatic IP (DHCP) and static IP configuration is provided as standard, enabling plug & play connectivity and more rigid IP assignments for use in fixed installations.

Noise level control systems The Apex SL-Series is a set of tools to protect hearing, neighbours, the environment and equipment against excessive sound levels; all without altering the quality of the material. The concept behind the SL-Series is to have two basic units, the Argos and the Hera. These can be used independently or combined to provide a fully featured sound levelling system.



Argos sound



You may need to comply to local regulations in matters of sound levels, or you simply wish to have a responsible attitude towards your customers’ hearing. Alternatively you may wish to protect your speaker system from abuse, or maybe you wish to do all of the above. Either way you’ld like to offer your customers great sounding music without damaging their hearing. The Apex Argos sound level limiter is regularly stated by the press and by our customers as the most natural sounding and smoothest level limiter available. Argos will prevent your sound system from producing excessive sound levels, while perfectly preserving the dynamic range of the original signal by acting as a real gain control. Precise threshold overshoots are permissible as the Argos operates within the required equivalent continuous sound level (LEQ) range. 14


Features • unique servo-loop circuit allowing smooth operation (resulting in no compression or limiting artefacts) • stated as the most natural sounding leveller • unique silence detection function with gain reduction hold circuit (avoiding pumping effect when audio returns after a silence), ideal for live bands • 3 sound level detection modes: microphone, line or loudspeaker • direct connection to power amplifier output and fast operation mode allowing use as a speaker protection system

• may work independently or combined with the Apex Hera to increase functions and capabilities • choose between smooth and fast operation • sound level and gain reduction indicators • concealed and authority sealable configuration panel • the ‘Test’ button on front panel confirms correct installation • choice between A-weighted and C-weighted filters • built-in pink noise generator for calibration • balanced 3-pin XLR and RCA (cinch) connectors at inputs and outputs



Hera s o u n d l e v e l c o n t r o l l e r

The Apex Hera is a microprocessor based sound level controller. Hera can be used either as a separate unit or combined with the Apex Argos. Hera will not only log the average (Leq) and peak RMS sound pressure levels over time, but also detect and log any attempt to disable the system. The files can be easily consulted by any user directly from the front panel or retrieved on a computer and printed out. Hera also offers two logic outputs that may be used to drive relays for signalisation or mains cut-off if a certain threshold is being exceeded. All settings are pin code protected and can easily be entered from the devices’ front panel. COMBINED WITH THE ARGOS, UNITS WILL ACT AS THE ULTIMATE SOUND LEVEL (NOISE CONTROL) SYSTEM, WITH MEASUREMENT AND LOGGING FUNCTIONALITY 16


Hera log read-out Viewing the events and measurements log from Hera’s memory is possible using a standard serial cable connected to a PC. Extending this application through a network or the internet is also a straightforward process that only requires the use of an inexpensive Serial-to-Ethernet converter. The software necessary to view the Hera log is freely available on Apex website.

Features • factory calibrated for accurate measurement • all settings may be made from the front panel and are pin-code protected • two separated logic outputs for controlling external devices and mains power cut relays, all set/reset times are adjustable • average and peak RMS sound level logging over an user adjustable time frame • system tamper detection and logging • 14-days sound level log (when measurements are logged at 15 minute intervals) • ability to schedule multiple threshold parameters covering any time or day of the week • easy computer log read-out through standard serial port

dual active direct-injection box


The dBDI-2 two channels active DI box combines Apex audio performance with versatility. The dBDI-2 is just as at home in a studio or multi-media facility as it is in clubs and on-the-road.

High quality transformers, shielded within mu-metal cans, provide each channel with a galvanically isolated and balanced output; ensuring that audio integrity and performance is at its best.

With the dBDI-2 you won’t find yourself in a fix with incompatible connector types. Each channel provides XLR (3-pin), ¼” jack and RCA (cinch) input connectivity as standard, you can take the dBDI-2 anywhere. Capable of accepting a wide range of input signals (from guitar or bass pick-up to high level amplifier output) the dBDI-2 can be configured to meet the most demanding of applications. Dual mono, or stereo operation is catered for, while enhanced features enable channel inputs on the dBDI-2 to be summed together or even allow the dBDI-2 to be used as an active splitter.

Channels on the dBDI-2 can be individually powered with separate 48 V phantom supplies, or via an external power adapter. The rugged aluminium extruded standalone design conveniently allows cables to be run underneath the dBDI-2, while the rubberised end cheeks provide both additional protection and enable multiple units to be stacked in a safe and secure manner.


For those who require a rack based solution, two dBDI-2 devices can be mounted onto a single 1U optional 19” rack panel.

Using the dBDI-2 in this way allows 4 comprehensive direct inject channels with all input and output connections accessible from the front panel to be available as a single unit. This is ideal for keyboard racks, guitar rigs,...

