THE CLR SERIES is a range of professional, reference quality loudspeakers from, Atomic Amplifiers, the world’s first and leading company designing amplification and monitoring solutions for amp modelers / profilers. The current offering includes both CAB and

WEDGE formats that come in active and passive versions.

Products in the CLR Series are designed and built with the performing or studio guitarist in mind, but are also extremely effective for acoustic guitars, vocals, keyboards and other electronic instruments, and any other application where a FRFR system is needed.

The CLR Series represents a highly accurate and superior-sounding solution for the modern digital guitar rig. They ensure that preamps, modelers, profilers and simulators will sound their very best by producing reference-quality sonic transparency at rock

SPLs in the most difficult acoustic environments. Even as guitar tone processing technology advances, the CLR Series products will remain a viable and valuable investment in tone.

The CLR Series is engineered to withstand the demanding conditions of life on the road or in other professional environments, whether on stage, in the studio, or in a standalone setting.

S Y S T E M D E S C R I P T I O N

The Atomic CLR is a two-way coincident loudspeaker consisting of a heavy-duty, horn-loaded 12” cone transducer for low frequencies and a high-output, 1”-exit compression driver with a 1.75” voice coil driving a constant-directivity type horn for high frequencies. The enclosure is constructed of 12-ply, void-free plywood throughout, with internal structural details that serve both to form the lowfrequency horn shape and to add substantial structural rigidity.

Non-powered versions of the CLR incorporate a heavy-duty passive crossover designed to optimize amplitude response and preserve the integrity of transient signals. Powered versions include two independent channels of power amplification - one each for low and high frequencies - and a line-level active crossover that employs digital signal processing. The power amplifier topology is a patented, high-performance variation on Class D that has found use in a number of expensive, audiophile-quality loudspeakers.

The DSP filtering is designed to optimize both amplitude and transient response and is equipped with special features designed to minimize the chances of driver damage due to operation at excessive levels.

Active CLRs provide user-selectable presets for three common acoustic boundary conditions: free-field, tilt, and backline. The freefield setting is optimized for use when the speaker is elevated off the floor on a pole or stand; the tilt setting is optimized for use as a floor wedge, with the speaker on the floor aimed up at the player; and the backline setting is optimized for placement of the speaker on the floor and aimed horizontally, as is common for guitar amp usage. There is also a switchable 120-Hz highpass filter for use with a subwoofer or for removal of unwanted low frequencies.

Refer to the panel diagram for more features.

ACTIvE CAb AND WEDgE PANEL ExPLANATIONS

1. Heat Sink – Allows the CLR Series to be fanless and “studio quiet”. It keeps amp modules and power supply cool by drawing heat from them and dissipating it into the open air. Please note: The heat sink will get warm to the touch while the amp is powered “on” even when the amp is at idle. This is normal and is well within regulated operating guidelines.

5. Preset Switch – Adjusts the frequency response of the amplifier to accommodate 3 different cabinet orientations while maintaining a flat response. The presets are: “FF” = Free Field – for when the cabinets are elevated off the floor like on a chair, pole mount or stand, “Tilt” – for when the cabinet is set up in the wedge position on the floor and “BL”

– for when the cabinet is set up like a traditional guitar setup on the floor.

6. Speaker Limit Indicator – Flashes red when speaker is approaching it’s operating limit. An internal safety function stops the amp from driving the speaker harder. Please note: The speaker limit indicator will flash in advance of the threshold. Only when it is nearly constantly lit red will the safety function come into play.

8. Sub – When in the “on” position this switch attenuate the low end of the system to accommodate use with an external sub woofer.

1 Link Select – Selects what inputs get sent to the Link Output – “1”

Input 1, “2” Input 2 and “X” a mix of Input 1 and 2. The level controls only come into play in “X” or Mix mode otherwise it sends through unity gain from the selected channel.

1 Link Output - A pre eq, buffered pass through that takes signal directly from the analog front end to wherever you need to send it.

1 IEC Power Inlet - Connect the supplied AC line cord to provide power to the amp.

2. Thru – ¼” / Speakon Combo pass though to send signal to another system.

gAIN STRUCTURE SETUP fOR ACTIvE SPEAkERS

Optimizing gain structure is an important step in minimizing noise and preventing signal overload (clipping). There are three level controls on the panel of active CLR speakers. After connecting all the devices in your signal chain and powering up (remember CLR last on, first off), follow the procedure below to insure optimal gain structure.

1. Set the Master and both Input level controls to their lowest

(CCW) settings.

2. If you will be using two input signals, perform this step with the one you expect to be louder. (Note: You will hear little or no sound during this step.) Apply the hottest (loudest) signal you expect to generate.

Increase the Input level control for that channel until you see the LED adjacent to that input connector light up. Turn down the level until the

LED goes out and never lights.

3. Adjust the Master level for the desired volume and the second Input level (if used) for the desired mix. There is no need to adjust the

Input levels beyond this point. The amp has the ability to reach its maximum output level with the input level set as prescribed above.

Overdriving the input by setting the input level too high will result in audible clipping.

PASSIvE CAb AND WEDgE OPERATINg INSTRUCTIONS

Passive CLRs are equipped with two combo connectors (Neutrik Speakon and 1/4” jack). These connectors are wired in parallel and are intended to enable the user to “daisy chain” a second CLR to a single power amplifier. Keep in mind that the combined impedance of two CLRs in this configuration is 4 ohms and make certain that the power amplifier is rated to drive this impedance. Caution: under no circumstances should the additional connector ever be connected to a second power amplifier.

Doing so could result in damage to one or both power amplifiers and to the speaker(s).
