User manual XTA E2

[. . . ] A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wider blade and the third prong are provided for your safety. When the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] Gain control: Adjust the amout of cut or obbst of the selected band of frequencies. Note the asymmetric nature of the control ­ 25dB of cut is available, and 15dB of boost. Frequency Control: In conjunction with the range key, select the centre frequency of the band. In shelf mode, this sets the corner frequency of the shelf. Range Key: Scale the frequency range available on the frequency control with this key. The left hand LED illuminated means multiply the values by 0. 1, so the control covers 10Hz to 200Hz. No LEDs illuminated means the range is "x 1" so the control covers 100Hz to 2kHz. The right hand LED means multiply the values by 10, covering the range 1kHz to 20kHz. Shelf Key: Bands 1 & 4 can have their response switched from a parametric (bell) filter to a shelving response. Band 1 will become a low shelf, boosting all frequencies below the selected frequency, and band 4 will become a high shelf, boosting all above the selected frequency. Note that the `Q' control will not have any effect when the shelf mode is on. `Q' control: In parametric mode, this will effect the width of the filter's response. Turned fully anti-clockwise the bandwidth is 0. 4, or 2. 5 octaves (a wide gently response). Fully clockwise, the `Q' is narrowed to 25, or 0. 04 octaves. E2 Operators Manual Page 7 Low Pass Filter Control: Adjust the cut-off frequency of the low pass filter from 250Hz to 22kHz(effectively off). Low Pass Filter Slope Key: Choose either a second order response (12dB per Octave roll-off) or a steeper 4th order response (24dB per Octave). Output Gain Control: To compensate for large amounts of cut or boost and bring the output level back to that at the input, use the output gain control, in conjunction with the meters. Output Meters: These meters permanently show the level after all processing, just before the digital to analogue converters. Page 8 E2 Operators Manual Rear Panel Connections Power Switch: turns the units mains supply off and on. Mains Fuse: located in a finger-proof holder adjacent to the mains inlet. A spare fuse is also located in this holder. Mains Inlet: connected via a standard IEC socket. Audio In-Out: 3 pin XLR sockets are provided for each channel. All are fully balanced, pin 2 hot, 3 cold, 1 screen. Always replace the fuse with the correct type and rating as shown on the rear panel legend. E2 Operators Manual Page 9 Operating the E2 Operation of the D2 is very straightforward, but there are a few points worth noting which, once understood, will make using the unit even easier. Switching the unit on and start-up procedure After plugging in the power and switching the power on suing the rear panel switch, confirmation is quickly given that all is well by all LEDs illuminating almost immediately after power-up. [. . . ] Centre/corner Freq: 20Hz to 20k in three ranges `Q': 0. 4 to 25 (2. 5 ­ 0. 04 Octaves) Gain: +15dB to ­25dB Input/Output Gain Both +15 dB range. Output meter: 7 point, -18dBu to +18dBu. Connectors Inputs: 3 pin female XLR Outputs: 3 pin male XLR. Power: 3 pin IEC Power: 60 to 250V ±15% @ 50/60Hz. [. . . ]
