zZounds Gear Experts Say...
7-band EQ. (2) 200-watt amps bridgable to 400 mono.
Overview
For the maximum in usable channels and multiple stereo input devices, the PX900DLX offers XLR low impedance and 1/4 in. high impedance inputs on the first 4 channels, and the last 5 channels all have XLR and stereo line-in 1/4 in. jacks. The power platform and master section features are the same as the PX700DLX.
These are extremely easy to use, and are excellent for small combos or institutional use where quality of sound and ease of use are the primary concerns, but a slightly more professional feature set is desired. They all feature Crate's 5-year transferable warranty and are built to last.
Graphic EQs
These 7-band graphic equalizers allow customization and shaping of the output signals to match room acoustics and enhance the sound. Use the selector switch to determine where the equalization will be applied: either to the main and monitor output signals, or to the main 1 and main 2 output signals.
LED Meters/Limiter Indicators
These LED meters monitor the output signal levels for either the main and monitor output signals, or the main 1 and main 2 output signals (dependent on the setting of the selector switch). The red LEDs illuminate when the internal limiter is engaged to prevent the signal from being clipped (clipping results in overdrive distortion and should be avoided). If the limiter LEDs flash continuously or remain on constantly during use, reduce the output signal levels until they flash only on strong signal peaks.
Effects Returns
Use these controls to… read more adjust the magnitude of the effects applied to the output signals. Use the selector switch to determine where the effects will be applied: either to the main and monitor output signals, or to the main 1 and main 2 output signals.
Main/Monitor/Main1/Main 2
Use this switch to select whether the graphic EQs, LED meters, and master level controls are assigned to the Main and Monitor outputs (switch in the out position) or to the Main 1 and Main 2 outputs (switch depressed. When this switch is in the out position, the Main/Main 1 graphic EQ controls the signal to power amp #1, the output of which is connected to the Main Output jack. Also, the Monitor/Main 2 graphic EQ controls the signal to power amp, the output of which is connected to the Monitor Output jack. When this switch is depressed, the Main/Main 1 graphic EQ controls the signal to power amp #1, the output of which is connected to the Main 1 Speaker Output jacks. Also, the Monitor/Main 2 graphic EQ controls the signal to power amp #2, the output of which is connected to the Main 2 Speaker Output jacks.
Effects Send
Use this control to set the overall signal level sent to the internal DSP or external effects (if used).
Aux In
Use this control to set the input signal level of the aux in jack.
Tape In
Use this control to set the input signal level of the tape in jacks.
Power LED
This LED illuminates when the mixer is on.
Phantom +48V
This switch, when depressed, applies +48 volts DC to pins 2 and 3 of each channel's XLR input jacks. This allows use of microphones that require a source of phantom power for proper operation (mics not requiring phantom power will not be affected by the presence of the DC voltage). The adjacent LED illuminates when the phantom power is on.
DSP Selectors
Use these switches to select the type of digital signal processing effect to be applied — vocal, large hall, and small hall are reverberation effects; delay is a digital delay effect.
DSP On
Use this switch to activate the internal digital signal processor. When this switch is depressed, the selected DSP effect is activated.
Effects Send
Use this jack to send a signal to an external effects device. The signal level at this jack is set by the effects send control.
Footswitch
Use this jack to connect a footswitch for remote on/off control of the DSP and external effects device. The footswitch must be a normally open, momentary type such as the Crate model #FSIU. The wiring for the footswitch is as shown:
Aux In
Use this jack as the return jack when using an external effects device, or to feed another mixer's signal into the PX700DLX/PX900DLX. This jack is post-input channel, pre-EQ, and pre-power amp.
Tape In
Use these jacks to connect the outputs of a tape deck or CD player to the mixer. The playback signal level is set by the tape in level control.
Tape Out
Use these jacks to connect the mixer to a tape recorder. These jacks are is post-EQ, pre-master, and their signal level is determined by the channel level controls.
Monitor Out
Use this jack to send a line level, monitor mix signal to the power amplifier you are using for your monitor speakers.
Main Out
Use this jack to send a line level, main mix signal to an external power amplifier (if used), a recording console, or to the aux in jack of another PX700DLX/PX900DLX.
Power Amp Switch
Use this switch to set the amplifier for mono bridged operation (switch to the left) or for main/monitor operation (switch to the right).
Main 1/Main 2 Speakers
Use these jacks to connect the mixer to your PA speakers, only when the power amp switch is set to the main/monitor position. Observe the 4-ohm minimum load rating and all other speaker information printed on the rear of the mixer.
Bridge Speaker
Use this jack to connect the mixer to your PA speakers, only when the power amp switch is set to the bridge position. Observe the 8-ohm minimum load rating and all other speaker information printed on the rear of the mixer.
AC Line Cord
Connect this cord to a suitable source of AC power, as indicated to the right of the cable. Do not attempt to bypass the ground connection of this power cable!

"Hidden gem"
Verified Customer
zZounds has verified that this reviewer made a purchase from us.
As a mobile DJ, I will use this as my back-up amp and to sometimes power my subwoofer. Occasionally, I will use it for PA applications.
Sound
Rich & powerful sound.
Features
This is a very versatile box mixer and can be used for band/DJ applications. I like how you can bridge it MONO so you can run a subwoofer. I would like to see a EQ on/off indicator switch for each channel. The carry handle is on the side and I think Crate should have mounted it on the top to make it easier to carry. All I did was unscrew it from the side and mount it on the top.
Quality
Solid construction. It seems durable. Crate has a great rep for building quality sound equipment.
Value
I paid $400. There are some box mixers that cost more and some that cost less. This particular model is 5 years old and discontinued.
Manufacturer Support
How about a dust cover?
The Wow Factor
Before purchasing the Crate, I bought 2 Alto box mixers, both of which were defective upon first using. There was not much else in stock. I admit that Crate was not my first choice, but I am glad I purchased it.
