Dsx Front Panel; Channel-1; Channel-2; Master Section - Ultrasound DSX POWERSTACK Operating Manual

INPUT-1: This combo input is designed for both MIC level (XLR) (XLR input provides Phantom power**) or Instrument level
(¼") signals. (The ¼" TRS
keyboards and drum machines. It accepts both balanced and unbalanced inputs) (Channel-1 is designed as a generic "flat
response" channel which is suitable for any acoustic instrument level or microphone signal)
BASS: Adjusts the amount of cut or boost in the low frequency range.
TREBLE: Adjusts the amount of cut or boost in the high frequency range.
VOLUME: Controls the overall volume level of CHANNEL-1.
Note 1: When CHANNEL-1 is not in use, be sure to turn all controls to the minimum level to avoid any unwanted noise
being passed through the amplifier.
INPUT-2: Combo Input designed for both MIC level (XLR) and Instrument level (¼") signals. (Channel-2 is designed primarily for
acoustic guitar) Try both channels to find out which channel works best for your application, some players like Channel-1 and
others prefer Channel-2. With the myriad of guitars, pick-up systems, and playing styles out there, one of the channels will sound
great with your gear. (XLR input provides Phantom power**)
VOLUME: Controls the overall volume of CHANNEL-2.
BASS: Adjusts the amount of cut or boost in the low frequency range.
TREBLE: Adjusts the amount of cut or boost in the high frequency range.
Notch Filter HZ: Sets the frequency of the 18db cut NOTCH FILTER that is used to control resonant feedback.
Notch Filter: ON/OFF - Enables or disables the notch filter control.
Shape: ON/OFF This toggle switch enables or disables the SHAPE control. The shape control is a mid dip control. In the on
position the mid frequencies will be cut and the high and low frequencies will be boosted.

PHANTOM POWER –
An internal phantom power source (13.6 volts) is provided for use with condenser mics. This power source is on at all times and does not affect the standard
operation of the amp, even when a condenser mic is not used. We use the DIN 45-596-P12 volt standard which will operate virtually all of the live sound reinforcement condenser
microphones on the market. Some "boutique" externally biased condenser mics will not be compatible and will require 48 volt phantom power. We suggest live sound condenser mics by:
AKG (C4500B,4000B, etc.), Audio Technica (AT3035, 3032, Pro Series, etc.), CAD, Shure and Crown.
Effects Assign: This 3 way toggle switch allows the digital effects to be routed to CH-1, CH-2, or if in the middle position will
supply effect for both channels.
Effects LEVEL: Controls the amount of digital effect mixed in to the guitar signal from 0% to 50%.
Effects MODE: This is a rotary encoder, which selects 1 of 16 different digital effects. See Digital Effects Program List.
MASTER VOLUME: Adjusts the overall loudness of the amplifier.
Pilot Light/Limit Indicator : When GREEN, this LED indicates that the power is turned on. If the power amplifier reaches full
power output, the on board Limiter will be enabled and this LED will turn RED.
