IMPORTANT SAFETY INSTRUCTIONS
FRONT PANEL
1. When first powering-up the amp, keep the amplifier gain controls all the way off, in order to prevent from being
potentially damaged and from producing annoyed sounds caused by defective cables or hookups. When turning
up gain control, do it gradually, until normal operation is verified. These precautions are necessary with all high power amplifiers, since they have enough power to blow most speakers in abnormal situations.
2. Check the AC Voltage before connectiong the AC plug.
PRECAUTIONS
1. GAIN CONTROLS KNOB
CSR154 has a level control knob for four channel respectively. Turning clockwise will increase its gain, and
counter-clockwise will reduce its gain. Please always power-up with the volume all the way down, and increase
volume slowly to make sure that no conditions what so ever could annoy your audience or harm your speakers.
2. SIGNAL INDICATOR
Each channel of the CSR154 features a signal LED for showing an audio signal at the input to the channel.
3. MASTER / SLAVE SWITCH
Always take slave mode, input signal as input 1 and 2, there are four output.
4. Power switch and indicator
Turn on this unit with this power On / Off switch, and the power indicator will illuminate immediately. Always
start with gain control all the way down before powering-up to avoid abnormal sound from defective cables
or hookups.
BACK PANEL
5. CH 1 / CH2 / CH3 / CH4 INPUT
Connect your source to either the XLR or 1 / 4" phone jack, which are commonly used for both mobile and istallation
set-ups.
6. OUTPUT
This product has Speakon Speaker outputs, so you can use speaker cables with Speakon connectors. These locking
connectors are easy to attach and are capable of handling high currents and low impedance loads.
7. POWER
This is where you connect the AC linecord to provide AC power. Plug the linecord into an AC socket properly configured
for your particular model.
