Optional Equalizer

Card Information

The Model 1800-VI is available with

optional Bose

circuit cards providing

active equalization for all Bose Profes-

sional Products loudspeaker systems.

Each channel has its own discrete circuit

card input slot. Therefore, a single ampli-

fier can drive one channel of 402

loudspeakers and another channel of

502

loudspeakers, for example.

Active equalization plug-in circuit cards

provide proper equalization for all Bose

Professional Products loudspeakers

without use of a separate controller. A

Line Level EQ out is also provided to

connect additional 1800-VI amplifiers

without the need for extra EQ circuit cards.

For 70V or 100V Operation

When using a single channel of the 1800-VI amplifier to drive a 70-volt or 100-volt line:

with these agency regulations: UL6500

(ETL marking), CSA C22.2 No.1,

EN60065:1985, and EU emission and

immunity regulations for

Engineers' and Architects' Specifications

The Model 1800-VI amplifier shall deliver

450 watts of continuous power, both

channels driven, into 8

0.2% distortion from 20Hz to 20kHz. The

amplifier shall deliver 600 watts of

continuous power, both channels driven,

into 4

with less than 0.2% distortion

from 20Hz to 20kHz. In bridged-mono

operation, the amplifier shall deliver 1400

watts of continuous power into 8

less than 0.2% distortion.

There shall be two parallel input connec-

tors for each of the two input channels.

One of the input connectors shall be

capable of connecting to both a

and an XLR connector (only one input

connector can be accepted at one time).

The second input connector shall consist

of a quick connect terminal block

connector. The two output multi-way

binding posts shall be capable of accept-

ing either spade-lug, bare wire, or banana

connections. There shall be two

line level equalized signal outputs, cor-

responding to the two channels. This

signal shall be accessed after the internal

equalization card (if installed) and prior to

the internal amplification section.

The channel separation for the two

channels shall be greater than 65dB @

1kHz and greater than 55dB @ 10kHz.

The dynamic headroom shall be greater

than 1.0dB. The power bandwidth, from

5Hz to 40kHz, shall be +0dB, -3dB.

The frequency response, from 20Hz to

20kHz, shall be 0.75dB. The damping

factor shall be at least 170.

The input impedance shall be 25k ,

unbalanced, each leg to ground and

50k

balanced. The high sensitivity shall

be 0.775 volts rms for rated power into

@ 1kHz, and 32mV rms for 1 watt

into 4

@ 1kHz. The low sensitivity shall

be 1.5 volts rms for rated power into 4

@ 1kHz and 61mV rms for 1 watt into 4

@ 1kHz.

The gain shall be 36.0dB, 0.5dB with

the high input sensitivity configuration.

The gain shall be 30.3dB, 0.5dB with

the low input sensitivity configuration.

The amplifier shall consume 1500 watts

of continuous power into 8

watts into 4 . The unit shall be 3.5" (H)

x 19" (W) x 13.25" (D) (89 mm x 483 mm

x 337 mm). The net weight shall be

33 lb (15 kg).
