ASHLY MX-508 มิกเซอร์ Stereo Mixer 8-Channel Mic/Line 3RU, 5 Year Warranty

Features:

High-gain microphone preamps with very low noise and distortion

Three-band input equalizers with tunable mid-range

48 Volt phantom power for use with any condenser microphones

5 Year Warranty

The MX-508 is an eight-input stereo rackmountable mixer. Designed for a multitude of applications, the MX-508 has an extensive mix of features for a small unit combined with excellent sound and quiet performance.

The MX-508 features 84 dB of gain to ensure full output with low-level or distant microphones. Several years of research went into the microphone preamp and the result is a discrete circuit with better than -129 dBu Equivalent Input Noise (EIN) and very low distortion. Low and High Shelving EQ combined with mid-band peaking EQ tunable from 140Hz and 8 kHz make for a very flexible tone control. Phantom power of +48 VDC is provided for condenser microphones via a switch on the front panel. Precision input transformers are easily field-installable, and each input has its own 20dB pad switch. Variable gain trim and Mic/Line selection switches are also found on each input channel. Rounding out the list of standard input features are a Peak Clip indicator, two Aux Sends (factory-set with one pre-EQ and level and the other post-EQ and level, these sends may be modified by a qualified technician), In/Out channel patching, Level and Pan controls, and both balanced XLR Microphone and TRS Line inputs.

Transformer-balanced Left and Right XLR outputs are standard, as are balanced Left and Right TRS 1/4" outs. There is also an independent Mono output with its own front panel level control, as well as a selectable Headphone output with Level Control. There are Pre-Master Sub In/Out patch points for linking other mixers, such as the Ashly MX-206 six-input microphone mixer. Peak Clip indicators are also provided for the Outputs, and the 10-Segment LED Meters may be selected to monitor either Program Left and Right or Aux 1 and 2. Maximum output level is +24dB into 600 ohms.

The MX-508 also has two Master Aux Sends and two panable Master Aux Returns (one stereo and the other mono). There is an additional stereo RCA Tape/CD Input< with level control to the Mains or Aux 1. Stereo RCA Tape Outputs are also provided. The MX-508 combines traditional Ashly quality with internally modular construction in a package offering outstanding value and reliability. As with all Ashly products, the MX-508 is backed by the Company's exclusive Five Year Worry-Free Warranty.
