TRANSFORMER circuit completed the final piece of the puzzle and again involved many rounds of fine-tuning to settle on the design. But we didn’t just design Fusion in the isolation of SSL HQ; when the first prototypes were complete we sent them off to a selection of trusted engineers and made further adjustments to the circuits based on their feedback.

Introduction Fusion is an all-analogue stereo outboard processor created for the hybrid studio. Fusion introduces five completely new analogue colouration tools designed to bring the perfect combination of added tonal character, clarity and depth to your mix bus or stereo stems with the detail, warmth and finesse that only real analogue circuits can provide.
Rack Mounting, Heat & Ventilation Fusion is a 2U, 19” rackmount piece of equipment designed to sit in the racking of a producer’s desk or similar. Fusion’s no compromise design is powered by a toroidal transformer and as such, the left-hand side of the unit can become warm to the touch.

Alternative Setup Option If you do not use the hardware insert functionality in your DAW, you can use the following method to integrate Fusion into your setup: Choose a pair of analogue inputs and outputs that are not being used on your audio interface e.g. outputs 3 & 4 and inputs 1 &...
Connecting Fusion to an Analogue Desk / Summing Mixer Fusion is the ideal analogue processor to complement your analogue summing system. The example below shows how to connect Fusion and an SSL Bus Compressor to your analogue desk or summing mixer.
Fusion. Remember, a number of Fusion’s circuits are level-dependent and this will affect the sound you get. Depending on how loud or quiet your mix already is, you may need to start by adjusting the INPUT TRIM in order to achieve the best possible gain-staging.
Left and Right Overload LEDs light red if the signal at Fusion’s input exceeds +27dBu. Input Trim The INPUT TRIM provides ±12dB gain at the input stage of Fusion. This pot is indented at the 12 o’clock position. You should use this control to achieve the best gain-staging through Fusion. Try starting with the pot at the indented 0 dB position if you are at the beginning of a the mixing process.
The 5 Colour Circuits The descriptions that follow cover each of Fusion’s 5 colouration circuits. Each circuit has an associated IN switch which allows you to switch that particular circuit in or out. When a circuit is on it turns orange. When bypassed, the switch is backlit a soft white colour.

Stereo Image The STEREO IMAGE circuit allows for true mid-side processing within Fusion. Mid-Side is a technique commonly used in mastering that separates a stereo signal into 2 channels - one for the sounds in the centre (mid) of a stereo image and the other for the sounds on the edges of the stereo image (side).
‘weight’ to the sound. It is worth noting that the drive of the transformer circuit is self-contained, so there is no advantage in driving the Input stage of Fusion to achieve more level through the transformer.
The BYPASS switch allows you to bypass all of Fusion’s processing blocks. If the BYPASS switch is red, then you are in standard BYPASS mode. Use this to compare the sound of the mix with/without Fusion in one easy action. It dimly lights white if you are not in bypass.
FRONT PANEL SWITCHES The switches used in Fusion are solid state switches that trigger a single relay for audible feedback. The benefit of this approach is that it allows for the front panel switches to be repurposed for additional functions, such as settings and secondary switch modes (M/S mode on the Insert Switch for example).
Settings Mode & Factory Reset Settings Mode & Factory Reset This section will detail how to enter Fusion's Settings Mode and the functionality that can be changed. It also details how to reset Fusion back to a factory default state.
Settings Mode & Factory Reset Factory Reset To reset Fusion to factory settings, switch the unit on then hold down the VINTAGE DRIVE IN and BYPASS switches during the startup LED sequence. VINTAGE DRIVE Factory Reset allows reset of any stored settings (Brightness, Relay feedback, BYPASS and INSERT configurations) to the factory default.

When servicing disconnect all power sources before removing any panels. CE Certification Fusion is CE compliant. Note that any cables supplied with SSL equipment may be fitted with ferrite rings at each end. This is to comply with the current regulations and these ferrites should not be removed.

Appendix E - Selecting Mains Voltage Fusion has a linear power supply and therefore needs to be manually switched to operate with either a 230V or 115V power suppy. The AC mains fuse is located on the rear panel next to the AC 115V mains connector.
Re-orientate the fuse cartridge 180 degrees and reposition it so that the alternate operating voltage value is displayed through the slot in the fastening. Re-seal the fastening, reconnect the IEC power cable, and switch the unit on. Fusion User Guide...
