The LM-8ST is a line mixer that mixes eight stereo line inputs. In addition to the TRS balance line inputs available for each channel, an XLR balanced mic input is possible with channel-1. The LM-8ST supports a simple PA system that requires a microphone.Since there two independent output busses, the users can output using different mixes. Each output buss is equipped with an XLR balanced output and RCA unbalanced output. Furthermore, the ST 2/AUX buss can be used as an AUX buss; as such, this allows the user to use the ST 2/AUX buss for sending effects (input from either buss can be used for effect return). This device can be used for various applications, including stereo source selection at stores, restaurants, banquet facilities, and acoustic facilities, as well as using a microphone to make announcements and sound mixing, and even as an on-stage keyboard mixer and sub-mixer.Main Features:8 stereo channel / 4-buss line mixer8 stereo 1/4″ TRS balanced inputs with 10/+4dB switch1U rack mountableMic input with trim control on front panel2-segment LED meter per channelST1 and ST2/AUX level control per channelST1 and ST2/AUX master level controlsEach channel switchable to ST2 (pre fader) or AUX (post) output1/4″ and 1/8″ stereo headphone outputsXLR balanced ouptuts for ST1 and ST2/AUXStereo balanced buss output/input for cascadeGround lift switch and terminalSpecifications:Audio Inputs/Outputs:MIC IN:-Connector: XLR-3-31 (1: GND, 2: HOT: 3: COLD) 1-Input impedance: 2.4k-Nominal input level: 58dBu (1mV) to 12dBu (195mV)-Maximum input level: +10dBu (2.45V)STEREO IN:-Connector: 1/4″ (6.3mm) TRS Phone jack (Top: HOT, Ring: COLD, Sleeve: GND) 8 pairs-Input impedance: 16k-Nominal input level: +4dBu (1.23V)-Maximum input level: +24dBu (12.3V)MASTER BUSS IN:-Connector: 1/4″ (6.3mm) TRS Phone jack (Top: HOT, Ring: COLD, Sleeve: GND) 1 pair-Input impedance: 16k-Nominal input level: +4dBu (1.23V)-Maximum input level: +24dBu (12.3V)ST1, ST2/AUX OUT:-Connector: XLR-3-32 Phone jack (1: GND, 2: HOT, 3: COLD) 2 pairs-Input impedance: 94-Nominal input level: +4dBu (1.23V)-Maximum input level: +24dBu (12.3V)ST1, ST2/AUX OUT:-Connector: RCA Pin jack 2 pairs-Input impedance: 200-Nominal input level: 10dBu (0.3V)-Maximum input level: +10dBu (3.16V)BUSS OUT:-Connector: 1/4″ (6.3mm) TRS Phone jack (Top: HOT, Ring: COLD, Sleeve: GND) 1 pair-Input impedance: 94-Nominal input level: +4dBu (1.23V)-Maximum input level: +24dBu (12.3V)PHONES OUT:-Connector: 1/4″ (6.3mm) Stereo Phone jack 1-Maximum output level: 250mW + 250mW (32)Power: AC 100 – 240V, 50/60HzPower consumption: 15WDimensions (WHD): 19.0″ 1.73″ 11.0″ / 482 44 280 mmWeight: 8.4 lbs. / 3.8 kgIncluded items: Power cord, Rackmounting screw kit, Owner’s manual (with warranty)
