NOTES ABOUT HUM:
While the SPA1000 has been designed to minimize the possibility of hum in the subwoofer system, it is still possible that a hum
will occur in rare circumstances. Its safety grounding can create a path for small amounts of 60 Hz energy to travel through the
line-level audio system. While not dangerous, this energy can cause diffi culty with the subwoofer auto signal sensing circuit,
and at the very least will interfere with the quiet enjoyment of your system. The fi rst course of action should be trying to make
sure that all of the audio components are connected to either the same electrical outlet, or at least into the same circuit branch.
Next, cable TV systems are notoriously the culprit, so be sure to try disconnecting all coaxial feeds that are connected to the
system. If this solves the problem, install a coaxial line isolator and reconnect the system. In the very worst case, a line-level
audio isolator/transformer connected to the line-in of the subwoofer amplifi er will usually solve the problem.
IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of electric shock, do not remove cover. No user serviceable parts inside. Refer servicing to qualifi ed personnel.
To reduce the risk of fi re and shock do not expose unit to rain or moisture. The unit should be connected to an earth grounded AC
electrical socket. The unit should be operated in a well ventilated area. Minimum clearance is 2 inches from the ventilation openings.
Note: Unit is set at the factory for 120V operation. Be sure to change the fuse (5A rating) before switching to 230V operation.

Summary

Notes About Hum

Specifications

Rated Power Output

Specifies the amplifier's output power into 8 and 4 ohm loads, with THD and duty cycle.

Signal to Noise Ratio

Measures the output signal level relative to the noise floor, expressed in A-weighted dB.

Efficiency

Indicates the percentage of input power converted into audio output power.

Input Impedance

The electrical resistance presented to the input signal source, measured in ohms.

Low Pass Adjustment

Defines the adjustable range for the low-pass filter crossover frequency.

Phase Adjustment

Allows selection between normal (0°) or reverse (180°) phase for subwoofer integration.

Parametric EQ

Details the adjustable parametric equalizer settings: frequency, bandwidth, and level.

Dimensions

Provides the physical width, height, and depth of the amplifier unit.

Enclosure Cutout

Specifies the recommended cutout dimensions for mounting in a subwoofer enclosure.

Power Requirements

Lists the required AC voltage and frequency for the amplifier's operation.

Stand-by Power Rating

Indicates the power consumed by the unit when in stand-by mode.

Weight

The total weight of the amplifier unit.

Important Safety Instructions

Electrical Shock Warning

Cautionary notice regarding risk of electrical shock and user-serviceable parts.

Input Connections

Left;Right Inputs

RCA jacks accepting standard line level inputs from a pre-amp source.

LFE Direct Input

RCA jack for mono LFE output, bypassing internal low-pass filter.

Power Input

IEC grounding type power input connector with integrated fuse holder.

Controls and Indicators

Low Pass and Gain Controls

Adjusts amplifier sensitivity to preamp output and controls system volume.

Low Pass Frequency

Sets the crossover frequency for the low-pass filter (30-200 Hz).

Power Switch

Manually turns the unit on/off and enables auto stand-by mode.

Power LED Indicator

Indicates amplifier status: stand-by (dim green), operational (bright green), clipping (red).

Phase Adjustment Switch

Compensates for acoustical/electrical speaker differences (0° or 180°).

Parametric EQ Frequency

Establishes the specific frequency (18-80 Hz) for EQ boost or cut.

Parametric EQ Bandwidth

Determines the width of the EQ curve (0.1-1.0) for targeted or broad effects.

Parametric EQ Level

Applies boost (up to 6dB) or cut (up to 14.5dB) at the selected frequency.

Output Lead for Subwoofer Driver

Connects amplifier to subwoofer driver with color-coded wires.
