INTRODUCTION The T L Audio Ivory Series consists of a range of hybrid valve signal processors, which utilise low noise solid state electronics in conjunction with classic valve circuitry to produce audio processing units offering very high quality signal paths with the unique valve audio character. The Ivory Series units offer comprehensive control facilities, whilst remaining straight-forward to operate, and represent excellent value for money.

PRECAUTIONS The T L Audio EQ-5013 Equaliser requires very little installation, but like all electrical equipment, care must be taken to ensure reliable, safe operation. The following points should always be observed: - All mains wiring should be installed and checked by a qualified electrician, - Ensure the correct operating voltage is selected on the rear panel before connecting to the mains supply,...

INSTALLATION AC Mains Supply. The unit is fitted with an internationally approved 3 pin IEC connector. A mating socket with power cord is provided with the unit, wired as follows: Brown: Live. Blue: Neutral. Green/Yellow: Earth (Ground). All mains wiring should be performed by a qualified electrician with all power switched off, and the earth connection must be used.

the best headroom and noise rejection, but can only be used if the other equipment in the chain, e.g. the mixing console, also has provision for balanced connections. Audio Inputs. Line Input. The line level input is via a 3 pin female XLR connector, suitable for balanced or unbalanced line sources at a nominal level of +4dBu.

Auxiliary Instrument Inputs. A 2 pin (mono) jack plug is required, which should be wired as follows: - Tip = Signal Phase (“+” or “hot”). - Screen = Ground. The auxiliary input is suitable for direct connection of instruments including guitars and keyboards. Good quality screened cable should be used, particularly for microphone or low level sources, to prevent hum or noise pickup.

Equalisation. Before switching the EQ into circuit, it is advisable to set the cut/boost controls to their centre, or flat, position. The EQ is brought into circuit with the overall “EQ-IN” push switch, signalled by a green LED. Both channels feature four bands of equalisation, all with fully variable cut and boost controls offering +/- 15dB of range, swept frequency and variable Q.
