In the event of a fault during the warranty period the unit must be returned to your local distributor who will arrange for it to be shipped to Solid State Logic for repair. All units should be shipped to Solid State Logic in their original packaging.
Safety Earth Connection Any mains powered item of Solid State Logic equipment that is supplied with a 3-core mains lead (whether connectorised or not) should always have the earth wire connected to the mains supply ground. This is the safety earth and grounds the exposed metal parts of the racks and cases and should not be removed for any reason.
Mains Supply and Phases Solid State Logic equipment is designed for connection to a single phase supply with the Neutral conductor at earth potential – category TN – and is fitted with a protective fuse in the Live conductor only. It is not designed for use with Phase (Live) and Neutral connections reversed or where the Neutral conductor is not at earth potential (TT or IT supplies).
XLogic E Signature™ Channel Owner’s Manual 3.0 Installation Voltage Selection Before connecting the mains supply ensure that the voltage range selector next to the IEC socket on the rear of the unit is correctly set. The input setting must be confirmed before applying power. The input module can be configured to be one of 4 voltage settings (one of which is invalid and should not be used –...
Mounting This unit is designed to be rack-mounted. It is 1 RU (44.5mm/1.75 inch) high, its depth is: 325 mm/12.8 inches not including heatsink. 365 mm/14.3 inches including heatsink 400 mm/15.75 inches including connectors The XLogic E Signature Channel units incorporate reinforcement brackets into the chassis and so are suitable for direct rack-mounting.

4.0 Operation The XLogic E Signature Channel unit is a 1U rack mounting unit containing a complete set of signal processing based upon the SL 4000 E Series channel strip – Input, Compressor/Limiter, Expander/Gate, Hi and Lo pass Filters and Equaliser. The signal processing order can be changed and the EQ and Filter sections used in the Dynamics side chain.
XLogic E Signature™ Channel Owner’s Manual Dynamics Section The Dynamics section of the XLogic E Signature Channel unit comprises a compressor/limiter and an expander/gate, both of which use the same gain change element. The design returns faithfully to the circuit and key components which defined the sound of the original E Series channel strip. A true RMS converter is used in the side chain whilst the gain element is an all discrete design identical to the Class A VCA chip used in the original unit.
Expander/Gate The Expander/Gate section can ∞ act either as a :1 Gate or, when the EXP switch is pressed, as a 2:1 Expander. RANGE – Determines the depth of gating or expansion. When turned fully anti-clockwise, the Expander/Gate section will be inactive.
XLogic E Signature™ Channel Owner’s Manual Equaliser Section The XLogic E Signature Channel unit equaliser section defaults to the original ‘Brown Knob’ circuit that was standard on all early production E Series consoles. The two parametric mid-band sections feature SSL’s classic logarithmically symmetric design that ensures that the ±3dB up/down points retain the same musical interval from the centre frequency regardless of frequency and amplitude settings.
5.0 Signal Routing Channel Processing Order There are two switches that control the order of the signal processing elements. These are Filters to INPUT and Dynamics PRE EQ. The table below shows the effect of these: Filters Side Chain Processing Order The EQ and Filter sections can be assigned to the dynamics side chain using the DYN S/CH switches in the respective sections.

Appendix A – Internal Links and Fuses Fuses (Mains Inlet) The mains inlet contains a single 1 amp 1.25" time delay fuse (SSL Part No. 35FJJ310). To change it disconnect the mains inlet, then using a small screwdriver prise open the mains selector cover (see illustration on page 6.). Under this cover is a removable carrier that contains the fuse –...

Equaliser This is a four band equaliser that can be switched between two different sets of curves; one based on SSL’s ‘02’ (‘Brown Knob’) EQ and the other based on the latest version of the classic ‘242’ E Series (‘Black Knob’) EQ. High and low pass filters are also available.

XLogic E Signature™ Channel Owner’s Manual Dynamics The unit contains a complete dynamics section, the functions of which split into two areas; a Compressor/Limiter and an Expander/Gate. Compressor/Limiter Controls: Ratio (slope) Threshold Attack Slope Attack Time Release Release Slope The Compressor/Limiter has two different attack slope modes and two different release slope modes; ‘Hard Knee’...
Appendix D - Calibration Information The XLogic E Signature Channel unit is factory calibrated and should only need calibration if a potentiometer or other component has been replaced or if it is suspected that there is a problem with calibration. In all of the following instructions it is assumed that the lid has been removed and that power has been applied.
XLogic E Signature™ Channel Owner’s Manual Meter Calibration Equipment Required: Test Signal: Input and Output: Unit Setup: 1. Set both Line Gain and Output Gain to indent (0dB). 2. Check for +24dBu output level. Adjustment: 1. Adjust VR24 until the ‘+24’ meter LED is just illuminated. 2.
