Rear Panel

iI. CROSSOVER—(Bi-amplifier control) Sets the frequency at which your signal is split into high and low components. This always affects the Low and High Out {GG and JJ} jacks. This only affects the *LF and *HF speaker Outputs {OO and RR} when *Bi- Amp mode {HH} is selected.

JJ.HIGH OUT—TRS1line level, 1/4" output. Supplies high frequen- cies; useful for connection to an external power amplifier in a bi-amp configuration. NOTE: This output is always active, inde- pendent of the positions of the mode switches {HH and PP}.

KK..Tuner Out—Plug your instrument tuner in here. This TRS1 output can also be used as an always-active, tube-influenced direct output.

LL..IN—An alternate input to input 1 on the front panel; useful for wireless receivers. This input is disabled when a plug is inserted into input 1 on the front panel.

MM..MAIN BREAKERS—Protects the power amplifiers from electri- cal faults and circuit overloads. If a breaker has tripped (button pops out), switch the Power {Z} OFF and allow the unit to cool down. Inspect your speakers, all connections and other equip- ment for damage before pressing each circuit breaker back in to reset them.

NN..POWER CORD SOCKET—Connect the included** power cord to a properly wired AC electrical outlet in accordance with the voltage and frequency ratings specified on the rear panel of your amplifier.

** The SM-1500 uses a heavy duty power cord to supply the high power requirements. To ensure safe operation: If an extension cord is required, use only one extra-heavy gauge cord (10 AWG or heavier) that is no longer than absolutely necessary.

OO..PARALLEL RIGHT (LOW FREQUENCY) SPEAKER OUTPUTS— Connect right channel (or low frequency) speakers to these three jacks in any combination. The total impedance load of these speakers should ideally be 2 ohms and must never be less than 2 ohms. The power handling capacity of these speakers must be at least 750 watts.

The SM-1500 furnishes both 1/4" and Speakon® speaker con- nections. Use the Speakon® jacks whenever possible to take advantage of their superior electrical efficiency and secure connectors. All three jacks on each side are full range and wired in parallel. Read the Speaker Guidelines section below before connecting speakers.

PP.NORMAL / BRIDGE SWITCH—Selects a core mode of opera- tion for the SM-1500 power amplifiers. Each mode uses different speaker outputs and master volumes. Turn OFF the SM-1500 while switching modes and connections. Use the tip of a pen to reach the recessed button:

 •  Normal Mode—The power amplifiers operate separately as right and left channels (in Stereo mode {HH}) or as low and high channels (in Bi-Amp mode). In Normal Mode: use the Parallel Right (*LF) and Left (*HF) speaker Outputs {OO and RR} and both Volume knob {Y} sections.

 •  Bridge Mode—The power amplifiers are bridged together to operate as one monolithic power block. In Bridge mode: use the one center speaker output {QQ} and the inner Volume {Y} knob alone.

QQ..MONO (BRIDGE) MODE SPEAKER OUTPUT—One Speakon® speaker output jack is available in Bridge Mode. The total impedance load of this speaker(s) should ideally be 4 ohms and must never be less than 4 ohms. The power handling capacity of this speaker(s) must be at least 1500 watts. Read the Speaker Guidelines section below before connecting speakers.

RR..PARALLEL LEFT (HIGH FREQUENCY) SPEAKER OUTPUTS— Connect left channel (or high frequency) speakers to these three jacks in any combination. The total impedance load of these speakers should ideally be 2 ohms and must never be less than 2 ohms. The power handling capacity of these speakers must be at least 750 watts.

1TRS Balanced Jacks

NOTE: Jacks {FF, GG, JJ and KK} are balanced TRS (Tip/Ring/Sleeve) types and are designed

to accept either TRS or TS (Tip/Sleeve) plugs:

Tip=positive (+) Ring=negative (–) and Sleeve=ground.

While standard shielded TS "mono" guitar cables may certainly be used, the use of "stereo" TRS cables may improve signal-to-noise ratio and/or reduce hum, especially when longer connections are required.