Features • Reliable, high performance active two channel direct inject box • Rugged easily stackable enclosure • Ideal for tour sound, multi-media, clubs and fixed installations • Comprehensive connectivity as standard • Low distortion design • Transformer output design eliminates ground loops • Power connector for external AC adapter • Dual mono or stereo operation with channel sum facility • Active channel splitter • Kensington® security slot • Optional rack-mount panel



dBZ-48 stereo distribution mixer

The versatility and performance of the dBZ-48 makes it an ideal solution for fixed installations, live sound, multi-media and broadcast applications. Housed in a 1U 19� rack enclosure, the dBZ-48 features two stereo analogue inputs and four stereo analogue outputs. Each stereo input provides clear and precise LED metering, and Mute, Mono Sum and gain adjustment facilities. Similarly, each stereo output section comes fitted with identical features, with the addition of independent mix controls for both stereo inputs, allowing unique stereo mixes to be sent to each output. For security purposes, an optional front panel guard is available to prevent anyone from tampering with the dBZ-48 controls. The dBZ-48 provides the versatility to be employed in many situations. 24


Applications Zone Mixer: The dBZ-48 allows installers to mix two stereo sources (for example, a multi-disc CD player and a hard disk based playout device) to four separate zone outputs. The four stereo outputs can then be wired to active speakers, amplifiers or speaker management systems in each zone. Stereo Distribution Amplifier: It is now a common requirement to distribute a single stereo source to multiple destinations, whether they be to rooms in an installation or theatre, to FOH and Monitor consoles or for dedicated broadcast or recording feeds. The dBZ-48 comfortably provides this functionality in a way that is simple, effective and quick to configure.

Features Stereo Merge: In many situations there is a requirement to merge multiple stereo sources. It may be the case that in a live environment the output of two FOH consoles need to be merged together. Alternatively there may be a requirement to free channel resources on a FOH console by removing any CD or hard disk playout device. The solution is to mix these sources together within the dBZ-48. By using the dBZ-48 the process is quick and efficient.

• Professional quality and reliability • Mute control for each input and output section • Mono sum for each input and output section • Comprehensive LED metering, with Clip indication • Electronically balanced inputs and outputs (Neutrik® XLR connectors throughout) • RF filtering on audio I/O and mains supply • Universal switch-mode power supply • Optional front panel guard for security



dBZ -48d stereo distribution mixer with delay and EQ

Applications The dBZ-48d comes fitted with identical features as from the dBZ-48. Its uniqueness comes in the form of digital signal processing (DSP) within the device. Each output features user-selectable delay, 24dB/Octave high and low pass filters and polarity control, making the dBZ-48d an ideal solution for system designers looking to mix and distribute stereo sources to multiple destinations. All DSP parameters are adjustable from the front panel via a comprehensive set of controls and a clear alphanumeric display. The dBZ-48d also offers eight memory presets enabling configurations to be stored and recalled from the front panel. An ideal feature for touring applications or multi-purpose venues.



Zone Mixer: More than a standard zone mixer, the dBZ-48d offers both high-pass and low-pass filters per stereo output channel. The ability to add and control these filters within installs, such as restaurants or bars, can help enhance the overall ambience for clients wishing to talk, by limiting the bandwidth of the background music. In addition, by filtering unwanted frequencies from reaching small form-factor speakers, such as ceiling speakers, improved intelligibility and speaker protection can be achieved. Implementing such filters can also remove the need for using external crossovers on sub-woofers. Stereo Distribution Amp: Time alignment has never been so straight forward. Setting delays for under balcony speakers or delay towers can now be performed quickly and efficiently.

In large venues or open-air areas it is important to make use of multiple speaker positions in order to maintain coverage. Delays are required to align the overall system and eliminate the ‘echo effect’ caused when speakers are set some distance apart. Implementing the delays accurately within the dBZ-48d can therefore result improve intelligibility. Delay adjustment is made even simpler by displaying values in distance or time (user selectable) in a smooth and glitchfree manner.

Video application: With today’s increasing demand to integrate video into the live sound environment (such as concerts, V-DJs etc.) the issue of synchronising audio to video may well pose a challenge. The dBZ-48d is the ideal solution as it enables delays to be inserted at frame resolutions (24, 25 and 30-fps) across each output.

Powered loudspeaker partner: In many live applications (such as conferences, product launches, diners and talk-shows) powered loudspeakers can prove to be very convenient. The dBZ-48d ensures that signal distribution, time alignment and crossover functionality (if required) are all provided within a single unit to four separate stereo or mono zones. dB-Series


dBQ-Zero 2x30 band graphic equaliser

The new improved version of the dBQ-zero features the 30-band constant-Q graphic section on each channel, plus a filter section consisting of a high-pass filter, high and low shelving equalisers and two notch filters. Shelving filters add warmth and colour to the mix. A typical application for our frequency adjustable high-pass filter is to remove hum or vibration transmitted by turntables. Notch filters allow fast and easy removal of noise or potential feedback frequencies. Interchannel crosstalk and THD+N figures are improved, as his load stability with the implementation of the updated line driver circuitry. 28


Constant-Q design preserves filter bandwidth independently from the amplitude control settings and therefore minimises the adjacent band interaction. Constant-Q reinforces the graphical representation by the front panel faders of the actual frequency response. Changes have also been made to the chassis and cosmetics of the unit, resulting in improved ruggedness and an intuitive user interface. Two 10-segment LED level indicators, each with dedicated signal and clip LED, monitors the signal level.

Features To simplify set-up whether, on the road or in a fixed installation, the dBQ-Zero offers XLR, 1/4” Jack and screw terminals connections, all electronically balanced. Bypass relays are also provided in the event of loss of power. A must have in any outboard rack !
