7 Key to Callouts 1. Fault LED - Indicates a blown fuse. 2. High Power LED - Indicates amplifier power on in "High Power" mode. 3. High Current LED - Indicates amplifier power on in "High Current" mode. 4. Main Fuse - Main power supply fuse.
8 4 Ohm Sub Channel Watts 12 volts 14.4 volts 0 50 100 150 200 250 REFERENCE POWER SUPP LY DESIGN The Reference705s employs an extremely efficient unregulated pulse - width modulated power supply.
9 INS TA LL ATION STEP 1 SETTING THE HIGH POWER/HIGH CURRENT SWITCH (applies to subwoofer channel only) The Reference705s’ subwoofer channel can be switched between “High Power” and “High Current” modes.
10 SELECTING THE CROSSOVER MODES The Reference705s incorporates a sophisticated, fully adjustable electronic crossover for each of its two pairs of channels and subwoofer channel. The Reference705s can drive a full system without need of an outboard electronic crossover.
11 SELECTING INPUT MODES The Reference705s can be driven with either one, two, or three pairs of stereo inputs. If your source unit has front and rear outputs, you can take advantage of its fading capability by driving the Reference705s in 5 channel mode with two pairs of inputs .
12 INS TA LL ATION STEP 5 WIRING POWER AND GROUND To assure maximum output from the Reference705s, use high quality, low - loss power and ground cables. The Reference705s will accept up to 4 gauge power and gr ound cables, which is the only size recommended.
13 WIRING DIAGRAM WIRING (continued) CIRCUIT BREAKERS/FUSES EXTERNAL Like all car audio amplifiers, the Reference705s must be protected with a fuse or circuit breaker located within 18” of the batt ery. This will prevent a fire in the event of a shorted cable.
14 INS TALLATION AND MOUNTING 1. AMPLIFIER LOCATION The Reference705s employs highly efficient circuitry and Soundstream's unique Chassisink TM design to maintain lower operating temperatures.
15 INS TA LL ATION STEP 7 LEVEL SETTING The input levels are adjusted by means of the input level controls located on the front of the amplifier. This is a unique dual - stage circuit that adjusts both level and gain. This topology maintains better Signal to Noise ratio s even with low output sources.
16 CROSSOVER ADJUSTMENTS In most car audio ins tallations, there is a tendency for a “midbass boom.” Because of their interior dimensions, most cars will resonate or ring at these midbass frequencies. If we design the system so there is less musical information in this region, the final response is v ery smooth and natural sounding.
17 INS TA LL ATION STEP 9 LSE.Q THEORY AND USE LSE.Q is a proprietary subwoofer control circuit included with the Reference705s amplifier. It is capable of both removing subsonic energy in program material and providing a variable boost at low frequencie s.
18 SAMPLE SYSTEM #1 2 - way front to rear fade with constant bass 4 channels of input 4 channels of 2 - way high pass, sub channel in low pass.
19 SAMPLE SYSTEM #2 3 - way with midrange bandpass 2 channels of input 2 channels of tweeter high pass, 2 channels of midrange.
20 SAMPLE SYSTEM #3 3 - way with midbass bandpass and subwoofer to midbass/satellite fading 4 channels of input 2 channels of midbass bandp ass, 2 channels of high pass, sub channel in low pass (High .
21 SAMPLE SYSTEM #4 2 - way in 3 channel mode with fading bass 4 channels of input 2 channels of bridged high pass, sub channel in low pass.
22 PROTECTION CIRCUITRY Your Reference705s is protected against both overheating and short circuits by means of the following circuits: • Main power supply fuses (Maxi - fuse at 40 amps) • Smart Power Supply Thermal Rollback activating at 85°C. • A fail - safe thermal protection circuit activating at 95°C.
23 SPECIFIC ATIONS POWER OUTPUT CROSSOVER SPECIFICATIONS (all continuously variable): 2 - way High Pass: 12 dB/octave, 60 - 240 Hz Low Pass: 24 dB/octave, 30 - 120 Hz 3 - way Tweeter High Pass/Midrang.
