integrated equalizer, amplifier, and distribution auto-former electronically balanced differential line level input stage 9-band graphic equalizer (±15dB on ISO center frequencies) 60W of power into 4Ω, 8Ω, or distributed speaker systems HPF (18dB/octave @ 180Hz) selectable with internal jumper passively cooled amplifier eliminates fan noise/maintenance complete short-circuit and thermal protection with auto-reset turn-on muting to provide noiseless power- switching front panel indicators for power, signal present, and peak input/output connections provided on barrier strip terminals table-top design with rack-mounting kit included covered by Biamp Systems’ five-year warranty

IMPORTANT SAFETY INSTRUCTIONS

Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with a dry cloth.
Do not block any of the ventilation openings.
Install in accordance with the manufacturer’s instructions.

WARNING – To reduce the risk of electric shock, do not expose this apparatus to rain or moisture.

The apparatus shall not be exposed to dripping or splashing and no objects, such as vases, shall be placed on the apparatus.
Unplug this apparatus during lightning storms or when unused for long periods of time.
Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. When the provided plug does not fit into your outlet, consult an electrician for the replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
Use only attachments/accessories specified by the manufacturer.
Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer or sold with the apparatus.
When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
Unplug this apparatus during lightning storms or when unused for long periods of time.
The appliance inlet shall be readily operable once installed.
WARNING – Terminals marked with the following symbol are Hazardous. Connections to these terminals must be made by qualified personnel.

SAFETY INFORMATION
The words WARNING and CAUTION throughout the manual, and on the device, call attention to important safety information. These words have the following meanings.
WARNING: The related information alerts you to conditions that could result in serious injury or damage to property if the instructions are not followed properly.
CAUTION
The related information instructs you on how to prevent damage to the equipment or how to avoid conditions that could result in minor injury if proper steps are not followed.

Product labeling and the operation manual may use the internationally recognized symbols defined below to note safety messages.
The lightning flash with the arrowhead symbol, enclosed within a triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the apparatus’s enclosure or at connection terminals that may be of sufficient magnitude to constitute a risk of electrical shock.
The exclamation point, enclosed within a triangle, is intended to alert the user to important installation, operation, and maintenance (servicing) instructions in the literature accompanying the apparatus.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.
CAUTION
Installation of this apparatus should be made by a qualified installation person and should conform to all applicable local codes.

Modification and optional equipment information referenced in this manual is for use by qualified installation and service personnel only.

CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK,
DO NOT REMOVE COVER.
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

FRONT PANEL

Graphic Equalizer. The graphic equalizer section divides the audio spectrum into 9 bands. Each band is one octave wide and is centered on ISO standard frequencies. Each control provides up to 15 dB of boost or cut at its center frequency. Each mark above and below the center position indicates a change of 3 dB. NOTE: When using the D60EQ auto former (for 8Ω, 70V, or 100V output) lower frequency filters (64Hz, 125Hz, & 250Hz) should not be boosted .
Level Control. The level control determines the amplitude of the output signal.
On Indicator. This green LED indicates that the AC power is on.
Signal Present Indicator. This green LED turns on when the output signal is greater than or equal to approximately -20 dBu (80 mv) at the 4 ohm output.
Peak Indicator. This red LED turns on when the output signal is either beginning to clip or is on the verge of clipping. The level control should be adjusted so the Peak Indicator does not light during normal operation.
Power Switch. Turns on or off the AC power to the unit.

AC Power Cord. Connect to ~115/230 VAC 50/60 Hz AC power. Make sure that the line voltage selector switch and fuse have been correctly set before plugging in. Do not remove or defeat the AC ground prong on the plug, as this constitutes a shock hazard.
Line Voltage Selector Switch. Set this switch to “115” for nominal line voltages of 110-120 VAC. Set this switch to “230” for nominal line voltages of 220-240 VAC. Make sure that the appropriate fuse is installed when changing voltage selections. The unit is set for 115-volt operation when shipped from the factory.
Fuse. This is the AC power fuse. Replace fuse only with the same type and value. For 115-volt operation, use a T 2A L 250V fuse. For 230-volt operation, use a T 1A L 250V fuse.
Output Barrier Strip. The output barrier strip provides connections for the output of the amplifier. The Common terminal is the output “ground” connection. When the unit is shipped from the factory, the distribution auto former is not hooked up and the signal is only present at the 4 ohm output. To use the 8Ω, 70V, or 100V outputs, the jumper wire must be connected from the 4Ω output terminal to the autoformer input terminal. NOTE: From the factory, the D60EQ has an 18dB/octave 180Hz high-pass filter enabled. This high-pass filter must remain enabled whenever an autoformer output is being used (8Ω, 70V, or 100V). The high-pass filter should be disabled only when using the ‘direct’ 4Ω output (see Options & Accessories on page 8). CAUTION: High voltages may be present at the output terminals. Be sure that the AC power is off when making connections.
Input Barrier Strip. The input barrier strip provides connections for the balanced input to the amplifier. The bottom three terminals on this barrier strip are unused.

OPTIONS & ACCESSORIES

CAUTION: Modifications must be performed by qualified service professionals. AC power must be disconnected, and the top panel must be removed before performing any of the following modifications to the D60EQ.

High-Pass Filter
A jumper strap labeled ‘FILTER’ on the amplifier circuit board enables or disables an 18dB/octave 180Hz high-pass filter. When the strap is in the “IN” (up) position, the filter is enabled. When the strap is in the “OUT” (down) position, the filter is disabled. To avoid high magnetization currents which cause the amplifier to current limit and distort the output signal when low frequencies are present, the high pass filter must be strapped “IN” when using the auto former (8 ohm, 70V, 100V) outputs. This strap is set “IN” when the unit is shipped from the factory.
Rack Mounting
Rack mounting brackets are provided with the D60EQ. To install these brackets, the top cover of the unit must first be removed. The brackets are then attached to the top cover using the hardware supplied. The top cover is then reattached.
