SAFETY INFORMATION
1.Parts that have special safety characteristics are identified by the 
symbol on schematics or by special notes on the parts list. Use only replacement parts that have critical characteristics recommended by the manufacturer.
2.Make leakage current or resistance measurements to determine that exposed parts are acceptably insulated from the supply circuit before returning the unit to the customer. Refer to Paragraph 84 of UL 1270. Use the following checks to perform these measurements:
A.Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI) C101.1 “Leakage Current for Appliances” and Underwriters Laboratories (UL) 1492 (71). With the unit AC switch first in the ON position, then in the OFF position, measure from a known earth ground (metal water pipe, conduit, etc.) to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.
B.Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic cabinet part on the unit. When the exposed metallic part has a return path to the chassis, the
reading should be between 1 and 5.2 Megohms. When there is no return path to the chassis, the reading must be “infinite”. If it is not within the limits specified, there is the possibility of a shock hazard, and the unit must be repaired and rechecked before it is returned to the customer.

THEORY OF OPERATION
These Equalizer cards are designed to be installed into the AmPlus™ 50 and 100 amplifiers and the Bose® 1600 Series VI and 1800 Series V/VI amplifiers. The EQ cards included in this service manual are as follows; 402® series I and II, 502®A, 502B, 502BEX, 802® series II and III, Model 1B, Model 8, Model 25/32, Panaray® LT series II 3202®, 4402®, 9702®, and FreeSpace® 360 Surface and In Ground.
The FreeSpace 360 loudspeaker requires equalization, and this equalization is a function of the installation. There are two variants of the card that implement EQ curves for these
installation situations:
•In Ground (when the FreeSpace 360 loudspeaker is mounted in the ground).
The appropriate EQ curve for soft or hard ground is selected with a slide switch on the card. When S1 is in the SOFT position, the Soft Ground EQ is used; when S1 is in the HARD position, the Hard Ground EQ is used.
•In the Surface variant, S1 is omitted and jumpered to the SURFACE position.
Note: Refer to the FreeSpace 360 Surface or In-Ground schematic diagrams, as appropriate, for the following explanation. The designators inside the brackets "[ ]" are the schematic grid coordinates which are provided in order to make it easier to locate components on the schematic sheet indicated in the description. Components shown on the schematic as
OPT (optional) are not used in that particular configuration. Also refer to the EQ curves on page 7 of this manual for an overview of the frequency response of each of the 360 applications.
The input signal is applied to these cards at JP1 pin 4. The first section at the input, U2-B [D7], combines a first order high-pass filter with one section of a parametric cut filter. The parametric is set for -15dB at 27 Hz and provides a steep slope below about 80 Hz The equalization is segmented, with one block (U2 and U1), all sections [D1-8] dedicated to bass region equalization. Following the output of this section, U2-A [D1], the signal is presented to two parallel equalization paths, one comprised of U3 [B4-7], U4-B [C3], and dedicated to EQ for mounting in soft ground of the FreeSpace 360 loudspeaker. The other path, comprised of U5 [B4-7],
U4-A [B3] provides equalization for the FreeSpace 360 loudspeaker in hard ground installations. In the case of the FreeSpace Surface EQ card, the bottom leg of the equalizer card is not
used.
The operation of all three equalizers is similar. Considering the bass equalizer, we see U2-B's [D7] output passed through R8 [D7] and into the non-inverting input of U2-A [D2]. This input is extended as a bus to which EQ sections Bass 1 [D6] and Bass 2 [D5] are connected. These will introduce dips into the audio response to provide bass cut as required. Sections Bass 3 [D4] and Bass 4 [D3] are connected to a bus extended from the inverting input of U2-A [D2] and provide bass boost. See Figures 1,2 and 3 for the EQ curves for the various equalizer cards.
Each of the EQ sections utilizes a gyrator-connected op-amp in conjunction with a series capacitance to simulate an LCR series tuned circuit. The values of the capacitors and resistors are chosen to implement EQ dips and/or peaks at the appropriate frequency, amplitude and Q to realize the desired EQ curves. On the In-Ground EQ card, S1 [B2] selects either the HARD or the SOFT mount EQ curve.
The output signal is taken from JP1 pin 5, and returns to the amplifier. The equalizer cards are sensed by the amplifiers as follows. In the AmPlus 50 and 100 amplifiers, Pin 12 of J1 [B2] is grounded and is sensed by the dynamic EQ circuit on sheet 2 of the AmPlus 50 and 100 schematic diagrams. In the 1600/1800 amplifiers, the input module detects the presence of EQ cards via J7-6 and J6-6. Without the card installed these pins are pulled high (+15V). This logic high signal is also applied to the control pins of the switch ICs which selects the A (unequalized) input. When an EQ is plugged into J7 and/or J6 pin 6, the EQ is detected and pulls the control pin low (+7.5V), turning on the corresponding LED(s) and switching the IC to the B input which will then select the output of the EQ card to be passed on to the amplifier.

THEORY OF OPERATION
The Model 1B EQ card is intended for use in the AmPlus™ 50 and 100 amplifiers as well as the 1800 V, 1600 and 1800 VI professional amplifiers. It accepts a full range (50 Hz to 16 kHz) signal, equalizes it, and passes a full range signal back to the main amplifier signal path.
Refer to the FreeSpace® Model 1B EQ card schematic diagram, sheet 1 of 1 for the following information.
Note: The designators inside the brackets “[ ]” are the schematic grid coordinates which are provided in order to make it easier to locate components on the schematic sheet indicated in the description.
The equalization is segmented, with one block (U2 and U1, all sections [D1-8]) dedicated to bass region equalization for the Model 1B Bass module. Following the output of this section, U2A [D1], the signal is presented to two parallel equalization paths, one comprised of U3 [B4- 7], U4A [4-7], U4B [C3], and dedicated to EQ for surface mounted Bose® FreeSpace System satellite speakers (Model 25 and 32). The other path, comprised of U5 [B4-7], U4A [B3] provides equalization for Bose Model 8 flush-mount satellite speakers.
The operation of all three equalizers is similar. Considering the bass equalizer, we see U2B’s [D7] output passed through R8 [D7] and the non-inverting input of U2A [D2]. This input is extended as a bus to which EQ sections bass 1 [D6] and Bass 2 [D5] are connected. These will introduce dips into the audio response. Section Bass 3 [D4] is connected to a potentiometer straddling U2A non-inverting and inverting inputs. When the wiper is moved toward the noninverting input, the section introduces a dip; when moved toward the inverting input, a peak.
Each of the EQ sections utilizes a gyrator-connected op amp in conjunction with a series capacitor to simulate an LCR series tuned circuit. The values of the capacitors and resistors are chosen to implement EQ curves. Each EQ section has optional steering resistors that could allow other curves to be implemented in the future with the same card. There are also some spare sections not currently used.
S1 [B2] selects either the FLUSH or the SURFACE mount EQ curve, while potentiometer R33 [D1] provides a boost/cut range of adjustment of the 90 Hz bass region.
