Page 3: Introduction
1. INTRODUCTION Congratulations on purchasing the Ivory 5013 Dual Valve Equaliser by TL Audio! The T L Audio Ivory 2 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. -

compensate by turning down the output gain. Alternatively the input gain can be kept low for a cleaner sound and the output gain can be turned up to compensate. This way a wide range of tonal colours is achievable. The line output is via balanced XLR socket at a nominal level of +4dBu, with an unbalanced output on 0.25”... -
Page 5: Installation
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. -
Page 6: Balanced Line Input
The 5013 may be used to shift operating levels, for example by connecting the unbalanced output of a semi-pro mixing console to the equaliser’s unbalanced input, and taking the balanced output of the equaliser to the balanced input of a tape machine at +4dBu. All line-level inputs and outputs of the equaliser may be used simultaneously if required. -
Page 7: Instrument Input
Instrument Input. A 2 pin (mono) jack plug is required, which should be wired as follows: - Tip = Signal Phase (“+” or “hot”). - Screen = Ground. The instrument 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. - Page 8 FIG 2: FRONT PANEL OUTPUT LEVEL CONTROL INPUT GAIN CONTROL EQ BYPASS SWITCH 5013 INPUT INSTRUMENT OUTPUT (PULL) (PULL) DRIVE PEAK DUAL VALVE IVORY EQUALISER INPUT INSTRUMENT OUTPUT (PULL) (PULL) DRIVE PEAK POWER INSTRUMENT INPUT SHELVING SWITCH Q CONTROL MAINS POWER SWITCH (BY PULLING OUT Q CONTROL) FREQUENCY CONTROL ‘FAT’...

The rear panel connectors are identified in Fig.3. Make sure that all settings, mains and audio connections have been made as described above before attempting to operate the equipment. OPERATION Front Panel. The front panel controls are identified in Fig.2. Line Input. - Page 10 Drive LED has reached its full intensity. However, it is possible to add gain further down the chain (EQ boost or output level gain), which will cause the Peak LED to illuminate at a lower level of Drive. This situation implies that a high level of “clean”...

Equalisation. Before switching the EQ into circuit, it is advisable to set the cut/boost controls to their centre, or flat, position. Each channel of EQ is brought into circuit with the overall “EQ-ON” push switch positioned to the far right of the unit. “EQ- ON”... -

band of frequencies either side of the selected centre frequency is affected by any cut or boost actions, while a wide bandwidth (low Q) affects a much broader band of frequencies. As a result, high Q settings (about 5 at the maximum setting on the 5013) are generally used for audio correction or effects - for instance when a single troublesome frequency needs to be removed without upsetting the rest of the frequency spectrum, or a single frequency needs to be boosted to create a... -

modulation. Note that applying additional gain at the output will not increase the dynamic range of the signal, but will increase the noise level as well as the audio signal being recorded, and should therefore only be used if an output level in excess of the nominal +4dBu is required. - Page 14 4. With each EQ band set ‘flat’ (i.e. no cut or boost applied to any band) activate the EQ-ON switch. Starting with any band you can then familiarise yourself with the three controls: Gain, Frequency and Q. Section 4.8 outlines a common technique of identifying frequencies, and with the Q control at its narrowest the effect of each band will be most pronounced.
