D60EQ

INTRODUCTION

The D60EQ is an integrated power amplifier, distribution autoformer, and
9-band graphic equalizer, ideally suited for paging/background music
systems, as well as for zone systems in church, theater, restaurant and
hotel applications. The D60EQ is easy to install, and is covered by a
five-year warranty.

D60EQ features include:

♦ integrated equalizer, amplifier, and distribution autoformer

♦ electronically balanced differential line level input stage

♦ 9-band graphic equalizer (±15dB on ISO center frequencies)

♦ 60W of power into 4

Ω, 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 manufacturers
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 with 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 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 teminals must be
made by qualified personnel.

FRONT PANEL

1. 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 autoformer (for 8
100V output) lower frequency filters
(64Hz, 125Hz, & 250Hz) should not be
boosted (see Output Barrier Strip on
next page).

2. Level Control. The level control
determines the amplitude of the output
signal.

3. On Indicator. This green LED indicates
that AC power is on.

Ω, 70V, or

4. 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.

5. 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.

6. Power Switch. Turns on or off the AC
power to the unit.

1. 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.

2. 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.

3. Fuse. This is the AC power fuse.
Replace fuse only with 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.

4. 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
autoformer is not hooked up and signal
is only present at the 4 ohm output. To
use the 8

Ω, 70V, or 100V outputs, the

jumper wire must be connected from the

Ω output terminal to the autoformer

4
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 (8
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.

5. 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.

FILTER

IN

OUT

High-Pass Filter

Rack Mounting

jumper strap labelled ‘FILTER’ on the amplifie
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 autoformer (8 ohm, 70V, 100V)
outputs. This strap is set "IN" when the unit is
shipped from the factory.

Rack mounting brackets are provided with the
D60EQ. To install these brackets, the top cove
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.
