Wharfedale SPX613, SPX815 Mono Mic/Line Input Channels, Hi-Z, USB Stereo Input and Output

SPX613 & SPX815 Powered Mixers

FEATURES AND CONTROLS

Mono Mic/Line Input Channels:

1. Low Impedance (Low Z) Mic Input jacks with switchable global phantom

power: The low noise, high headroom

microphones.

,,

,,

Low Z

mic inputs are for use with balanced, low impedance

2.	,,	,,
	,,Hi-Z	Line Level Input jacks: These 1/4 Tip, Ring, Sleeve (TRS) jacks are designed to be

connected to (-10 to +4dBu) balanced or unbalanced line level sources.

,,

3.,, Super Hi-Z inputs: Channels 6 & 7 on the SPX613 and Channels 8 & 9 on the SPX815 for connection of unbalanced, low level instrument signals such as an electric guitar or electric bass.

4.Stereo Line Level Input jacks: Channels 8 & 10 on the SPX613 and Channels 10 & 12 on

,,

the SPX815. These dual 1/4 Tip, Ring, Sleeve (TRS) and dual RCA phono jacks are designed to be connected to (-10 to +4dBu) balanced or unbalanced line level sources. A mono signal can be connected by using only the left input jack. The mono signal, connected like this, will be routed to both left and right outputs and will be controlled by the position of the pan knob of that channel.

5. USB Stereo Input and Output

This digital input and output is provided to allow for the direct digital connection to a computer USB port for both the playback and recording of signals to and from a digital audio software program. The output signal is derived from the stereo Main Mix, pre master level, and the input signal is routed to

channel input 9-10 on the SPX613 and channel 12-13 on the SPX815. Consult the manufacturer of

,,

your software for details. The USB input is not disabled by the input of line level signals to the 1/4 jacks on the channel. Both the analog and digital signal can be used simultaneously.

6.Level Control: Adjusts the level of the input signal to the mixer.

7.TRIM Control: In order to achieve the best signal to noise ratio and adequate dynamic range, the input preamp level of each mono channel is controlled by the TRIM control knob on each channel. To set the TRIM control, watch the PEAK LED while the signal source for that channel is active (whether it be a singer using a microphone or an instrument connected to the LINE INPUT of the channel). If the PEAK LED (#8) on the channel lights up consistently, the Gain Control is set too high. The ideal setting is obtained, when the PEAK LED only flashes periodically.

8.PEAK indicator LED: The PEAK indicator LED will illuminate when the input signal level is 3dB before clipping (signal distortion).

9.PAN Control: On the mono channels, the PAN control adjusts the balance of the signal being sent to the left and right MAIN MIX. Turning the PAN control fully left on a stereo channel will cause the right input's signal level to decrease. Turning the PAN control fully right on a stereo channel will cause the left input's signal level to decrease.

10.EQ (Equalization): Each mono channel on the SPX Series mixers features a three band

	,,	,,
Equalization (		EQ ) section. Each band allows for up to 15 decibels of boost (increase) or cut

(decrease) of the signal in the tone range for which it controls (HI, MID, LOW). In the center detented position, the equalizer is bypassed (FLAT) and the control has no effect on the tonal characteristics of the signal. The HI EQ control is centered at 12kHz, the MID EQ control is centered at 2.5kHz and the LOW EQ control is centered at 80Hz. Stereo channels have two band equalization with the HI EQ control is centered at 10kHz and the LOW EQ control is centered at 100Hz.
