- Page 8 The KW122, KW152, and KW153 are equipped with a 35 mm pole socket that allows use on a speaker stand or on a pole over a KW181 subwoofer. The pole socket on the KW122 and KW152 features the QSC Tilt-Direct™ system for tilting the enclosures down 7.5° while on a pole. The pole socket on the KW153 does not allow tilting.
- Page 9 Installation Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabinets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated component could significantly reduce the strength of the installation or placement. Any such condition severely reduces the safety of the installation and should be immediately corrected. Use only hardware which is rated for the loading conditions of the installation and any possible short-term, unexpected overloading.
- Page 10 As shipped from the factory, each installation point has a flat head screw installed to acoustically seal the loudspeaker system and retain the sleek look of the enclosure. These installation points are designed for use with the QSC forged shoulder eyebolts included in the available accessory kit, model number KW M10 KIT.

Page 11: Input Connections
AC mains power cord is properly attached to the loudspeaker and plugged into the AC source outlet. Verify the outlet is functioning properly. If the AC mains cord is serviceable and the AC mains outlet is operating properly, but the loudspeaker fails to operate, the loudspeaker may require servicing. Contact QSC’s Technical Services department. System Power Sequencing Proper power-on/power-off sequencing can help prevent unexpected sounds from being produced by the system (pops, clicks, thumps). -
Page 12: Balanced Inputs
Channel A Channel A accepts either microphone or line level inputs. The MIC/LINE IN A inputs can use either a: • Male XLR connector, or a • Male 1/4" phone jack (TS or TRS type). The KW122, KW152, and KW153 feature a 4-position rotary switch (MIC/LINE GAIN) to provide input gain flexibility. •... - Page 13 Unbalanced Inputs Connect to the plug as shown. If a 3 conductor (TRS) plug is used to connect an unbalanced source, Pin 3 and pin 1 must be connected with a jumper as shown. Ground 1 = Shield (ground) — 2 = Plus (+) Inverting Input 3 = Minus (-)

Output Connections KW122, KW152, KW153 1. Channel A Line Level Discrete Output 2. Channel B Line Level Discrete Output 3. LINE OUT (POST GAIN – MIX) 4. Channel A GAIN Knob 5. Channel B GAIN Knob Both Channel A and Channel B have discrete, direct outputs on female XLR connectors. The signal on this output is exactly equivalent to the signal from the corresponding input. - Page 15 KW181 Both Channel A and Channel B have discrete, direct outputs on female XLR connectors. The signal on this output is exactly equivalent to the signal from the corresponding input. The level of the output signal is not affected by the gain set on the subwoofer gain knob. If a unit is OFF, any signal present on MIC/LINE IN A or LINE IN B passes through to the respective discrete outputs.
- Page 16 These functions include crossovers, time alignment, limiting and protection, thermal management and a number of proprietary features. QSC has designed exclusive DSP functions that greatly enhance the capabilities and performance of the KW Series systems.
- Page 17 High-frequency EQ On the KW122, KW152 and KW153 there are two high-frequency settings. From the factory, the switch is set to FLAT. This means that the loudspeaker system is producing a flat response through the vocal band. This is the standard setting for most applications. In voice-only reproduction, the switch can be set to the VOCAL BOOST setting.

Page 18: Additional Features
Additional Features Standby All KW Series models are equipped with an automatic standby feature to conserve energy when the systems are not in use. If no signal is present on any input, or the gain knob is turned to off for five minutes, the power amplifier goes into standby and the green STBY LED illuminates. In this mode, the amplifier is powered down. - Page 19 Remote Gain Attenuator A 3-pin “Euro” connector is provided to attenuate the volume of the KW Series loudspeaker or put the system into standby from a remote location. The Remote Gain connector can only attenuate the output signal level below the level set by the Channel A and Channel B Gain knobs.
